Class InvokerMessageProcessor

java.lang.Object

org.mule.AbstractAnnotatedObject

org.mule.processor.InvokerMessageProcessor

All Implemented Interfaces:

AnnotatedObject, MuleContextAware, Initialisable, MessageProcessor

public class InvokerMessageProcessor
extends AbstractAnnotatedObject
implements MessageProcessor, Initialisable, MuleContextAware

InvokerMessageProcessor invokes a specified method of an object. An array of argument expressions can be provided to map the message to the method arguments. The method used is determined by the method name along with the number of argument expressions provided. The results of the expression evaluations will automatically be transformed where possible to the method argument type. Multiple methods with the same name and same number of arguments are not supported currently.

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

resolveMethodToInvoke

protected void resolveMethodToInvoke()
                              throws InitialisationException

Throws:

InitialisationException

lookupObjectInstance

protected void lookupObjectInstance()
                             throws InitialisationException

Throws:

InitialisationException

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

Throws:

MuleException

evaluateArguments

protected Object[] evaluateArguments(MuleEvent event,
                         List<?> argumentTemplates)
                              throws MessagingException

Throws:

MessagingException

evaluateExpressionCandidate

protected Object evaluateExpressionCandidate(Object expressionCandidate,
                                 MuleMessage message)
