notifyall

The root Object class includes some special methods for communicating across threads & wait (), notify (), and notifyAll () .

根类Object包含某些特殊的方法，用来在线程的wait（）、notify（）和notifyAll（）之间进行通信。

Careful : replacing the notifyAll () with notify () solves the problem in this scenario but will fail on others !)

注意：用notify（）取代notifyAll（）能解决此情形中的问题，但是在其他情形中将会失败！

The wait () method tells the current thread to go into an inactive state and wait for another thread to call notifyAll () on that object .

wait（）方法将通知当前线程进入非活动状态，并等待另一个线对该对象调用notifyAll（）。

When an external process calls the Bucket 's ( also synchronized ) flush () method , a notifyAll () is sent , thereby waking up all blocking processes .

当外部进程调用Bucket的（也是同步的）flush（）方法时，就发送一个notifyAll（），唤醒所有受阻塞的线程。

The Condition methods that are analogous to wait , notify , and notifyAll , are named await , signal , and signalAll , because they cannot override the corresponding methods in Object .

Condition的方法与wait、notify和notifyAll方法类似，分别命名为await、signal和signalAll，因为它们不能覆盖Object上的对应方法。

In essence , wait () and notify () / notifyAll () act as a simple signaling mechanism , allowing the Drop to coordinate between the Producer and the Consumer threads , one take to each put .

从本质上说，wait（）和notify（）/notifyAll（）允许一种简单的信令机制，它允许Drop在Producer和Consumer线程之间进行协调，每个put都有相应的take。

The first , full access to the underlying libraries ( such as java . util . concurrent ) and support for the " traditional " Java concurrency semantics ( such as monitors and wait () / notifyAll ()) .

首先，对底层库的完全访问（比如说java.util.concurrent）以及对“传统”Java并发性语义的支持（比如说监控程序和wait（）/notifyAll（））。
