public class BoundedPriorityBlockingQueue<E>
extends AbstractQueue<E>
implements BlockingQueue<E>

A generic bounded blocking Priority-Queue. The elements of the priority queue are ordered according to the Comparator provided at queue construction time. If multiple elements have the same priority this queue orders them in FIFO (first-in-first-out) manner. The head of this queue is the least element with respect to the specified ordering. If multiple elements are tied for least value, the head is the first one inserted. The queue retrieval operations poll, remove, peek, and element access the element at the head of the queue.
