All Implemented Interfaces:

Iterable<E>, Collection<E>, BlockingQueue<E>, Queue<E>

public abstract class BytesBoundedLinkedQueue<E>
extends AbstractQueue<E>
implements BlockingQueue<E>

Abstract implementation of a BlockingQueue bounded by the size of elements, works similar to LinkedBlockingQueue except that capacity is bounded by the size in bytes of the elements in the queue.
