Method Detail

setScheduledExecutorService

public void setScheduledExecutorService(ScheduledExecutorService executorService)

Description copied from interface: ReplyManager

Sets the scheduled to use when checking for timeouts (no reply received within a given time period)

Specified by:

setScheduledExecutorService in interface ReplyManager

setEndpoint

public void setEndpoint(JmsEndpoint endpoint)

Description copied from interface: ReplyManager

Sets the belonging JmsEndpoint.

Specified by:

setEndpoint in interface ReplyManager

setReplyTo

public void setReplyTo(javax.jms.Destination replyTo)

Description copied from interface: ReplyManager

Sets the reply to queue the manager should listen for replies.

The queue is either a temporary or a persistent queue.

Specified by:

setReplyTo in interface ReplyManager

getReplyTo

public javax.jms.Destination getReplyTo()

Description copied from interface: ReplyManager

Gets the reply to queue being used

Specified by:

getReplyTo in interface ReplyManager

onMessage

public void onMessage(javax.jms.Message message)

Specified by:

onMessage in interface javax.jms.MessageListener

processReply

public void processReply(ReplyHolder holder)

Description copied from interface: ReplyManager

Process the reply

Specified by:

processReply in interface ReplyManager

Parameters:

holder - containing needed data to process the reply and continue routing

handleReplyMessage

protected abstract void handleReplyMessage(String correlationID,
                                           javax.jms.Message message)

createListenerContainer

protected abstract org.springframework.jms.listener.AbstractMessageListenerContainer createListenerContainer()
                                                                                                      throws Exception

Throws:

Exception

waitForProvisionCorrelationToBeUpdated

protected ReplyHandler waitForProvisionCorrelationToBeUpdated(String correlationID,
                                                              javax.jms.Message message)

IMPORTANT: This logic is only being used due to high performance in-memory only testing using InOut over JMS. Its unlikely to happen in a real life situation with communication to a remote broker, which always will be slower to send back reply, before Camel had a chance to update it's internal correlation map.

doStop

protected void doStop()
