Introduction

This documentation covers the following APIs provided with Apama:

Connectivity Plug-ins

API for writing C++ plug-ins for the connectivity layer. Documentation can be found in the following files:

com::softwareag::connectivity - All connectivity-related classes and free functions
sag_connectivity_plugins.hpp - Implementing plug-ins
sag_plugin_logging.hpp - Support for logging from customer plugins
sag_connectivity_cpp.hpp - Support for the connectivity data model
sag_connectivity_threading.h - cross-platform threading primitives. NOTE: if your compiler supports C++11 std::thread et al then you should use those. This is only provided for older compilers which don't have complete C++11 support.

EPL Plug-ins

API for writing C++ plug-ins for EPL. Documentation can be found in the following files, in addition to those used in the connectivity layer for the type system used for passing data to and from plugins. This API was introduced in 10.0 replacing and deprecating the previous EPL plugin API in C and C++.

com::apama::epl - All EPL plugin-related classes and free functions
epl_plugin.hpp - API for writing EPL plugins

Client API

API for writing applications in C/C++ which connect to Apama components. Documentation can be found in the following filse:

com::apama - All client-related classes and free functions
com::apama::event - Classes for handling events passed over the client API
com::apama::engine - Classes for interacting with the correlator component
engine_client_cpp.hpp - C++ API for Apama clients
engine_client_c.h - C API for Apama clients. NOTE: This is DEPRECATED. The C++ API should be used in preference
