Java Quick Reference - Threads - notify() and notifyAll() methods
|
|
|
|
* the notify() and notifyAll() methods are defined in the Object class
* they can only be used within synchronized code
* notify() wakes up a single thread which is waiting on the object's lock
* if there is more than one thread waiting, the choice is arbitrary ie there is no way to specify which waiting thread should be re-awakened
* notifyAll() wakes up ALL waiting threads; the scheduler decides which one will run
* if there are no waiting threads, the notifys are forgotten
* only notifications that occur after a thread has moved to wait state will effect it; earlier notifies are irrelevant
