- the AsyncCallback
will be invoked when the processing of the exchange is completed.
If the exchange is completed synchronously, then the callback is also invoked synchronously.
The callback should therefore be careful of starting recursive loop.protected Endpoint resolveEndpoint(Exchange exchange, Object recipient)
