TaskanaParseListener

BpmnParseListeners can be registered within the engine and are invoked every time the BPMN is parsed by a BpmnParser. This happens when the BPMN is deployed, or when it is loaded from the database for the first time since the engine was started. The BpmnParseListener additionally offers the functionality to parse user tasks to the BpmnParser and add a TaskListener to the given user tasks, solving the problem of having to add the TaskListeners manually.

The TaskanaParseListener makes use of this concept to automatically add a TaskanaTaskListener to all user tasks in every process application.
