Java codec functions to implement
HTML Javadoc documentation for AbstractEventCodec and related classes is provided as part of the Apama documentation set. See the API Reference for Java (Javadoc) for detailed information on the functions that a codec plug-in author needs to implement.
AbstractEventCodec is the constructor. A typical constructor would create a logger using the plug-in name provided (see Logging from IAF plug-ins in Java), make a call to the updateProperties method to deal with the initial property set passed in, and perform any other initialization operations required for the particular event codec being developed.
Note that unlike event transports, codec plug-ins do not have start and stop methods.
See Communication with other layers for information on how the codec layer communicates with the transport layer and Semantic Mapper in upstream and downstream directions.
