我在网上找到了这个:http://stackoverflow.com/questions/435069/java-util-concurrentlinkedqueue/435941 // StackOverflow果然是个好地方啊…… 也就是说,如果直接使用它提供的函数,比如:queue.add(obj); 或者 queue.poll(obj);,这样我们自己不需要做任何同步。 但如果是非原子操作,比如: 1. if(!queue.isEmpt...

This implementation employs an efficient non-blocking algorithm based on one described inSimple, Fast, and Practical Non-Blocking and Blocking Concurrent Queue Algorithmsby Maged M. Michael and Michael L. Scott. Iterators areweakly consistent, returning elements reflecting the state of the queue at ...
Hash table and linked list implementation of the Map interface, with well-defined encounter order. C# Copy [Android.Runtime.Register("java/util/LinkedHashMap", DoNotGenerateAcw=true)] [Java.Interop.JavaTypeParameters(new System.String[] { "K", "V" })] public class LinkedHash...
Implementation Note: TheSpliteratorimplementstrySplitto permit limited parallelism. Returns: aSpliteratorover the elements in this queue Since: 1.8 put public void put(Ee) Inserts the specified element at the tail of this queue. As the queue is unbounded, this method will never block. ...
插入元素是追加到尾上。提取一个元素是从头提取。当多个线程共享访问一个公共 collection 时,ConcurrentLinkedQueue 是一个恰当的选择。该队列不允许null元素。 This implementation employs an efficient "wait-free" algorithm based on one described in Simple, Fast, and Practical Non-Blocking and Blocking Concurre...
public classLinkedBlockingQueue<E>extendsAbstractQueue<E> implementsBlockingQueue<E>,Serializable An optionally-boundedblocking queuebased on linked nodes. This queue orders elements FIFO (first-in-first-out). Theheadof the queue is that element that has been on the queue the longest time. Thetail...
