/**@class java.util.concurrent.LinkedBlockingQueue implements java.util.concurrent.BlockingQueue implements java.io.Serializable @extends java.util.AbstractQueue An optionally-bounded {@linkplain java.util.concurrent.BlockingQueue blocking queue} based on linked nodes. This queue orders elements FIFO (first-in-first-out). The <em>head</em> of the queue is that element that has been on the queue the longest time. The <em>tail</em> of the queue is that element that has been on the queue the shortest time. New elements are inserted at the tail of the queue, and the queue retrieval operations obtain elements at the head of the queue. Linked queues typically have higher throughput than array-based queues but less predictable performance in most concurrent applications. <p>The optional capacity bound constructor argument serves as a way to prevent excessive queue expansion. The capacity, if unspecified, is equal to {@link Integer#MAX_VALUE}. Linked nodes are dynamically created upon each insertion unless this would bring the queue above capacity. <p>This class and its iterator implement all of the <em>optional</em> methods of the {@link Collection} and {@link Iterator} interfaces. @since 1.5 @author Doug Lea @param <E> the type of elements held in this queue */ var LinkedBlockingQueue = { /**Returns the number of elements in this queue. @return {Number} the number of elements in this queue */ size : function( ) {}, /**Returns the number of additional elements that this queue can ideally (in the absence of memory or resource constraints) accept without blocking.
