public class BlockingArrayQueue<E>
extends AbstractList<E>
implements BlockingQueue<E>

Deprecated.

The Eclipse Jetty and Apache Felix Http Jetty packages are no longer supported.

A BlockingQueue backed by a circular array capable or growing.

This queue is uses a variant of the two lock queue algorithm to provide an efficient queue or list backed by a growable circular array.

Unlike ArrayBlockingQueue, this class is able to grow and provides a blocking put call.

The queue has both a capacity (the size of the array currently allocated) and a max capacity (the maximum size that may be allocated), which defaults to Integer.MAX_VALUE.
