# Oracle Coherence for C++ API Documentation

### 3.6.0.0

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:

- Shared libraries for a variety of compilers and operating systems
- C++ API header files
- 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 caches are obtained from the 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 PortableObject interface, or though the use of the helper template 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 Object for an introduction to the object model.
