public class ByteBufferQueueInputStream
extends InputStream

An InputStream backed by a ByteBufferQueue. Assumes that the backing ByteBufferQueue will not be updated by another thread during calls to read() so all methods are non-blocking and an empty ByteBufferQueue is deemed equivalent to end of stream.
