public class WireTap
extends AbstractMessageProcessorOwner
implements Processor

The WireTap MessageProcessor allows inspection of messages in a flow.

The incoming message is is sent to both the primary and wiretap outputs. The flow of the primary output will be unmodified and a copy of the message used for the wiretap output.

An optional filter can be used to filter which message are sent to the wiretap output, this filter does not affect the flow to the primary output. If there is an error sending to the wiretap output no exception will be thrown but rather an error logged.
