public abstract class AbstractRequestResponseMessageProcessor
extends AbstractInterceptingMessageProcessor
implements NonBlockingSupported

Base implementation of a MessageProcessor that may performs processing during both the request and response processing phases while supporting non-blocking execution.

In order to define the process during the request phase you should override the processRequest(org.mule.api.MuleEvent) method. Symmetrically, if you need to define a process to be executed during the response phase, then you should override the processResponse(org.mule.api.MuleEvent) method.

In some cases you'll have some code that should be always executed, even if an error occurs, for those cases you should override the processFinally(org.mule.api.MuleEvent, org.mule.api.MessagingException) method.

Method Detail

process

public final 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

Throws:

MuleException

processBlocking

protected MuleEvent processBlocking(MuleEvent event)
                             throws MuleException

Throws:

MuleException

processNonBlocking

protected MuleEvent processNonBlocking(MuleEvent event)
                                throws MuleException

Throws:

MuleException

createReplyToHandler

protected ReplyToHandler createReplyToHandler(MuleEvent event)

processRequest

protected MuleEvent processRequest(MuleEvent event)
                            throws MuleException

Processes the request phase before the next message processor is invoked.

Parameters:

event - event to be processed.

Returns:

result of request processing.

Throws:

MuleException - exception thrown by implementations of this method whiile performing response processing

processResponse

protected MuleEvent processResponse(MuleEvent event)
                             throws MuleException

Processes the response phase after the next message processor and it's response phase have been invoked

Parameters:

event - event to be processed.

Returns:

result of response processing.

Throws:

MuleException - exception thrown by implementations of this method whiile performing response processing

processFinally

protected void processFinally(MuleEvent event,
                  MessagingException exception)

Used to perform post processing after both request and response phases have been completed. This method will be invoked both when processing is successful as well as if an exception is thrown. successful result and in the case of an exception being thrown.

Parameters:

event - the result of request and response processing. Note that this includes the request and response processing of the rest of the Flow following this message processor too.

exception - the exception thrown during processing if any. If not exception was thrown then this parameter is null
