public class SizeBlockingQueue<E>
extends java.util.AbstractQueue<E>
implements java.util.concurrent.BlockingQueue<E>
A size based queue wrapping another blocking queue to provide (somewhat relaxed) capacity checks. Mainly makes sense to use with blocking queues that are unbounded to provide the ability to do capacity verification.
