public interface Callable
extends UMOEventListener

Callable is used to provide UMOs with an interface that supports event calls. UMO components do not have to implement this interface, though the onCall method provides an example lifecycle method that is executed when an event is received for the implementing component.

Method Detail

onCall

public Object onCall(UMOEventContext eventContext)
              throws Exception
Passes the event to the listener

Parameters:
eventContext - the context of the current event being process
Returns:
Object this object can be anything. When the UMOLifecycleAdapter for the component receives this object it will first see if the Object is an UMOMessage if not and the Object is not null a new message will be created using the returned object as the payload. This new event will then get published via the configured outbound router if-
  1. One has been configured for the UMO.
  2. the setStopFurtherProcessing(true) wasn't called on the event context event.
Throws:
Exception - if the event fails to process properly. If exceptions aren't handled by the implementation they will be handled by the exceptionListener associated with the component
