Interface AsyncCallback

All Superinterfaces:
Runnable
public interface AsyncCallback extends Runnable
The callback interface for an AsyncProcessor so that it can notify you when an Exchange is done.

For example a AsyncProcessor should invoke the done method when the Exchange is ready to be continued routed. This allows to implement asynchronous Producer which can continue routing Exchange when all the data has been gathered. This allows to build non blocking request/reply communication.
