Interface ThreadsListener

public interface ThreadsListener
Listener to be notified about changes of threads in guest language application.

Use Instrumenter.attachThreadsListener(com.oracle.truffle.api.instrumentation.ThreadsListener, boolean) to register an implementation of this listener. Use EventBinding.dispose() to unregister.

The listener gets called when a thread is initialized for use in a context or thread-related resources are disposed in a context. The notification calls do not say anything about the actual life-time of the thread as such, which may live before the initialization and may continue to live after the disposal.
