Package org.diirt.support.ca Description

Support for Epics 3 data source (channel syntax).

The JCADataSource uses the MultiplexedChannelHandler. The connection payload used is the JCA Channel class directly. The payload for each monitor event is the JCAMessagePayload, which includes both metadata (taken with a GET at connection time) and value (taken from the MONITOR event).

The conversion between JCAMessagePayload and the actual type, is done through the JCATypeAdapter. A JCATypeSupport can be passed directly to the JCADataSource so that one can configure support for different types.
