Class NotifyThread

java.lang.Object

java.lang.Thread

ptolemy.actor.process.NotifyThread

All Implemented Interfaces:

java.lang.Runnable

public class NotifyThread
extends java.lang.Thread

Helper thread for calling notifyAll() on a single lock or a LinkedList of locks. Since this is a new thread without any locks, calling notifyAll from this thread reduces the possibility of deadlocks.

To use this to wake up any threads waiting on a lock, create a new instance of this class with a LinkedList of lock objects (or single lock) to call notifyAll() on.
