/**@class java.util.concurrent.DelayQueue implements java.util.concurrent.BlockingQueue @extends java.util.AbstractQueue An unbounded {@linkplain java.util.concurrent.BlockingQueue blocking queue} of {@code Delayed} elements, in which an element can only be taken when its delay has expired. The <em>head</em> of the queue is that {@code Delayed} element whose delay expired furthest in the past. If no delay has expired there is no head and {@code poll} will return {@code null}. Expiration occurs when an element's {@code getDelay(TimeUnit.NANOSECONDS)} method returns a value less than or equal to zero. Even though unexpired elements cannot be removed using {@code take} or {@code poll}, they are otherwise treated as normal elements. For example, the {@code size} method returns the count of both expired and unexpired elements. This queue does not permit null elements. <p>This class and its iterator implement all of the <em>optional</em> methods of the {@link Collection} and {@link Iterator} interfaces. The Iterator provided in method {@link #iterator}() is <em>not</em> guaranteed to traverse the elements of the DelayQueue in any particular order. @since 1.5 @author Doug Lea @param <E> the type of elements held in this queue */ var DelayQueue = { /**Inserts the specified element into this delay queue. @param {Object {Delayed}} e the element to add @return {Boolean} {@code true} (as specified by {@link Collection#add}) @throws NullPointerException if the specified element is null */ add : function( ) {}, /**Inserts the specified element into this delay queue. @param {Object {Delayed}} e the element to add @return {Boolean} {@code true} @throws NullPointerException if the specified element is null */ offer : function( ) {}, /**Inserts the specified element into this delay queue.
