Method Detail

setEndpoint

void setEndpoint(RabbitMQEndpoint endpoint)

Sets the belonging org.apache.camel.component.jms.JmsEndpoint.

setReplyTo

void setReplyTo(String replyTo)

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

The queue is either a temporary or a persistent queue.

registerReply

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

Register a reply

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

setScheduledExecutorService

void setScheduledExecutorService(ScheduledExecutorService executorService)

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

updateCorrelationId

void updateCorrelationId(String correlationId,
                       String newCorrelationId,
                       long requestTimeout)

Updates the correlation id to the new correlation id.

This is only used when useMessageIDasCorrelationID option is used, which means a provisional correlation id is first used, then after the message has been sent, the real correlation id is known. This allows us then to update the internal mapping to expect the real correlation id.

Parameters:

correlationId - the provisional correlation id

newCorrelationId - the real correlation id

requestTimeout - the timeout

processReply

void processReply(ReplyHolder holder)

Process the reply

Parameters:

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