Method Detail

initialise

public void initialise()
                throws InitialisationException
Description copied from interface: Initialisable
Method used to perform any initialisation work. If a fatal error occurs during initialisation an InitialisationException should be thrown, causing the Mule instance to shutdown. If the error is recoverable, say by retrying to connect, a RecoverableException should be thrown. There is no guarantee that by throwing a Recoverable exception that the Mule instance will not shut down.

Specified by:
initialise in interface Initialisable
Overrides:
initialise in class Scriptable
Throws:
InitialisationException

onCall

public Object onCall(UMOEventContext eventContext)
              throws Exception
Description copied from interface: Callable
Passes the event to the listener

Specified by:
onCall in interface Callable
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

populateBindings

protected void populateBindings(javax.script.Bindings namespace,
                                UMOEventContext context)

getBindings

public javax.script.Bindings getBindings()
