SUMMARY: NESTED | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
This interface supports an asynchronous mode of operation.
A reply context has to be provided for callWithReplyContext
methods.
A client that uses these API methods has to create an object that implements the ReplyContext interface so that the process engine knows where to send results to. When a process instance that was started via the callWithReplyContext() API reaches its end, the process engine calls replyProcessResult() or replyException() depending on the result of processing. It is the responsibility of the implementation of this interface to perform the necessary actions in order to inform the caller about the result of processing.
