Class EventMessageDrivenInitiator

java.lang.Object
  org.ikasan.framework.initiator.AbstractInitiator
      org.ikasan.framework.initiator.messagedriven.JmsMessageDrivenInitiatorImpl
          org.ikasan.framework.initiator.messagedriven.EventMessageDrivenInitiator

All Implemented Interfaces:

javax.jms.MessageListener, Initiator, JmsMessageDrivenInitiator, ListenerSetupFailureListener, MonitorSubject

public class EventMessageDrivenInitiator
extends JmsMessageDrivenInitiatorImpl

A JmsMessageDrivenInitiator implementation that seeks to recreate and fire an Events based on JMS messages. This implementation expects that the incoming message data represents a previously serialised (for JMS publication) Event. TODO the Event serialisation and deserialisation code needs to be tightly bound
