prepareExchangeForContinue

protected void prepareExchangeForContinue(org.apache.camel.Exchange exchange,
                                          boolean isDeadLetterChannel)

prepareExchangeForRedelivery

protected void prepareExchangeForRedelivery()

handleException

protected void handleException()

onExceptionOccurred

protected void onExceptionOccurred()

Gives an optional configured OnExceptionOccurred processor a chance to process just after an exception was thrown while processing the Exchange. This allows to execute the processor at the same time the exception was thrown.

deliverToOnRedeliveryProcessor

protected void deliverToOnRedeliveryProcessor()

Gives an optional configured redelivery processor a chance to process before the Exchange will be redelivered. This can be used to alter the Exchange.

deliverToFailureProcessor

protected void deliverToFailureProcessor(org.apache.camel.Processor processor,
                                         boolean isDeadLetterChannel,
                                         org.apache.camel.Exchange exchange)

All redelivery attempts failed so move the exchange to the dead letter queue

prepareExchangeAfterFailure

protected void prepareExchangeAfterFailure(org.apache.camel.Exchange exchange,
                                           boolean isDeadLetterChannel,
                                           boolean shouldHandle,
                                           boolean shouldContinue)

sleep

public boolean sleep()
              throws InterruptedException

This task is for the synchronous blocking. If using async delayed then a scheduled thread pool is used for sleeping and trigger redeliveries.

Throws:

InterruptedException
