Event Processing
This section describes the event processing APIs and how to configure them on top of the Space. The relevant APIs include the Notify Container, which wraps the Space data event session API with event container abstraction, and the Polling Container, which allows you to perform polling receive operations against the Space.
Events that are received by the polling and notify containers are handled by the Event Listener, which is a Space Data Event Listener and the Event Exception Listener.
Regarding FIFO Ordering, XAP supports both non-ordered Entries and FIFO ordered Entries when performing Space operations. XAP also includes JMS message support that is built on top of the core Space architecture.
