ReplyManagerSupport

public ReplyManagerSupport(org.apache.camel.CamelContext camelContext)

Method Detail

setScheduledExecutorService

public void setScheduledExecutorService(ScheduledExecutorService executorService)

Description copied from interface: ReplyManager

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

Specified by:

setScheduledExecutorService in interface ReplyManager

setOnTimeoutExecutorService

public void setOnTimeoutExecutorService(ExecutorService executorService)

Description copied from interface: ReplyManager

Sets the thread pool to use for continue routing Exchange when a timeout was triggered when doing request/reply over JMS.

Specified by:

setOnTimeoutExecutorService 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

setCorrelationProperty

public void setCorrelationProperty(String correlationProperty)

Description copied from interface: ReplyManager

Sets the JMS message property used for message correlation. If set message correlation will be performed on the value of this JMS property, JMSCorrelationID will be ignored.

Specified by:

setCorrelationProperty 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

registerReply

public String registerReply(ReplyManager replyManager,
                            org.apache.camel.Exchange exchange,
                            org.apache.camel.AsyncCallback callback,
                            String originalCorrelationId,
                            String correlationId,
                            long requestTimeout)

Description copied from interface: ReplyManager

Register a reply

Specified by:

registerReply in interface ReplyManager

Parameters:

replyManager - the reply manager being used

exchange - the exchange

callback - the callback

originalCorrelationId - an optional original correlation id

correlationId - the correlation id to expect being used

requestTimeout - the timeout

Returns:

the correlation id used

createReplyHandler

protected abstract ReplyHandler createReplyHandler(ReplyManager replyManager,
                                                   org.apache.camel.Exchange exchange,
                                                   org.apache.camel.AsyncCallback callback,
                                                   String originalCorrelationId,
                                                   String correlationId,
                                                   long requestTimeout)

onMessage

public void onMessage(javax.jms.Message message,
                      javax.jms.Session session)
               throws javax.jms.JMSException

Specified by:

onMessage in interface org.springframework.jms.listener.SessionAwareMessageListener

Throws:

javax.jms.JMSException

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,
                                           javax.jms.Session session)

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.
