| EventSubscriber | | public interface EventSubscriber extends WfObject(Code) | | An EventSubscriber represents a connection to the
workflow engine's event queue. From its creation with
WorkflowService.createEventSubscriberWorkflowService.createEventSubscriber until its
destruction with
WorkflowService.releaseWorkflowService.release all events from the workflow
engine are delivered to the EventSubscriber.
EventSubscribers should be released using
WorkflowService.release WorkflowService.release when
no longer needed as they may consume considerable resources.
