All Implemented Interfaces:

AnnotatedObject, MuleContextAware, Initialisable, MessageProcessor

public class LoggerMessageProcessor
extends Object
implements MessageProcessor, Initialisable, MuleContextAware, AnnotatedObject

MessageProcessor implementation that logs the current element of a value evaluated from it using an expression evaluator. By default the current messages is logged using the Level.DEBUG level to the 'org.mule.api.processor.LoggerMessageProcessor' category. The level and category can both be configured to suit your needs.

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

Throws:

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

RecoverableException - if an error occurs that can be recovered from

initLogger

protected void initLogger()

process

public MuleEvent process(MuleEvent event)
                  throws MuleException

Description copied from interface: MessageProcessor

Invokes the MessageProcessor.

Specified by:

process in interface MessageProcessor

Parameters:

event - MuleEvent to be processed

Returns:

optional response MuleEvent
