+# <a name="intro"></a>Introduction to Coherence
+
+[Coherence](http://coherence.java.net/) is scalable, fault-tolerant, cloud-ready,
+distributed platform for building grid-based applications and reliably storing data.
+The product is used at scale, for both compute and raw storage, in a vast array of
+industries including critical financial trading systems, high performance telecommunication
+products and eCommerce applications to name but a few. Typically these deployments
+do not tolerate any downtime and Coherence is chosen due its novel features in
+death detection, application data evolvability, and the robust, battle-hardened
+core of the product allowing it to be seamlessly deployed and adapt within any ecosystem.
+
+At a high level, Coherence provides an implementation of the all too familiar Java `Map`
+interface but rather than storing the associated data in the local process it is partitioned
+(or sharded if you prefer) across a number of designated remote nodes. This allows
+applications to not only distribute (and therefore scale) their storage across multiple
+processes, machines, racks, and data centers but also to perform grid-based processing
+to truly harness the cpu resources of the machines. The Coherence interface `NamedCache`
+(an extension of `Map`) provides methods to query, aggregate (map/reduce style) and
+compute (send functions to storage nodes for locally executed mutations) the data set.
+These capabilities, in addition to numerous other features, allows Coherence to be used
+as a framework to write robust, distributed applications.
+
+# <a name="acquire"></a>How to Get Coherence Community Edition
+
+For more details on how to obtain and use Coherence, please see the Coherence CE [README](https://github.com/oracle/coherence/README.md).
+
+# <a name="intro_cpp"></a>Introduction to Coherence for C++
+
+Coherence for C++ allows C++ applications to access Coherence clustered services, including data,
+data events, and data processing from outside the Coherence cluster. Typical uses of Coherence
+for C++ include desktop and web applications that require access to Coherence caches.
+
+Coherence for C++ consists of a native C++ library that connects to a Coherence\*Extend clustered
+service instance running within the Coherence cluster using a high performance TCP/IP-based
+communication layer. This library sends all client requests to the Coherence\*Extend clustered
+service which, in turn, responds to client requests by delegating to an actual Coherence
+clustered service (for example, a partitioned or replicated cache service).
+
+A NamedCache instance is retrieved by using the `CacheFactory::getCache(...)` API call.
+After it is obtained, a client accesses the `NamedCache` in the same way as it would if it
+were part of the Coherence cluster. The fact that `NamedCache` operations are being sent to a
+remote cluster node (over TCP/IP) is completely transparent to the client application.
+
+> **_NOTE:_** The C++ client follows the interface and concepts of the Java client, and
+> users familiar with Coherence for Java should find migrating to Coherence for C++ straightforward.
+
+See [Developing Remote Clients for Oracle Coherence](https://docs.oracle.com/en/middleware/fusion-middleware/coherence/12.2.1.4/develop-remote-clients/creating-c-extend-clients.html)
+for further details.
+
+# <a name="build"></a>Building
+
+## Prerequisites
+
+1. A supported hardware platform and C++ compiler. See [Supported Environments for Coherence C++ Client](https://docs.oracle.com/en/middleware/fusion-middleware/coherence/12.2.1.4/install/installing-client-distribution.html#GUID-49C698DD-D34A-416D-A71C-566C32824CEA).
+1. Oracle Java 8 JDK
+1. Apache Ant version 1.7.0 or later
+1. [Ant-Contrib](http://ant-contrib.sourceforge.net/) version 1.0b3
+1. Ant-Contrib [cpptasks](http://ant-contrib.sourceforge.net/cpptasks/index.html) version 1.0b4
+
+## Building the shared library
+
+The Coherence for C++ build system is based on Ant. To build Coherence for C++:
+
+1. Clone this repository
+1. Download Apache Ant version 1.7.0 or later and install it at `tools/internal/common/ant`
+1. Download ant-contrib-1.0b3.jar and install it at `tools/internal/common/ant-contrib/lib`
+1. Download cpptasks-1.0b4.jar and install it at `tools/internal/common/ant-contrib/lib`
+1. Set the `JAVA_HOME` environment variable to point to the Oracle JDK 8 home
+1. `cd bin`
+1. On unix flavor platforms source `cfglocal.sh` from a bash shell (e.g. `. cfglocal.sh`).  On windows open a Visual Studio native tools command prompt and run `cfgwindows.cmd`
+1. `cd ../prj/coherence`
+1. `ant -Dbuild.type=release clean build dist` - can take from 20 minutes to over an hour depending on platform type and CPU speed
+
+The resulting files:
+
+* `dist/14.1.2.0.0b0/include` - the public header files
+* `dist/14.1.2.0.0b0/lib` - the Coherence for C++ shared library
+
+# <a name="cli-hello"></a>CLI Hello Coherence Example
+
+The following example illustrates starting a **storage enabled** Coherence Server,
+followed by a Coherence for C++ console application. Using the console, data is
+inserted and retrieved. The console is then terminated and restarted and data is once again
+retrieved to illustrate the permanence of the data.
+
+## Prerequisites
+
+1. The Coherence for C++ shared library see [Building](#build)
+1. [Coherence Community Edition](https://github.com/oracle/coherence) coherence.jar
+  
+## Build Sanka
+
+Sanka is a command line tool which can be used to run the `main` method on Coherence C++ classes
+
+1. Set the `JAVA_HOME` environment variable to point to the Oracle JDK 8 home
+1. `cd bin`
+1. On unix flavor platforms source `cfglocal.sh` from a bash shell (e.g. `. cfglocal.sh`).  On windows open a Visual Studio native tools command prompt and run `cfgwindows.cmd`
+1. `cd ../prj/sanka`
+1. `ant -Dbuild.type=release` build dist
+
+## Start a Coherence server
+
+Unix shell:
+
+```shell script
+$JAVA_HOME/bin/java -Dcoherence.pof.enabled=true -Dcoherence.log.level=6 -jar coherence.jar
+```
+
+Windows command prompt:
+
+```shell script
+"%JAVA_HOME%/bin/java" -coherence.pof.enabled=true -Dcoherence.log.level=6 -jar coherence.jar
+```

+
+Map (welcomes): list
+french = Bonjour
+english = Hello
+spanish = Hola
+```
+
+# <a name="prog-hello"></a>Programmatic Hello Coherence Example
+
+The following example illustrates starting a **storage enabled** Coherence server,
+followed by running the `HelloCoherence` application. The `HelloCoherence` application
+inserts and retrieves data from the Coherence server.
+
+## Prerequisites
+
+1. The Coherence for C++ shared library see [Building](#build)
+1. [Coherence Community Edition](https://github.com/oracle/coherence) coherence.jar
+
+## Build `HelloCoherence`
+

+
+```c++
+#include "coherence/lang.ns"
+
+#include "coherence/net/CacheFactory.hpp"
+#include "coherence/net/NamedCache.hpp"
+#include "coherence/util/Iterator.hpp"
+
+#include <iostream>
+
+using namespace coherence::lang;
+
+using coherence::net::CacheFactory;
+using coherence::net::NamedCache;
+using coherence::util::Iterator;
+
+int main()
+    {
+    try
+        {
+        // access/create the "welcomes" cache in the Coherence cluster
+        NamedCache::Handle hCache = CacheFactory::getCache("welcomes");
+        std::cout << "Accessing cache \"" << hCache->getCacheName()
+                  << "\" containing " << hCache->size() << " entries"
+                  << std::endl;
+
+        hCache->put(String::create("english"), String::create("Hello"));
+        hCache->put(String::create("spanish"), String::create("Hola"));
+        hCache->put(String::create("french"), String::create("Bonjour"));
+
+        // list
+        for (Iterator::Handle hIterator = hCache->entrySet()->iterator();
+             hIterator->hasNext(); )
+            {
+            std::cout << hIterator->next() << std::endl;
+            }
+
+        // disconnect from the Coherence cluster
+        CacheFactory::shutdown();
+        }
+    catch (const std::exception& e)
+        {
+        std::cerr << "error: " << e.what() << std::endl;
+        return 1;
+        }
+    return 0;
+    }
+```
+
+Compile `HelloCoherence.cpp` using the Coherence for C++ header files and shared library:
+
+Using GCC on Linux and macOS:
+
+```shell script
+g++ -Idist/14.1.2.0.0b0/include -lcoherence -L dist/14.1.2.0.0b0/lib -o HelloCoherence HelloCoherence.cpp
+```
+
+From a Visual Studio native tools command prompt on Windows:
+
+```shell script
+cl -Idist\14.1.2.0.0b0\include dist\14.1.2.0.0b0\lib\coherence.lib -o HelloCoherence HelloCoherence.cpp
+```
+
+## Start a Coherence server
+
+Unix shell:
+
+```shell script
+$JAVA_HOME/bin/java -Dcoherence.pof.enabled=true -Dcoherence.log.level=6 -jar coherence.jar
+```
+
+Windows command prompt:
+
+```shell script
+"%JAVA_HOME%/bin/java" -coherence.pof.enabled=true -Dcoherence.log.level=6 -jar coherence.jar
+```
+
+## Run `HelloCoherence`
+
+Unix shell:
+
+```shell script
+export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:dist/14.1.2.0.0b0/lib
+./HelloCoherence
+```
+
+Windows command prompt:
+
+```shell script
+set PATH=%DEV_ROOT%\dist\14.1.2.0.0b0\lib;%PATH%
+HelloCoherence
+```
+
+# <a name="testing"></a>Testing
+
+Coherence for C++ has unit and functional tests to validate builds and code changes.
+
+## Prerequisites
+
+1. The Coherence for C++ shared library see [Building](#build)
+1. [Perl](https://www.perl.org/)
+1. Download [CxxTest](https://cxxtest.com/) version 3.10.1 and install it at `tools/internal/common/cxxtest`

+as of the date such litigation is filed.
+
+4. Redistribution. You may reproduce and distribute copies of the

+
+6. Trademarks. This License does not grant permission to use the trade

+
+8. Limitation of Liability. In no event and under no legal theory,
+whether in tort (including negligence), contract, or otherwise,
+unless required by applicable law (such as deliberate and grossly
+negligent acts) or agreed to in writing, shall any Contributor be
+liable to You for damages, including any direct, indirect, special,
+incidental, or consequential damages of any character arising as a
+result of this License or out of the use or inability to use the

+GNU LESSER GENERAL PUBLIC LICENSE
+
+Version 3, 29 June 2007
+
+Copyright (c) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+
+Everyone is permitted to copy and distribute verbatim copies of
+this license document, but changing it is not allowed.
+
+This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+0. Additional Definitions.  As used herein, “this License� refers
+to version 3 of the GNU Lesser General Public License, and the “GNU
+GPL� refers to version 3 of the GNU General Public License.
+
+“The Library� refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+An “Application� is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a
+mode of using an interface provided by the Library.
+
+A “Combined Work� is a work produced by combining or linking an
+Application with the Library. The particular version of the Library
+with which the Combined Work was made is also called the “Linked
+Version�.
+
+The “Minimal Corresponding Source� for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source
+code for portions of the Combined Work that, considered in isolation,
+are based on the Application, and not on the Linked Version.
+
+The “Corresponding Application Code� for a Combined Work means the
+object code and/or source code for the Application, including any
+data and utility programs needed for reproducing the Combined Work
+from the Application, but excluding the System Libraries of the
+Combined Work.
+
+1. Exception to Section 3 of the GNU GPL.
+You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+2. Conveying Modified Versions.
+If you modify a copy of the Library, and, in your modifications, a 
+facility refers to a function or data to be supplied by an Application 
+that uses the facility (other than as an argument passed when the facility 
+is invoked), then you may convey a copy of the modified version:
+
+a) under this License, provided that you make a good faith effort
+to ensure that, in the event an Application does not supply the
+function or data, the facility still operates, and performs whatever
+part of its purpose remains meaningful, or 
+b) under the GNU GPL, with none of the additional permissions of this 
+License applicable to that copy.
+
+3. Object Code Incorporating Material from Library Header Files.
+The object code form of an Application may incorporate
+material from a header file that is part of the Library. You may
+convey such object code under terms of your choice, provided that,
+if the incorporated material is not limited to numerical parameters,
+data structure layouts and accessors, or small macros, inline
+functions and templates (ten or fewer lines in length), you do both
+of the following:
+
+a) Give prominent notice with each copy of the object code that the
+Library is used in it and that the Library and its use are covered
+by this License.
+b) Accompany the object code with a copy of the GNU GPL and this 
+license document.
+
+4. Combined Works.
+You may convey a Combined Work under terms of your choice that, taken
+together, effectively do not restrict modification of the portions
+of the Library contained in the Combined Work and reverse engineering
+for debugging such modifications, if you also do each of the
+following:
+
+a) Give prominent notice with each copy of the Combined Work that
+the Library is used in it and that the Library and its use are
+covered by this License.
+b) Accompany the Combined Work with a copy of the GNU GPL and this
+license document.
+c) For a Combined Work that displays copyright notices during execution, 
+include the copyright notice for the Library among these notices, as well as a
+reference directing the user to the copies of the GNU GPL and this
+license document.
+d) Do one of the following: 
+0) Convey the Minimal Corresponding Source under the terms of this License, and the
+Corresponding Application Code in a form suitable for, and under
+terms that permit, the user to recombine or relink the Application
+with a modified version of the Linked Version to produce a modified
+Combined Work, in the manner specified by section 6 of the GNU GPL
+for conveying Corresponding Source.
+1) Use a suitable shared library mechanism for linking with the Library.
+A suitable mechanism is onethat (a) uses at run time a copy of the Library 
+already present on the user's computer system, and (b) will operate properly with a
+modified version of the Library that is interface-compatible with
+the Linked Version.
+e) Provide Installation Information, but only if you would otherwise be required
+to provide such information under section 6 of the GNU GPL, and only to the
+extent that such information is necessary to install and execute a modified
+version of the Combined Work produced by recombining or relinking the Application
+with a modified version of the Linked Version. (If you use option
+4d0, the Installation Information must accompany the Minimal
+Corresponding Source and Corresponding Application Code. If you use
+option 4d1, you must provide the Installation Information in the
+manner specified by section 6 of the GNU GPL for conveying Corresponding
+Source.)
+5. Combined Libraries.
+You may place library facilities that are a work based on the Library side
+by side in a single library together with other library facilities that
+are not Applications and are not covered by this License, and convey 
+such a combined library under terms of your choice, if you do both of
+the following:
+
+a) Accompany the combined library with a copy of the same work based
+on the Library, uncombined with any other library facilities,
+conveyed under the terms of this License.
+b) Give prominent notice with the combined library that part of it is
+a work based on the Library, and explaining where to find the accompanying
+uncombined form of the same work.
+6. Revised Versions of the GNU Lesser General Public License.
+The Free Software Foundation may publish revised
+and/or new versions of the GNU Lesser General Public License from
+time to time. Such new versions will be similar in spirit to the
+present version, but may differ in detail to address new problems
+or concerns.
+
+Each version is given a distinguishing version number. If the Library
+as you received it specifies that a certain numbered version of the
+GNU Lesser General Public License “or any later version� applies
+to it, you have the option of following the terms and conditions
+either of that published version or of any later version published
+by the Free Software Foundation. If the Library as you received it
+does not specify a version number of the GNU Lesser General Public
+License, you may choose any version of the GNU Lesser General Public
+License ever published by the Free Software Foundation.
+
+If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License
+shall apply, that proxy's public statement of acceptance of any
+version is permanent authorization for you to choose that version
+for the Library.

+* <ul>
+*      <li>Portable</li>
+*      <li>PortableProperty</li>

+*
+* This class has one strategy of metadata discovery: accessor.

+        *
+        * If the argument is <code>0xfff0000000000000L</code>, the result
+        * is negative infinity.
+        *
+        * If the argument is any value in the range
+        * <code>0x7ff0000000000001L</code> through
+        * <code>0x7fffffffffffffffL</code> or in the range
+        * <code>0xfff0000000000001L</code> through
+        * <code>0xffffffffffffffffL</code>, the result is a NaN. No IEEE
+        * 754 floating-point operation provided can distinguish between two
+        * NaN values of the same type with different bit patterns. Distinct
+        * values of NaN are only distinguishable by use of the
+        * <code>Float64::float64ToBits</code> method.
+        *
+        * In all other cases, let <i>s</i>, <i>e</i>, and <i>m</i> be three
+        * values that can be computed from the argument:
+        * <blockquote><pre>
+        * uint64_t s = ((bits &gt;&gt; 63) == 0) ? 1 : -1;
+        * uint64_t e = (int)((bits &gt;&gt; 52) & 0x7ffL);
+        * uint64_t m = (e == 0) ?
+        *                 (bits & 0xfffffffffffffL) &lt;&lt; 1 :
+        *                 (bits & 0xfffffffffffffL) | 0x10000000000000L;
+        * </pre></blockquote>
+        * Then the floating-point result equals the value of the mathematical
+        * expression <i>s</i>&middot;<i>m</i>&middot;2<sup><i>e</i>-1075</sup>.
+        *
+        * Note that this method may not be able to return a
+        * <code>float64_t</code> NaN with exactly same bit pattern as the
+        * <code>uint64_t</code> argument. IEEE 754 distinguishes between two
+        * kinds of NaNs, quiet NaNs and <i>signaling NaNs</i>.  The
+        * differences between the two kinds of NaN are generally not
+        * visible. Arithmetic operations on signaling NaNs turn them into
+        * quiet NaNs with a different, but often similar, bit pattern.
+        * However, on some processors merely copying a signaling NaN also
+        * performs that conversion. In particularm copying a signaling NaN to
+        * return it to the calling method may perform this conversion. So
+        * <code>bitsToFloat64</code> may not be able to return a
+        * <code>float64_t</code> with a signaling NaN bit pattern.
+        * Consequently, for some <code>uint64_t</code> values,
+        * <code>float64ToBits(bitsToFloat64(start))</code> may <i>not</i>
+        * equal <code>start</code>. Moreover, which particular bit patterns
+        * represent signaling NaNs is platform dependent; although all NaN
+        * bit patterns, quiet or signaling, must be in the NaN range
+        * identified above.
+        *
+        * @param l  any <code>uint64_t</code> integer

+* and start a

+* between the client and the server (including Protocol negotiation); if the
+* handshake is successful, the Connection will be transitioned to the open
+* state.
+* <p/>
+* A Connection itself is not used to send and receive Message objects.
+* Rather, one or more {@link Channel} objects may be created from the
+* Connection and used to exchange Message objects of a known {@link Protocol}
+* with a peer. A Channel may be  {@link #openChannel opened} to a named
+* {@link Channel.Receiver} registered by the peer. Alternatively, an
+* "anonymous" Channel (a back-Channel) may be {@link #createChannel created}
+* by one peer and returned to the other, where it must be
+* {@link #acceptChannel accepted} before it can be used.
+* <p/>
+* Once finished with the Connection, an application should release all
+* resources held by the Connection by calling the {@link #close} method.
+* Closing a Connection also closes all Channel objects created by the
+* Connection and renders the Connection unusable. Attempting to use a closed

+/**
+* The ConnectionManager is the base SPI (Service Provider Interface) for both
+* {@link ConnectionAcceptor} and {@link ConnectionInitiator} implementations.
+* <p/>
+* Implementations of this interface use a provider-specific mechanism to
+* establish a bi-directional communication channel between two endpoints,
+* represented by a {@link Connection}. Some implementations restrict data
+* transfer between endpoints within a single JVM, whereas others enable two
+* processes to exchange data. Advanced implementations allow communication
+* between processes on different machines, for example using TCP sockets or
+* JMS.
+* <p/>
+* Before a Connection can be established between a ConnectionInitiator
+* (client) and ConnectionAcceptor (server), one or more Protocol instances
+* must be registered with the ConnectionManager on each. During Connection
+* establishment, the ConnectionInitiator sends information about each
+* registered Protocol. A compatable set of Protocol instances (or superset)
+* must be registered with the acceptor's ConnectionManager in order for the
+* Connection to be established.
+* <p/>
+* Establishing a Connection is assumed to be a heavyweight operation that may
+* allocate significant resources within and outside the JVM. For example, a
+* TCP-based implementation of this interface may implement a Connection using
+* a persistent Socket connection with a remote server. However, once
+* established, successive uses of the same Connection should be relatively
+* lightweight. In other words, a Connection object, once opened, should
+* appear to be persistent from the perspective of the user until closed.
+* Additionally, underlying transports used by implementations must be both
+* reliable and ordered.
+* <p/>
+* Once a Connection is established, either client or server may open a
+* {@link Channel} to a {@link Channel.Receiver} registered by its peer and
+* use it to send and receive {@link Message} objects to/from the peer.

+* The Logger class is used to log messages for a specific system
+* or application component.
+*
+* Each logger instance has an associated logging level. Only Log
+* messages that meet or exceed this level are logged. Currently,
+* the Logger defines 10 logging levels (from highest to lowest
+* level):
+* level_internal (All messages without a Log level)
+* level_error    (Error messages)
+* level_warning  (Warning messages)
+* level_d4
+* level_d5
+* level_d6
+* level_d7
+* level_d8
+* level_d9
+*
+* Additionally the logger defines two "psuedo" levels that
+* instruct the Logger to either log all messages or to not log
+* any messages:
+*
+* level_all
+* level_none
+*
+* Log messages are logged using the log() method. There are
+* several versions of the log() method that allow both string
+* messages and Exceptions to be logged. The logger uses a string
+* template to format the Log message before it is logged using
+* the underlying logging mechanism. The template may contain the
+* following parameterizable strings:
+*
+* {date}    The date and time that the message was logged
+* {uptime}  The duration the process has been running for
+* {level}   The level of the log message
+* {thread}  The thread that logged the message
+* {text}    The text of the message
+* {product} The executing assembly of the product
+* {version} The executing assembly version
+*
+* Subclasses of the Logger are free to define additional
+* parameters.
+*
+* The Logger class uses a LogOutput to log messages to an
+* underlying logging mechanism, such as Out, Error, or a file.
+* See the configure() method for additional detail

+* The Evolvable interface is implemented by classes that require forwards-
+* and backwards-compatibility of their serialized form. An Evolvable class
+* has an integer version identifier <tt>n</tt>, where <tt>n >= 0</tt>. When
+* the contents and/or semantics of the serialized form of the Evolvable class
+* changes, the version identifier is increased. Two versions identifiers,
+* <tt>n1</tt> and <tt>n2</tt>, indicate the same version iff
+* <tt>n1 == n2</tt>; the version indicated by <tt>n2</tt> is newer than the
+* version indicated by <tt>n1</tt> iff <tt>n2 &gt; n1</tt>.
+*
+* The Evolvable interface is designed to support the evolution of classes by
+* the addition of data. Removal of data cannot be safely accomplished as long
+* as a previous version of the class exists that relies on that data.
+* Modifications to the structure or semantics of data from previous versions
+* likewise cannot be safely accomplished as long as a previous version of the
+* class exists that relies on the previous structure or semantics of the
+* data.
+*
+* When an Evolvable is deserialized, it retains any unknown data that has
+* been added to newer versions of the class, and the version identifier for
+* that data format. When the Evolvable is subsequently serialized, it
+* includes both that version identifier and the unknown future data.
+*
+* When an Evolvable is deserialized from a data stream whose version
+* identifier indicates an older version, it must default and/or calculate the
+* values for any data fields and properties that have been added since that
+* older version. When the Evolvable is subsequently serialized, it includes
+* its own version identifier and all of its data. Note that there will be no
+* unknown future data in this case; future data can only exist when the
+* version of the data stream is newer than the version of the Evolvable
+* class.

+* A PofAnnotationSerializer provides annotation based (de)serialization.
+* This serializer must be instantiated with the intended class which is
+* eventually scanned for the presence of the following annotations.
+* <ul>
+*      <li>coherence::io::pof::annotation::Portable</li>
+*      <li>coherence::io::pof::annotation::PortableProperty</li>
+* </ul>
+*
+* This serializer supports classes iff they are annotated with the type level
+* annotation; Portable. This annotation is a marker indicating the ability
+* to (de)serialize using this serializer.
+*
+* All methods annotated with PortableProperty are explicitly
+* deemed POF serializable with the option of specifying overrides to
+* provide explicit behaviour such as:
+* <ul>
+*      <li>explicit POF indexes</li>
+*      <li>Custom coherence::io::pof::reflect::Codec to
+*          specify concrete implementations / customizations</li>
+* </ul>
+*
+* The PortableProperty::getIndex() (POF index) can be omitted iff the
+* auto-indexing feature is enabled. This is enabled by instantiating this
+* class with the \c fAutoIndex constructor argument. This feature
+* determines the index based on any explicit indexes specified and the name
+* of the portable properties. Currently objects with multiple versions is
+* not supported. The following illustrates the auto index algorithm:
+* <table border=1>
+*   <tr><td>Name</td><td>Explicit Index</td><td>Determined Index</td></tr>
+*   <tr><td>c</td><td>1</td><td>1</td>
+*   <tr><td>a</td><td></td><td>0</td>
+*   <tr><td>b</td><td></td><td>2</td>
+* </table>
+*

+* Evolvable.

+/**
+* The PofWriter interface provides the capability of writing a set of
+* non-primitive types ("user types") to a POF stream as an ordered sequence
+* of indexed properties.
+*
+* The serialized format of a POF user type is as follows:
+* <ul>
+*   <li>Type Identifier</li>
+*   <li>Version Identifier</li>
+*   <li>[Property Index, Property Value]*</li>
+*   <li>-1</li>
+* </ul>
+* The type identifier is an integer value greater than or equal to zero that
+* identifies the non-primitive type. The type identifier has no explicit
+* or self-describing meaning within the POF stream itself; in other words,
+* the type identifier does not contain the actual class definition. Instead,
+* the PofWriter and corresponding {@link PofReader} share a
+* {@link PofContext} which contains the necessary meta-data, including type
+* identifier to type mappings.
+*
+* The version identifier is used to support both backwards and forwards
+* compatibility of serialized POF user types. Versioning of user types allows
+* the addition of new properties to a user type, but not the replacement or
+* removal of properties that existed in a previous version of the user type.
+*
+* When a version <i>v1</i> of a user type written by a PofWriter is read by
+* a PofReader that supports version <i>v2</i> of the same user type, the
+* PofReader returns default values for the additional properties of the User
+* Type that exist in <i>v2</i> but do not exist in <i>v1</i>. Conversely,
+* when a version <i>v2</i> of a user type written by a PofWriter is read by
+* a PofReader that supports version <i>v1</i> of the same user type, the
+* instance of user type <i>v1</i> must store those additional opaque
+* properties for later encoding. The PofReader enables the user type to
+* store off the opaque properties in binary form (see {@link
+* PofReader#readRemainder PofReader::readRemainder}). When the user type
+* is re-encoded, it must be done so using the version identifier
+* <i>v2</i>, since it is including the unaltered <i>v2</i> properties. The
+* opaque properties are subsequently included in the POF stream using the
+* {@link #writeRemainder} method.
+*
+* Following the version identifier is an ordered sequence of index/value
+* pairs, each of which is composed of a property index encoded as
+* non-negative integer value whose value is greater than the previous
+* property index, and a property value encoded as a POF value. The user type
+* is finally terminated with an illegal property index of -1.
+*
+* Note: To read a property that was written using a PofWrite method, the
+* corresponding read method on {@link PofReader} must be used. For example,
+* if a property was written using {@link #writeByteArray},
+* {@link PofReader#readByteArray PofReader::readByteArray} must be used to
+* read the property.

+* A TypedHandle implementation which supports auto-boxing.
+*
+* To support boxing a managed class defines an inner-type named "BoxedType",
+* and includes a public static "create" method which takes that type. The
+* BoxedType defines the type which the BoxHandle can use to create a managed
+* object from. Alternatively the BoxHandle declaration can identify the
+* "BoxedType" via a secondary template parameter.
+*
+* Managed classes which wish to be auto-boxing may use this handle type
+* when defining their Handle and View definitions. See String as an
+* example.
+*
+* When used with integral types a natural ambiguity is introduced when
+* setting or comparing a BoxHandle to NULL, as it also an integral type. In
+* such cases one may use the is_null(h) and clear_handle(h) helper functions
+* to ensure the correct behavior.
+*
+* BoxHandle can be configured as strict, or non-strict. In strict mode
+* (the default), derefencing a NULL BoxHandle will result in a
+* NullPointerException. In non-strict mode, dereferencing a BoxHandle will
+* result in the BoxedType's default value being returned.

+* exceptions to be stored as data member or local variables outside of a
+* try/catch block and to be safely re-thrown at a later time.
+*
+* New exception classes are declared using the throwable_spec<> helper template.

+/**
+* FinalHandle is an immutable thread-safe handle used by an Object to
+* reference its non-const child Objects.
+*
+* FinalHandles may either be initialized with a value at
+* construction-time, or thereafter via the initialize() function.  A
+* FinalHandle may be initialized only if the following conditions
+* hold:
+* <ul>
+*   <li> The FinalHandle has not already been initialized
+*   (either during construction, or via <tt>initialize()</tt>)
+* </ul>
+* For example:
+*
+* @code
+* class Foo
+*   : public class_spec<Foo>
+*   {
+*   friend class factory<Foo>;
+*
+*   protected:
+*     Foo()
+*       : f_hBar(self()) // construction without initialization
+*       {}
+*
+*   public:
+*     void setBar(Bar::Handle hBar)
+*       {
+*       initialize(f_hBar, hBar); // post-construction initialization
+*       }
+*
+*   private:
+*     FinalHandle<Bar> f_hBar;
+*   };
+* @endcode
+*
+* FinalHandles transfer the constness of their parent Object. When a
+* FinalHandle is accessed from within a const method of the enclosing
+* "parent" class, it will only provide const access to the Object which it
+* references. If the enclosing Object becomes only accessed via views the
+* FinalHandle will also automatically, and permanently switch its reference
+* type from a handle to a view.
+*
+* Note: In the rare case that a FinalHandle is declared via the mutable
+*       keyword, the FinalHandle must be informed of this fact by setting
+*       fMutable to true during construction.  A mutable FinalHandle will
+*       will return Handles from const methods of the class it is a data
+*       member of.  The FinalHandle cannot be reassigned to reference another
+*       object.

+*  <li>[custom]  The name of a class registered with the SystemClassLoader.</li>
+* </ul>
+*
+* In the case where a custom class is specified, it must implement this
+* interface.  The custom analyzer will be initialized as soon as the class
+* is registered with the SystemClassLoader. As static initialization order

+* objects created earlier in the static initialization order.
+*
+* The active analyzer may be obtained from the System::getHeapAnalyzer()
+* method.
+*
+* The HeapAnalyzer and Snapshot interfaces are intentionally narrow.

+/**
+* Managed is an adaptor class which transforms a pre-existing class into a
+* Coherence managed Object.
+*
+* The resulting object will be usable both as the supplied data type and as a
+* Coherence managed object. As a managed object it is suitable for storage in
+* Coherence caches.
+*
+* The managed object must be created using its associated static create
+* methods, which support either default construction, or copy construction
+* from the custom type. The managed object's life-cycle is dictated by reference
+* counting, and it may not be manually deleted.
+*
+* To be compatible with the Managed template the following set of functions
+* must be defined for the supplied type:
+* <ul>
+*   <li>zero parameter constructor (public or protected):
+*       <code>CustomType::CustomType()</code></li>
+*   <li>copy constructor (public or protected):
+*       <code>CustomType::CustomType(const CustomType&)</code></li>
+*   <li>equality comparison operator:
+*       <code>bool operator==(const CustomType&, const CustomType&)</code>
+*   <li>basic_stream output function:
+*       <code>template<typename Char, typename Traits> std::basic_ostream<Char, Traits>& operator<<(std::basic_ostream<Char, Traits>& out, const CustomType&)</code></li>
+*   <li>hash function:
+*       <code>size_t hash_value(const CustomType&)</code></li>
+* </ul>
+*
+* A example of a conforming class would be:
+* @code
+* class Address
+*   {
+*   public:
+*     Address(const std::string& sCity, const std::String& sState, int nZip)
+*       : m_sCity(sCity), m_sState(sState), m_nZip(nZip) {}
+*
+*     Address(const Address& that)
+*       : m_sCity(that.m_sCity), m_sState(that.m_sState), m_nZip(that.m_nZip) {}
+*
+*   protected:
+*     Address()
+*       : m_nZip(0) {}
+*
+*   public:
+*     std::string  getCity()  const {return m_sCity;}
+*     std::string  getState() const {return m_sState;}
+*     int          getZip()   const {return m_nZip;}
+*
+*   private:
+*     const std::string m_sCity;
+*     const std::string m_sState;
+*     const int         m_nZip;
+*   };
+*
+* bool operator==(const Address& addra, const Address& addrb)
+*   {
+*   return addra.getZip()   == addrb.getZip() &&
+*          addra.getState() == addrb.getState() &&
+*          addra.getCity()  == addrb.getCity();
+*   }
+*
+* template<typename Char, typename Traits, class T> std::basic_ostream<Char, Traits>& operator<<(std::basic_ostream<Char, Traits>& out, const Address& addr)
+*   {
+*   out << addr.getCity() << ", " << addr.getState() << "  " << addr.getZip();
+*   return out;
+*   }
+*
+* size_t hash_value(const Address& addr)
+*   {
+*   return (size_t) addr.getZip();
+*   }
+* @endcode
+*
+* Serialization support may be added by specializing the following free-functions:
+* <ul>
+*   <li>serializer:
+*       <code>void serialize<CustomType>(coherence::io::pof::PofWriter::Handle, const CustomType&)</code></li>
+*   <li>deserializer:
+*       <code>CustomType deserialize<CustomType>(coherence::io::pof::PofReader::Handle)</code></li>
+* </ul>
+*
+* The serialization functions do not need to be defined within the source file
+* of the original data type. They only need to be linked into the application,
+* and registered with the SystemPofContext via the COH_REGISTER_MANAGED_CLASS
+* macro.
+*
+* @code
+* #include "coherence/io/pof/SystemPofContext.hpp"
+*
+* #include "Address.hpp"
+*
+* using namespace coherence::io::pof;
+*
+* COH_REGISTER_MANAGED_CLASS(1234, Address);
+*
+* template<> void serialize<Address>(PofWriter::Handle hOut, const Address& addr)
+*   {
+*   hOut->writeString(0, addr.getCity());
+*   hOut->writeString(1, addr.getState());
+*   hOut->writeInt32 (2, addr.getZip());
+*   }
+*
+* template<> Address deserialize<Address>(PofReader::Handle hIn)
+*   {
+*   std::string sCity  = hIn->readString(0);
+*   std::string sState = hIn->readString(1);
+*   int         nZip   = hIn->readInt32 (2);
+*
+*   return Address(sCity, sState, nZip);
+*   }
+* @endcode
+*
+* An example usage of the resulting managed type would be:
+* @code
+* // construct the non-managed version as usual
+* Address office("Redwood Shores", "CA", 94065);
+*
+* // the managed version can be initialized from the non-managed version
+* // the result is a new object, which does not reference the original
+* Managed<Address>::View vOffice = Managed<Address>::create(office);
+* String::View           vKey    = "Oracle";
+*
+* // the managed version is suitable for use with caches
+* hCache->put(vKey, vAddr);
+* vOffice = cast<Managed<Address>::View>(hCache->get(vKey));
+*
+* // the non-managed class's public methods/fields remain accessible
+* assert(vOffice->getCity()  == office.getCity());
+* assert(vOffice->getState() == office.getState());
+* assert(vOffice->getZip()   == office.getZip());
+*
+* // conversion back to the non-managed type may be performed using the
+* // non-managed class's copy constructor.
+* Address officeOut = *vOffice;
+* @endcode

+/**
+* MemberHolder is a thread-safe handle implementation which supports
+* referencing Objects as either Handles or Views. MemberHolder can safely be
+* used in place of View but adds the ability to attempt a safe down cast to a
+* Handle. This differs from the C++ const_cast in that the down cast will only
+* succeed if the MemberHolder had been assigned from a Handle, an assignment
+* from a View results in a MemberHolder whose down cast operation will throw
+* a ClassCastException.
+*
+* MemberHolder is not for general use, instead it is a convenience handle type
+* which can be used for container like classes, which need to be able to
+* contain both Handles and Views.
+*
+* Note: In the rare case that a MemberHolder is declared via the mutable
+*       keyword, the MemberHolder must be informed of this fact by setting
+*       fMutable to true during construction.

+/**
+* Object is the base class for all Coherence managed objects.
+*
+* The interface for Object provides support basic operations such as equality,
+* hashing, printing, cloning, synchronization, and notification.
+*
+* Objects have automatically managed memory, through built-in thread-safe
+* reference counting. The reference count is maintained through the use of
+* smart-pointers, known as handles. All references to an Object should be
+* maintained through a handle rather then a raw pointer, or C++ reference.
+*
+* Each managed class includes inner definitions of handles which can be used
+* to reference instance of that class, as well as derived class instances.
+* These definitions provide functionality corresponding to const and non-const
+* pointers. The names for these handles are Handle for the non-const, View for
+* the const pointer equivalent, and Holder for a hybrid. The Holder type acts
+* like a View but allows for a safe down-cast to a Handle, which will only
+* succeed if the Holder was assigned from a Handle, and will fail with a
+* ClassCastException if it had been assigned from a View. Note that in
+* documentation the term "handle" is used to describe any handle type
+* including Handle/View/Holder, while "Handle" refers to the specific
+* "Handle" type.
+*
+* The handles are aware of the inheritance hierarchy, allowing direct
+* assignment from a handle from a derived class to a handle of a base class.
+* These up-casts are automatic, and an explicit cast operation is rarely
+* needed, except to resolve compiler type ambiguities. Assignment from a View
+* to a Handle is also automatic as the const-interface of a class can
+* naturally be considered a base-class. Assignment of a handle to a derived
+* type is not automatic, and requires an explicit down-cast via the coherence
+* cast<H>(h) function. The template parameter is the desired handle type, while
+* the function parameter is the handle to cast. If the supplied handle is
+* non-NULL and is not an instance of the class associated with H, a
+* ClassCastException will be thrown. There is a corresponding instanceof<H>(h)
+* method which can be used to perform the type-check without the risk of
+* triggering an exception. The use of instanceof, is optional, and is only
+* needed if the type is actually in question.
+*
+* @code
+* Object::Handle hObject = ...
+* Foo::Handle    hFoo;
+*
+* if (instanceof<Foo::Handle>(hObject))
+*   {
+*   hFoo = cast<Foo::Handle>(hObject);
+*   }
+* @endcode
+*
+* These convenience handles are not thread-safe, and should not be used in a
+* multi-threaded context. They should only be used as local variables, though
+* they are free to reference objects shared by many threads. The most common
+* place where thread-safe handles are needed is for data members of managed
+* objects. For these cases the Coherence API includes a variety of thread-safe
+* handles/views. It is necessary that any class which extends from Object use
+* thread-safe handles when referencing other managed Objects.
+*
+* By convention managed objects will also block direct external access to
+* their constructor and destructor. Constructors are accessed via public
+* static "create" factory methods. The copy constructor is accessed via the
+* public virtual "clone" method. Destructors are protected and destruction
+* is triggered automatically when the internal reference count reaches zero.

+        * </pre>
+        * With this approach many threads may concurrently access various
+        * array elements without having to synchronize on the array itself,
+        * and contend with each other. The use of common monitors also avoids
+        * the overhead of allocating a unique monitor per index. This example
+        * additionally makes use of the array's identity hash code to avoid
+        * frequent collisions against other atomic arrays for the same indices.
+        *
+        * As they are shared, these monitors will apply to any number of
+        * unrelated entities, and as such certain precautions must be employed
+        * when using them.
+        * <ul>
+        * <li>The holder of a common monitor MUST not synchronize on any other
+        *     common monitor. Failure to adhere to this precaution will result
+        *     in a deadlock.
+        * <li>Notifications on a common monitor MUST use notifyAll() rather
+        *     then notify(), as there may be unrelated threads waiting for
+        *     notification on the same monitor which could consume a single
+        *     notification. Thus the only way to ensure that the desired
+        *     thread does receive notification is to notify all threads
+        *     waiting on the monitor.
+        * <li>Threads waiting for a notification must protect themselves
+        *     against spurious style wakeups. While this is a general, though
+        *     often overlooked part of the normal use of notification, with
+        *     common monitors it is far more likely that a thread will be
+        *     notified due to an unrelated event.
+        * <li>A thread which is holding synchronization on a common monitor
+        *     should avoid blocking operations as this could block unrelated
+        *     threads which happen to be utilizing the same common monitor.
+        * </ul>
+        * The ideal number of common monitors in a process is one per
+        * concurrently executing thread. As this number is generally unknown
+        * the default number of monitors set to a relatively high value. The
+        * value may also be manually specified via the
+        * <code>tangosol.coherence.commonmonitors</code> system property.

+ * TimeoutBlock provides a mechanism for allowing a thread to interrupt itself if it doesn't return
+ * to a specific call site within a given timeout.  TimeoutBlock instances are intended to be
+ * used only with the COH_TIMEOUT_AFTER helper macro.  Once constructed a TimeoutBlock attempts to ensure that
+ * the corresponding block completes within the specified timeout and if it does not the thread will
+ * self-interrupt.  Exiting the timeout block will automatically clear any interrupt present on the thread
+ * and in such a case an InterruptedException will be thrown.
+ *
+ * <pre>
+ * try

+ * catch (InterruptedException::View vEx)
+ *     {
+ *     // thread timed out or was otherwise interrupted
+ *     }
+ * </pre>
+ *
+ * Note that when catching the InterruptedException the preferred form is to surround the COH_TIMEOUT block with a try/catch
+ * rather then embed the try/catch within the block.  This allows handling of cases where the thread gets interrupted but
+ * the doSomething() method does not choose to throw the InterruptedException, in which case the TimeoutBlock destructor will
+ * throw it, but this happens as the block terminates and thus would not be catchable within the block.
+ *

+* By convention each Object implementation will include two typedefs for

+/**
+* A handle implementation which supports referencing Objects as either
+* Handles or Views. TypedHolder can safely be used in place of View
+* but adds the ability to attempt a safe down cast to a Handle. This differs
+* from a const_cast in that the down cast will only succeed if the
+* TypedHolder had been assigned from a Handle, an assignment from a View
+* results in a TypedHolder whose down cast operation will fail with a
+* ClassCastException.
+*
+* TypedHolder is not for general use, instead it is a convenience handle type
+* which can be used for container like classes, which need to be able to
+* contain both Handles and Views.
+*
+* As with TypedHandles, TypedHolders are not thread-safe, and should not be
+* used in a multi-threaded context even if protected by external
+* synchronization. They should only be used as local variables. The most
+* common place where thread-safe holders are needed is for object data
+* members. For these cases the Coherence API includes a thread-safe variant
+* MemberHolder.

+/**
+ * TypedMethod provides a template based implementation for building Methods
+ * which delegate to member function pointers.
+ *
+ * Rather then making direct use of this class it is recommended to utilize
+ * the following helper macros.  For each of these methods there are nine
+ * variants suffixed 0..8 which indicate the number of arguments the method
+ * takes.
+ *
+ * - COH_CONSTRUCTOR     defines a Method representing a constructor
+ * - COH_METHOD          defines a Method representing an instance method
+ * - COH_STATIC_METHOD   defines a Method representing a static method
+ * - COH_MANAGED_METHOD  defines a Method representing an instance on a
+ *                       Managed<> class
+ *
+ * - COH_OVERLOADED_CONSTRUCTOR    defines an overloaded constructor
+ * - COH_OVERLOADED_METHOD         defines an overloaded instance method
+ * - COH_OVERLOADED_STATIC_METHOD  defines an overloaded static method
+ *
+ * Additionally the following macros will create setter and getter Methods
+ * for a "property".
+ *
+ * - COH_PROPERTY          defines setter/getter for a object property
+ * - COH_BOX_PROPERTY      defines a setter/getter for a value type property
+ * - COH_MANAGED_PROPERTY  defines a setter/getter for a value type on a
+ *                         Managed<> class
+ *
+ * These macros output Method objects which can then be registered with
+ * their corresponding Class object.  This registration can either be
+ * performed as part of the Class registration, or it can be done in multiple
+ * COH_REGISTER_METHOD blocks, allowing the Method definition to reside
+ * next to the actual method implementation.

+* WeakHandles are a TypedHandle like wrapper around WeakReferences.
+* WeakReferences allow one Object to safely reference another without blocking
+* it from being destroyed. WeakReferences are necessary when building Object
+* graphs to avoid leaking the Object graph due to cyclic references.
+*
+* WeakReferences are automatically NULL'd out when their referenced Object
+* is destroyed. Additionally if the weakly referenced Object becomes only
+* referenced via Views, then the WeakReference and corresponding WeakHandle
+* will only return View to the Object, if an attempt is made to obtain a
+* Handle a NULL will be returned instead.
+*
+* WeakHandles behave like MemberHandles by transferring their constness to
+* their referenced Object. As with MemberHandle WeakHandles are a thread-safe
+* handle implementation.  As such they require references to both the
+* referenced "child" Object, as well as the owning "parent" Object. As with
+* MemberView the parent object must inherit from Object.
+*
+* If the weakly referenced Object will always be referenced as a View then
+* using the WeakView class would be more appropriate

+* Note: In the rare case that a WeakHandle is declared via the mutable

+/**
+* WeakHolders are a TypedHolder like wrapper around WeakReferences.
+* WeakReferences allow one Object to safely reference another without blocking
+* it from being destroyed. WeakRefereces are necessary when building Object
+* graphs to avoid leaking the Object graph due to cyclical references.
+*
+* WeakReferences are automatically NULL'd out when their referenced Object
+* is destroyed. Additionally if the weakly referenced Object becomes only
+* referenced via Views, then the WeakReference and corresponding WeakHandle
+* will only return View to the Object, if an attempt is made to obtain a
+* Handle a NULL will be returned instead.
+*
+* WeakHolders are wrappers for MemberHolder, and provide a thread-safe handle
+* implementation.  As such they require references to both the referenced
+* "child" Object, as well as the owning "parent" Object. As with MemberHolder
+* the parent object must inherit from Object.
+*
+* Note: In the rare case that a WeakHolder is declared via the mutable
+*       keyword, the WeakHolder must be informed of this fact by setting
+*       fMutable to true during construction.

+/**
+* WeakReferences allow one Object to safely reference another without blocking
+* it from being destroyed. WeakReferences are necessary when building Object
+* graphs to avoid leaking the Object graph due to cyclical references.
+*
+* WeakReferences provide getter methods to safely obtain a normal Handle to the
+* weakly referenced Object if it still exists. Once the Object becomes only
+* weakly referenced its associated WeakReference will be automatically NULL'd
+* out so that the Object may be reclaimed.
+*
+* Consider a simple case of an Object tree, where parent's reference their
+* children, and children reference their parents. With normal reference
+* counting handles, the tree would be leaked even once all external references
+* to the tree have been dropped. To resolve this issue the tree could be
+* constructed such that parents reference their children via normal Handles,
+* but children reference their parents via WeakReferences. This way as long as
+* the parent is externally referenced its entire sub-tree will be retained.
+* Once all external Handles to the parent are dropped the entire tree will be
+* reclaimed as only WeakReferences would hold it together.
+*
+* Similar to MemberHandles, WeakReferences transfer their constness to their
+* referenced Object. That is if a View to a WeakReference is held then only the
+* View to the referenced Object will be available.
+*
+* Do to the need to call the get() which returns an Object::View or Handle
+* and then perform a cast, WeakReferences are somewhat cumbersome to make use
+* of. WeakHandle and WeakView are TypedHandle like wrappers for WeakReference
+* which makes using WeakReferences much simpler. In most cases these should be
+* used rather than direct use of WeakReferences.

+* DefaultConfigurableCacheFactory provides a facility to access caches
+* declared in a "cache-config.dtd" compliant configuration file.
+*
+* This class is designed to be easily extendable with a collection of factory
+* methods allowing subclasses to customize it by overriding any subset of
+* %cache instantiation routines or even allowing addition of custom schemes.
+*
+* There are various ways of using this factory:
+* <pre>
+*   ConfigurableCacheFactory::Handle factory =
+*       DefaultConfigurableCacheFactory::create(sPath);
+*   ...
+*   NamedCache::Handle cacheOne = factory->ensureCache("one");
+*   NamedCache::Handle cacheTwo = factory->ensureCache("two");
+* </pre>
+* This approach allows an easy customization by extending the
+* DefaultConfigurableCacheFactory and changing the instantiation line:
+* <pre>
+*   ConfigurableCacheFactory::Handle factory =
+*       CustomConfigurableCacheFactory::create();
+*   ...
+* </pre>
+*
+* Another option is using the static version of the "ensureCache" call:
+* <pre>
+*   NamedCache cacheOne = CacheFactory::getCache("one");
+*   NamedCache cacheTwo = CacheFactory::getCache("two");
+* </pre>
+* which uses an instance of ConfigurableCacheFactory obtained by
+* {@link CacheFactory#getConfigurableCacheFactory()}.

+/**
+* The PriorityTask interface allows to control the ordering in which a
+* service schedules tasks for execution using a thread pool and limit their
+* execution times to a specified duration. Instances of PriorityTask
+* typically also implement either PriorityTask or Runnable interface.
+*
+* Depending on the value returned by the #getSchedulingPriority()
+* method, the scheduling order will be one of the following:
+* <ul>
+* <li> #schedule_standard - a task will be scheduled for execution in
+*      a natural (based on the request arrival time) order;
+* <li> #schedule_first - a task will be scheduled in front of any
+*      equal or lower scheduling priority tasks and executed as soon as any
+*      of worker threads become available;
+* <li> #schedule_immediate - a task will be immediately executed by
+*      any idle worker thread; if all of them are active, a new thread will
+*      be created to execute this task.
+* </ul>
+*
+* A best effort will be made to limit the task execution time according to
+* the value returned by the #getExecutionTimeoutMillis() method. However,
+* it should be noted that:
+* <ul>
+* <li> for tasks with the scheduling priority of schedule_immediate, factors
+*      that could make the execution time longer than the timeout value are
+*      long GC pauses and high network latency;
+* <li> if the service has a task backlog (when there are more tasks scheduled
+*      for execution than the number of available worker threads), the
+*      request execution time (measured from the client's perspective) for
+*      tasks with the scheduling priorities of schedule_standard or
+*      schedule_first could be longer and include the time those tasks were
+*      kept in a queue before invocation;
+* <li> the corresponding service is free to cancel the task execution before
+*      the task is started and call the #runCanceled method if it's
+*      known that the client is no longer interested in the results of the
+*      task execution.
+* </ul>
+*
+* In addition to allowing control of the task execution (as scheduled and
+* measured on the server side), the PriorityTask interface could also be used
+* to control the request time from the calling thread perspective (measured
+* on the client). A best effort will be made to limit the request time (the
+* time period that the calling thread is blocked waiting for a response from
+* the corresponding service) to the value returned by the
+* #getRequestTimeoutMillis() method.
+*
+* It should be noted that the request timeout value (RT) could be grater
+* than, equal to or less than the task execution timeout value (ET). The
+* value of RT which is less than ET indicates that even though the task
+* execution is allowed to take longer period of time, the client thread will
+* not wait for a result of the execution and will be able to handle a timeout
+* exception if it arises. Since the time spent by the task waiting in the
+* service backlog queue does not count toward the task execution time, a
+* value of RT that is equal or slightly greater than ET still leaves a
+* possibility that the client thread will throw a TimeoutException before the
+* task completes its execution normally on a server.

+ * Assume that we receive a continuous and concurrent stream of individual
+ * operations on multiple threads in parallel. Let's also assume those individual
+ * operations have relatively high latency (network or database-related) and
+ * there are functionally analogous [bulk] operations that take a collection of
+ * arguments instead of a single one without causing the latency to grow
+ * linearly, as a function of the collection size. Examples of operations and
+ * topologies that satisfy these assumptions are:
+ * <ul>
+ *   <li> get() and getAll() methods for the NamedCache API for the
+ *        partitioned cache service topology;
+ *   <li> put() and putAll() methods for the NamedCache API for the
+ *        partitioned cache service topology;
+ * </ul>
+ *
+ * Under these assumptions, it's quite clear that the bundler could achieve a
+ * better utilization of system resources and better throughput if slightly
+ * delays the individual execution requests with a purpose of "bundling" them
+ * together and passing int32_to a corresponding bulk operation. Additionally,
+ * the "bundled" request should be triggered if a bundle reaches a "preferred
+ * bundle size" threshold, eliminating a need to wait till a bundle timeout is

+/**
+* Map implementation that wraps two maps - a front map (assumed to be
+* "inexpensive" and probably "incomplete") and a back map (assumed to
+* be "complete" and "correct", but more "expensive") - using a
+* read-through/write-through approach.
+*
+* If the back map implements ObservableMap interface, the CachingMap provides
+* four different strategies of invalidating the front map entries that have
+* changed by other processes in the back map:
+*
+* listen_none strategy instructs the cache not to listen for invalidation
+*     events at all. This is the best choice for raw performance and
+*     scalability when business requirements permit the use of data which
+*     might not be absolutely current.  Freshness of data can be guaranteed
+*     by use of a sufficiently brief eviction policy for the front map;
+* listen_present strategy instructs the CachingMap to listen to the
+*     back map events related <b>only</b> to the items currently present in
+*     the front map. This strategy works best when each instance of a front
+*     map contains distinct subset of data relative to the other front map
+*     instances (e.g. sticky data access patterns);
+* listen_all strategy instructs the CachingMap to listen to <b>all</b>
+*     back map events. This strategy is optimal for read-heavy tiered access
+*     patterns where there is significant overlap between the different
+*     instances of front maps;
+* listen_auto strategy instructs the CachingMap implementation to switch
+*     automatically between listen_present and listen_all strategies based
+*     on the cache statistics.
+* listen_logical strategy instructs the CachingMap to listen to <b>all</b>
+*     back map events that are <b>not synthetic</b>. A synthetic event could
+*     be emitted as a result of eviction or expiration. With this
+*     invalidation strategy, it is possible for the front map to contain
+*     cache entries that have been synthetically removed from the back
+*     (though any subsequent re-insertion will cause the corresponding
+*     entries in the front map to be invalidated).
+*
+* The front map implementation is assumed to be thread safe; additionally
+* any modifications to the front map are allowed only after the corresponding
+* lock is acquired against the ControlMap.
+*
+* <b>Note:</b> NULL values are not cached in the front map and therefore this
+* implementation is not optimized for maps that allow NULL values to be
+* stored.

+/**
+* A generic cache manager.
+*
+* The implementation is thread safe and uses a combination of
+* Most Recently Used (MRU) and Most Frequently Used (MFU) caching
+* strategies.
+*
+* The cache is size-limited, which means that once it reaches its maximum
+* size ("high-water mark") it prunes itself (to its "low-water mark"). The
+* cache high- and low-water-marks are measured in terms of "units", and each
+* cached item by default uses one unit. All of the cache constructors, except
+* for the default constructor, require the maximum number of units to be
+* passed in. To change the number of units that each cache entry uses, either
+* set the Units property of the cache entry, or extend the Cache
+* implementation so that the inner Entry class calculates its own unit size.
+* To determine the current, high-water and low-water sizes of the cache, use
+* the cache object's Units, HighUnits and LowUnits properties. The HighUnits
+* and LowUnits properties can be changed, even after the cache is in use.
+* To specify the LowUnits value as a percentage when constructing the cache,
+* use the extended constructor taking the percentage-prune-level.
+*
+* Each cached entry expires after one hour by default. To alter this
+* behavior, use a constructor that takes the expiry-millis; for example, an
+* expiry-millis value of 10000 will expire entries after 10 seconds. The
+* ExpiryDelay property can also be set once the cache is in use, but it
+* will not affect the expiry of previously cached items.
+*
+* The cache can optionally be flushed on a periodic basis by setting
+* the FlushDelay property or scheduling a specific flush time by setting
+* the FlushTime property.
+*
+* Cache hit statistics can be obtained from the CacheHits, CacheMisses,
+* HitProbability, KeyHitProbability and CompositeHitProbability read-only
+* properties. The statistics can be reset by invoking resetHitStatistics.
+* The statistics are automatically reset when the cache is cleared (the clear
+* method).
+*
+* The OldCache implements the ObservableMap interface, meaning it provides
+* event notifications to any interested listener for each insert, update and
+* delete, including those that occur when the cache is pruned or entries
+* are automatically expired.
+*
+* This implementation is designed to support extension through inheritence.
+* When overriding the inner Entry class, the OldCache.instantiateEntry factory
+* method must be overridden to instantiate the correct Entry sub-class. To
+* override the one-unit-per-entry default behavior, extend the inner Entry
+* class and override the calculateUnits method.
+*
+* The C++ version of OldCache requires a call release(), in order for it to
+* be collected.  Not including a call to release will result in the OldCache
+* being leaked.

+* boxing_map provides an STL-like map adapter around a coherence::util::map,

+* non-managed types. The key and value template parameters specify the managed
+* class which will be stored in the Map. Other then the definition, the access
+* to the keys and values may use either the managed view type or the
+* corresponding unmanaged type. This also allows for easy copying of mapped
+* entries from a std::map to coherence maps and caches.
+*
+* @code
+* boxing_map<Managed<Foo>, Managed<Bar> > mycache
+*         (CacheFactory::getCache("mycache")); // declare boxing adapter
+*
+* Foo foo(...); // initialize non-managed object Foo
+* Bar bar(...); // initialize non-managed object Bar

+* mycache[foo] = bar;         // insert directly into cache via auto-boxing

+* all optional list operations, and permits all elements, including
+* <tt>NULL</tt>. This class is optimized operations on the front and back of
+* the list to facilitate use as a queue or deque.
+*
+* The <tt>size</tt>, <tt>get</tt>, <tt>set</tt>, <tt>listIterator</tt>
+* operations run in constant time.  The <tt>add</tt> operation runs in
+* <i>amortized constant time</i>, that is, adding n elements requires O(n)
+* time.  All of the other operations run in linear time (roughly speaking).
+* The constant factor is low compared to that for the <tt>LinkedList</tt>
+* implementation.
+*
+* Each <tt>CircularArrayList</tt> instance has a <i>capacity</i>.
+* The capacity is the size of the array used to store the elements in the
+* list.  It is always at least as large as the list size.  As elements are
+* added to an CircularArrayList, its capacity grows automatically.  The
+* details of the growth policy are not specified beyond the fact that adding
+* an element has constant amortized time cost.
+*
+* An application can increase the capacity of an <tt>CircularArrayList</tt>
+* instance before adding a large number of elements using the
+* <tt>ensureCapacity</tt> operation.  This may reduce the amount of
+* incremental reallocation.
+*
+* <strong>Note that this implementation is not synchronized.</strong> If
+* multiple threads access a <tt>CircularArrayList</tt> concurrently, and at
+* least one of the threads modifies the list structurally, it <i>must</i> be
+* synchronized externally.  (A structural modification is any operation that
+* adds or deletes one or more elements, or explicitly resizes the backing
+* array; merely setting the value of an element is not a structural
+* modification.)  This is typically accomplished by synchronizing on some
+* object that naturally encapsulates the list.
+*
+* The iterators returned by this class's <tt>listIterator</tt> methods are
+* fail-fast: if list is structurally modified at any time after the iterator
+* is created, in any way except through the iterator's own remove or add
+* methods, the iterator will throw a ConcurrentModificationException.  Thus,
+* in the face of concurrent modification, the iterator fails quickly and
+* cleanly, rather than risking arbitrary, non-deterministic behavior at an
+* undetermined time in the future.
+*
+* Note that the fail-fast behavior of an iterator cannot be guaranteed as
+* it is, generally speaking, impossible to make any hard guarantees in the
+* presence of unsynchronized concurrent modification.  Fail-fast iterators
+* throw <tt>ConcurrentModificationException</tt> on a best-effort basis.
+* Therefore, it would be wrong to write a program that depended on this
+* exception for its correctness: <i>the fail-fast behavior of iterators
+* should be used only to detect bugs.</i>

+* An implementation of coherence::util::Map that is thread-safe, but unlike

+* map implementation, relying on an array of pre-allocated entry structures.
+* This approach significantly reduces the cost of insertion into the map as
+* there is no Entry allocation required except as part of rehashing.  This
+* optimization makes it an good candidate for short lived maps.
+*
+* Though thread-safe Hashtable is optimized for single-threaded access, and
+* assumes that in most cases escape-analysis will elide the synchronization.
+* If the Map will be accessed concurrently by many threads it is likely that
+* SafeHashMap would be a better choice.  If the Map will largely live on a
+* single thread, or be short lived then Hashtable is a good choice.
+*
+* Note: Hashtable's entryset iterator returns Map::Entry objects which are
+* only valid until the iterator is advanced.  If the Entry needs to be
+* retained longer then it should either be cloned or an shallow copy should
+* be created.

+* A SortedMap extended with navigation methods returning the
+* closest matches for given search targets. Methods lowerKey,
+* floorKey, ceilingKey, and higherKey return only the associated
+* keys. All of these methods are designed for locating, not
+* traversing entries.
+*
+* Methods subMap, headMap, tailMap differ from the like-named
+* SortedMap methods in accepting additional arguments describing
+* whether lower and upper bounds are inclusive versus exclusive.
+* Sub-maps of any NavigableMap must implement the NavigableMap
+* interface.
+*
+* This interface additionally defines methods pollFirstEntry
+* pollLastEntry that return and remove the least and greatest mappings,
+* if any exist, else returning NULL.
+*
+* Implementations of entry-returning methods are expected to
+* return Map.Entry pairs representing snapshots of mappings
+* at the time they were produced, and thus generally do <em>not</em>
+* support the optional Entry.setValue method. Note however
+* that it is possible to change mappings in the associated map using
+* method put.
+*
+* Methods
+* #subMap(Object, Object) subMap(K, K),
+* #headMap(Object) headMap(K), and
+* #tailMap(Object) tailMap(K)
+* are specified to return SortedMap to allow existing implementations
+* of SortedMap to be compatibly retrofitted to implement NavigableMap,
+* but extensions and implementations of this interface are encouraged
+* to override these methods to return NavigableMap.

+/**
+* Use this class in cases that large numbers of threads can operate
+* concurrently with an additional requirement that all threads be blocked for
+* certain operations.  The algorithm is based on a gate concept, allowing
+* threads in (enter) and out (exit), but occasionally shutting the gate (close)
+* such that other threads cannot enter and exit.  However, since threads may
+* "be inside", the gate cannot fully close until they leave (exit).  Once all
+* threads are out, the gate is closed, and can be re-opened (open) or
+* permanently closed (destroy).
+*
+* Each call to enter requires a corresponding call to exit, similar to the
+* implementation of the COH_SYNCHRONIZED macro that calls Object::lock at the
+* the beginning of the synchronized portion and protects the synchronized
+* portion with a try..catch construct that ensures the execution of a
+* Object::unlock call.  For example, the following would ensure proper clean-up
+* using a ThreadGate:
+* </p>
+* The enter/exit calls can be nested; the same thread can invoke enter multiple
+* times as long as exit is invoked a corresponding number of times. The
+* close/open calls work in the same manner.  Lastly, the thread that closes the
+* gate may continue to enter/exit the gate even when it is closed since that
+* thread has exclusive control of the gate.
+* <p>
+* To make usage of these calls easier, the following macros have been defined:
+* <ul>
+*     <li> COH_GATE_ENTER enters and automatically exits the gate
+*     <li> COH_GATE_CLOSE closes and automatically opens the gate
+*     <li> COH_GATE_BAR   bars entry and automatically opens the gate
+* </ul>
+* <pre>
+* COH_GATE_ENTER (hGate) // read lock acquired
+*   {
+*   // read operations go here
+*   // ...
+*   // ...
+*   } // read lock released
+* // outside of sync block
+*
+* COH_GATE_CLOSE (hGate) // write lock acquired
+*   {
+*   // write operations go here
+*   // ...
+*   // ...
+*   } // write lock released
+* // outside of sync block
+*
+* COH_GATE_BAR (hGate) // additional readers are blocked
+*   {
+*   // non-synchronized ops
+*   COH_GATE_CLOSE (hGate) // write lock acquired
+*      {
+*      // ...
+*      // ...

+/**
+* A collection of wrapper classes which expose an underlying collection's
+* contents as explicit types rather then just as Objects.  Essentially these
+* are auto-casting collections.
+*
+* Each typed collection is templated based on one or more handle types
+* to a const coherence::lang::Object Object. For instance:
+* <tt>TypedCollection<String::View></tt> or
+* <tt>TypedMap<String::View, Integer32::View></tt>
+*
+* Alternate handle types may also be used for added functionality,
+* for example: <tt>TypedMap<String::View, BoxHandle<const Integer32> ></tt>
+* produces a TypedMap which will auto-box the supplied values to Integer32,
+* making statements such as <tt>hMap->put("abc", 456)</tt> possible.
+*
+* These typed wrappers only provide a convenience over the underlying
+* collection. Thus they cannot guarantee that external usage of the
+* the underlying collection will not violate the restrictions imposed by the
+* wrapper. For instance Objects of a type other then those specified by
+* this template may exist within the collection.  Any retrieval of those
+* elements from the wrapper will result in ClassCastException.
+* External usage is possible anytime the typed wrapper is passed by its
+* inherited collection interface, i.e. passing a TypedMap as a plain Map.
+*
+* Member functions which take no input parameters cannot have their return
+* type changed. Instead there will be an auxiliary function with the same name
+* plus a "Typed" suffix, e.g. TypedMap::keySetTyped().
+*
+* Example usage:
+* @code
+* typedef TypedCollections::TypedMap<String::View, Integer32::Handle> StringIntMap;
+* StringIntMap::Handle hMap = StringIntMap::create(HashMap::create());
+*
+* hMap->put("abc", Integer32::create(123));  // String's auto-boxing is utilized
+* Integer32::Handle hInt = hMap->get("abc"); // no cast of return type required

+/**
+* The GroupAggregator provides an ability to split a subset of entries in an
+* InvocableMap into a collection of non-intersecting subsets and then
+* aggregate them separately and independently. The splitting (grouping) is
+* performed using the results of the underlying ValueExtractor in such a way
+* that two entries will belong to the same group if and only if the result of
+* the corresponding ValueExtractor#extract extract call produces the
+* same value or tuple (list of values). After the entries are split into the
+* groups, the underlying aggregator is applied separately to each group. The
+* result of the aggregation by the GroupAggregator is a Map that has distinct
+* values (or tuples) as keys and results of the individual aggregation as
+* values. Additionally, those results could be further reduced using an
+* optional Filter object.
+*
+* Informally speaking, this aggregator is analogous to the SQL "group by" and
+* "having" clauses. Note that the "having" Filter is applied independently on
+* each server against the partial aggregation results; this generally implies
+* that data affinity is required to ensure that all required data used to
+* generate a given result exists within a single cache partition.
+* In other words, the "group by" predicate should not span multiple
+* partitions if the "having" clause is used.
+*
+* The GroupAggregator is somewhat similar to the DistinctValues
+* aggregator, which returns back a list of distinct values (tuples) without
+* performing any additional aggregation work.
+*
+* <b>Unlike many other concrete EntryAggregator implementations that are
+* constructed directly, instances of GroupAggregator should only be created
+* using one of the factory methods:</b>
+* #create(ValueExtractor, InvocableMap::EntryAggregator)

+/**
+* The ParallelGroupAggregator provides an ability to split a subset of
+* entries in an InvocableMap into a collection of non-intersecting subsets
+* and then aggregate them separately and independently. The splitting
+* (grouping) is performed using the results of the underlying ValueExtractor
+* in such a way that two entries will belong to the same group if and only if
+* the result of the corresponding ValueExtractor#extract extract call
+* produces the same value or tuple (list of values). After the entries are
+* split into the groups, the underlying aggregator is applied separately to
+* each group. The result of the aggregation by the GroupAggregator is a Map
+* that has distinct values (or tuples) as keys and results of the individual
+* aggregation as values. Additionally, those results could be further reduced
+* using an optional Filter object.
+*
+* Informally speaking, this aggregator is analogous to the SQL "group by" and
+* "having" clauses. Note that the "having" Filter is applied independently on
+* each server against the partial aggregation results; this generally implies
+* that data affinity is required to ensure that all required data used to
+* generate a given result exists within a single cache partition.
+* In other words, the "group by" predicate should not span multiple
+* partitions if the "having" clause is used.
+*
+* The ParallelGroupAggregator is somewhat similar to the DistinctValues
+* aggregator, which returns back a list of distinct values (tuples) without
+* performing any additional aggregation work.
+*
+* Unlike many other concrete EntryAggregator implementations that are
+* constructed directly, instances of ParallelGroupAggregator should only be
+* created indirectly by using the factory method of GroupAggregator.

+/**
+* The KeyExtractor is a special purpose ValueExtractor implementation that
+* serves as an indicator that a query should be run against the key objects
+* rather than the values. The major difference between the KeyExtractor and a
+* standard ReflectionExtractor is that when used in various EntryFilter
+* implementations it forces the evaluation of entry keys rather than entry
+* values.
+*
+* For example, consider a key object that consists of two properties:
+* "FirstName" and "LastName". To retrieve all keys that have a value of the
+* "LastName" property equal to "Smith", the following query could be used:
+* <pre>
+* ValueExtractor::View extractor = KeyExtractor::create("getLastName");
+* Set::View setKeys = cache->keySet(EqualsFilter::create(extractor, "Smith"));
+*
+* </pre>
+* As of Coherence 3.5, the same effect can be achieved for subclasses of the
+* AbstractExtractor, for example:
+* <pre>
+* ValueExtractor::View vExtractor = ReflectionExtractor::create("getLastName",
+*       NULL, AbstractExtractor::KEY);
+* Set::View setKeys = cache->keySet(EqualsFilter::create(vExtractor, "Smith"));
+* </pre>

+/**
+* POF-based ValueExtractor implementation.
+* PofExtractor takes advantage of POF's indexed state to extract part of an
+* object without needing to deserialize the entire object.
+* <p/>
+* POF uses a compact form in the serialized value when possible. For example,
+* some numeric values are represented as special POF intrinsic types in which
+* the type implies the value. As a result, POF requires the receiver of a
+* value to have implicit knowledge of the type. PofExtractor uses the type
+* supplied in the constructor as the source of the type information. If the
+* type is void, PofExtractor will infer the type from the serialized state.
+* See {@link PofConstants} for the list of the POF types.
+* <p/>
+* In C++ the type is expressed by type_info which is obtained from the typeid
+* operator.
+*
+* Example where extracted value is float64_t:
+* <pre><code>
+*     ValueExtractor::Handle hExtractor =
+*         PofExtractor::create(typeid(float64_t), 0);
+* </code></pre>
+*
+* Example where extracted value should be inferred from the serialized state:
+* <pre><code>
+*     ValueExtractor::Handle hExtractor =
+*         PofExtractor::create(typeid(void), 0);

+/**
+* Filter which limits the scope of another filter according to the key
+* association information.
+* <p/>
+* This filter is intended to be used to optimize queries for partitioned
+* caches that utilize any of the key association algorithms (by implementing
+* either coherence::net::partition::KeyAssociator or
+* coherence::net::cache::KeyAssociation) to ensure placement of
+* all associated entries in the same distributed cache partition (and
+* therefore in the same storage-enabled cluster node). Using the
+* KeyAssociatedFilter will instruct the distributed cache to apply the
+* wrapped filter only to the entries stored at the cache service node that
+* owns the specified host key.
+*
+* <b>Note 1:</b> This filter must be the outermost filter and cannot be used
+* as a part of any composite filter (AndFilter, OrFilter, etc.)
+*
+* For example, consider two classes called <i>Parent</i> and <i>Child</i>
+* that are stored in separate caches using <i>ParentKey</i> and
+* <i>ChildKey</i> objects respectively. The Parent and Child classes have a
+* <i>getId</i> method that returns a Long value that uniquely identifies the
+* object. Similarly, the ParentKey and ChildKey classes have a <i>getId</i>
+* method that uniquely identifies the corresponding cached object.
+* Futhermore, the Child and ChildKey classes include a <i>getParentId</i>
+* method that returns the Long identifier of the Parent object.
+*
+* There are two ways to ensure that Child objects are collected with their
+* Parent objects (in the same storage-enabled cluster node).
+* <ol>
+* <li>Make the ChildKey class implement
+* coherence::net::cache::KeyAssociation as follows:
+* <pre>
+* virtual Object::View getAssociatedKey() const
+*     {
+*     return getParentId();
+*     }</pre>
+* and the ParentKey class implement
+* coherence::net::cache::KeyAssociation as follows:
+* <pre>
+* public: virtual Object::View getAssociatedKey()
+*     {
+*     return getId();
+*     }</pre>
+* Note: a Java version of these classes must also exist and contain the same
+* logic</li>
+* <li>Implement a custom com.tangosol.coherence.net.partition.KeyAssociator
+* in Java which will be processed on the cache servers.
+* </li>
+* </ol>
+* The first approach requires a trivial change to the ChildKey and ParentKey
+* classes, whereas the second requires a new class and a configuration
+* change, but no changes to existing classes.
+* <p/>
+* Now, to retrieve all the Child objects of a given Parent using an optimized
+* query you would do the following:
+* <pre>
+* ParentKey::Handle parentKey = ParentKey::create(...);
+* Integer64::View   parentId  = parentKey->getId();
+*
+* // this Filter will be applied to all Child objects in order to fetch those
+* // for which getParentId() returns the specified Parent identifier
+* Filter::View filterEq = EqualsFilter::create(ReflectionExtractor::create(
+*       "getParentId"), parentId);
+*
+* // this Filter will direct the query to the cluster node that currently
+* // owns the Parent object with the given identifier
+* Filter::View filterAsc =  KeyAssociatedFilter::create(filterEq, parentId);
+*
+* // run the optimized query to get the ChildKey objects
+* Set::View setChildKeys = cacheChildren->keySet(filterAsc);
+*
+* // get all the Child objects at once
+* Set::Handle setChildren = cacheChildren->getAll(setChildKeys);
+* </pre>
+* To remove the Child objects you would then do the following:
+* <pre>
+* cacheChildren->keySet()->removeAll(setChildKeys);</pre>

+/**
+* @mainpage
+*
+* Coherence for C++ allows C++ applications to access Coherence clustered
+* services, including data, data events, and data processing from outside
+* the Coherence cluster. Typical uses of Coherence for C++ include desktop
+* and that require access to Coherence caches.
+*
+* The Coherence for C++ API consists of:
+* @li Shared libraries for a variety of compilers and operating systems
+* @li C++ API header files
+* @li API documentation
+*
+* The library allows applications to connect to Coherence*Extend proxies
+* running within the Coherence cluster using a high performance TCP/IP-based
+* communication layer. The library sends all client requests to the
+* Coherence*Extend clustered service which, in turn, responds to client
+* requests by delegating to an actual Coherence clustered service (for example
+* a Partitioned or Replicated cache service). As on other Coherence platforms,
+* C++ Coherence {@link coherence::net::NamedCache caches} are obtained from
+* the {@link coherence::net::CacheFactory CacheFactory}.
+*
+* In order for application data objects to be stored in the cluster they must
+* be serializable to the Coherence POF (Portable Object Format). This may be
+* accomplished by either modifying the data object to implement the
+* {@link coherence::io::pof::PortableObject PortableObject} interface, or
+* though the use of the helper template
+* {@link coherence::lang::Managed Managed<T>}. The latter offers an easy
+* integration route for existing C++ data objects as in most cases no changes
+* to the existing data object code are required.
+*
+* The Coherence for C++ API is pure C++ and is built on top of a managed object
+* model which handles the task of memory management. It is thus not necessary
+* or allowable to manually delete objects returned from or injected into the
+* cache. See {@link coherence::lang::Object Object} for an introduction to the
+* object model.

+    // given type must be bounded by something or the C++ implmentation would

+    // additionally since typeid() absolutely does return a reference this

+/**
+* The Coherence for C++ application launcher.
+*
+* It provides roughly the same functionality as "java.exe", namely it allows
+* for execution of a "public static void main" method from a registered
+* class.  Specifically the class must be registered with the SystemClassLoader
+* as an ExecutableClass.  The benefits of using this approach for starting
+* applications over the traditional C++ method are:
+* - system properties can be specified on the command line
+* - multiple "utility" applications can be bundled in one DLL
+* - exceptions thrown from "main" can be nicely logged
+*
+* This application performs the following tasks:
+* - store command line system properties as process local environment variables
+* - load dynamic libraries
+* - invoke a well known function in the Coherence library.
+*
+* As part of loading the DLLs they are statically initialized which triggers
+* class registration.  The loading of an application library which has been
+* linked with the Coherence library, is what actually triggers the loading
+* of Coherence.  This way the launcher application is able to set environment
+* variables prior to the Coherence library being loaded.
+*
+* This application is not linked against the Coherence library allowing it
+* to work with whatever version the application library had been linked
+* against.  This allows for a single version to support both debug and release
+* versions of the Coherence library.

+* Tests the configuration that can be defined:

+* - factory instance methods with and without parameters
+* - factory static methods with and without parameters
+*
+* Each test method gets a specific cache and puts a
+* name/value in the cache.  The test listener modifies
+* the event, depending on how it was configured.
+*
+* If the cache is configured with a parameter, the parameter
+* is the cache-name, which is passed to the test listener,
+* and is returned as the event value.  
+*
+* If the cache is configured without a parameter, the
+* test listener is instantiated with a test string, which 
+* is returned as the event value.
