QueuedSynchronizer.apparentlyFirstQueuedIsExclusive介绍

[英]Returns true if the apparent first queued thread, if one exists, is waiting in exclusive mode. If this method returns true, and the current thread is attempting to acquire in shared mode (that is, this method is invoked from TryLockObject#tryAcquireShared) then it is guaranteed that the current thread is not the first queued thread. Used only as a heuristic in ReentrantReadWriteLock.
[中]如果第一个排队线程(如果存在)以独占模式等待,则返回true。如果此方法返回true,并且当前线程正在尝试以共享模式获取(即,此方法从TryLockObject#tryAcquireShared调用),则可以保证当前线程不是第一个排队的线程。仅在ReentranStratedWriteLock中用作启发。
