Constructor Detail

AbstractMessageReceiver

public AbstractMessageReceiver(Connector connector,
                       FlowConstruct flowConstruct,
                       InboundEndpoint endpoint)
                        throws CreateException

Creates the Message Receiver

Parameters:

connector - the endpoint that created this listener

flowConstruct - the flow construct to associate with the receiver.

endpoint - the provider contains the endpointUri on which the receiver will listen on. The endpointUri can be anything and is specific to the receiver implementation i.e. an email address, a directory, a jms destination or port address.

Throws:

CreateException

FlowConstruct, InboundEndpoint

Method Detail

createLifecycleManager

protected ConnectableLifecycleManager createLifecycleManager()

Specified by:

createLifecycleManager in class AbstractTransportMessageHandler

initialise

public final void initialise()
                      throws InitialisationException

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 AbstractTransportMessageHandler

Throws:

InitialisationException - if a fatal error occurs causing the Mule instance to shutdown

RecoverableException - if an error occurs that can be recovered from
