software.amazon.disco.agent.event

Class ThreadExitEvent

java.lang.Object

software.amazon.disco.agent.event.AbstractEvent

software.amazon.disco.agent.event.AbstractThreadEvent

software.amazon.disco.agent.event.ThreadExitEvent

All Implemented Interfaces:

Event, ThreadEvent

public class ThreadExitEvent
extends AbstractThreadEvent

Concrete ThreadEvent published when a worker thread exits a Disco transaction, and the inner FunctionalInterface is about to return. Under normal circumstances, a 'ThreadEnterEvent' should always be paired with a 'ThreadExitEvent'. Please note that when an application submits a task, e.g. Runnable to an executor service, e.g. ThreadPoolExecutor, the returned Future object that tracks the completion of the submitted task may be marked as completed before the associated ThreadExitEvent is published. In other words, a call to Future.get() may unblock prior to the publication of the related ThreadExitEvent.
