Class Queue

java.lang.Object
  net.pakl.rl.Queue

public class Queue
extends java.lang.Object

This class is a synchronized queue (FIFO) data structure. It is often used to transfer objects between threads. NB: Do NOT attempt code like: if(!queue.isEmpty()) foo = queue.get(); It is not thread-safe, even though isEmpty() and get() are synchronized. It is possible for a thread to sneak in after the call to isEmpty() and before the call to get(). If you must do this, use something like: synchronized(queue) { if(!queue.isEmpty()) foo.queue.get(); } The same applies to using size() and get().
