Class AsyncResponseHandler

java.lang.Object

org.kie.server.client.jms.AsyncResponseHandler

All Implemented Interfaces:

ResponseHandler

public class AsyncResponseHandler
extends Object
implements ResponseHandler

Async response handler that receives message from response queue using message listener. It requires callback to be invoked upon message delivery otherwise will throw IllegalStateException on runtime.
Due to nature of message listener (cannot clean up its connection and session) another thread is used to perform the cleanup in finally block of message listener.
Response is only delivered via callback thus return value of handleResponse is always single ServiceResponse of type NO_RESPONSE
