Method Detail

intercept

public MuleMessage intercept(Invocation invocation)
                      throws MuleException

getInterceptors

public List getInterceptors()

setInterceptors

public void setInterceptors(List interceptors)

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

Throws:

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

RecoverableException - if an error occurs that can be recovered from

dispose

public void dispose()

Description copied from interface: Disposable

A lifecycle method where implementor should free up any resources. If an exception is thrown it should just be logged and processing should continue. This method should not throw Runtime exceptions.
