31 * The Class EnEventListenerImpl is used by the Apex engine implementation to listen for events
32 * coming from the core APEX engine. This listener converts the {@link EnEvent} instances into
33 * {@link ApexEvent} instances using an {@link ApexEvent2EnEventConverter} instance and forwards the
34 * events to an {@link ApexEventListener} instance for outputting to listening applications. The
35 * {@link ApexEventListener} is implemented in the external application communicating with Apex.
