Recognize one way operation from Destination
Hi,
One transport specific question: are there any way to recognize communication pattern (one-way, request-response) from transport destination at the time when message is received from the network?
Use case: custom transport should send additional confirmation in case of one way operations, but communication pattern cannot be recognized from incoming message.
The question is can destination access implementation class or service interface to check @OneWay annotation for corresponded method? Or is there other solution here?
Regards,
Andrei.

Hi Dan,
Yep, it works.
Thanks,
Andrei.

No. You pretty much have to get at least as far as the initial parsing.

The OneWayProcessorInterceptor will callback on your destination once it knows
that the operation is a OneWay. Thus, at that point, you can handle
whatever cleanup options and such are necessary (or, in the case of HTTP, sent
the 202). This occurs before the call to the service method.
