public class MessageFilter
extends AbstractFilteringMessageProcessor
implements FlowConstructAware, Lifecycle

Implementation of InterceptingMessageProcessor that filters message flow using a Filter. Is the filter accepts the message then message flow continues to the next message processor. If the filter does not accept the message processor and a message processor is configured for handling unaccepted message then this will be invoked, otherwise null will be returned.

MessageFilter

public MessageFilter(Filter filter,
             boolean throwExceptionOnUnaccepted,
             MessageProcessor messageProcessor)

Parameters:

filter -

throwExceptionOnUnaccepted - throw a FilterUnacceptedException when a message is rejected by the filter?

messageProcessor - used to handler unaccepted messages

Method Detail

accept

protected boolean accept(MuleEvent event)

Specified by:

accept in class AbstractFilteringMessageProcessor

filterUnacceptedException

protected MuleException filterUnacceptedException(MuleEvent event)

Overrides:

filterUnacceptedException in class AbstractFilteringMessageProcessor

getFilter

public Filter getFilter()

setFilter

public void setFilter(Filter filter)

toString

public String toString()

Overrides:

toString in class AbstractInterceptingMessageProcessorBase

setMuleContext

public void setMuleContext(MuleContext context)

Specified by:

setMuleContext in interface MuleContextAware

Overrides:

setMuleContext in class AbstractInterceptingMessageProcessorBase

setFlowConstruct

public void setFlowConstruct(FlowConstruct flowConstruct)

Specified by:

setFlowConstruct in interface FlowConstructAware

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

start

public void start()
           throws MuleException

Specified by:

start in interface Startable

Throws:

MuleException

stop

public void stop()
          throws MuleException

Specified by:

stop in interface Stoppable

Throws:

MuleException

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.

Specified by:

dispose in interface Disposable
