What is java's equivalent of ManualResetEvent?

推荐答案

最近我所知道的是的Semaphore 。只需将其与许可证的1计数，并AQUIRE /释放将是pretty的一样一样的，你知道从什么的ManualResetEvent 。

The closest I know of is the Semaphore. Just use it with a "permit" count of 1, and aquire/release will be pretty much the same as what you know from the ManualResetEvent.

一个信号量初始化为1，和   这是用来使得其只具有   最为一个可用的许可，可以为   作为一个互斥锁定。这是   通常被称为二进制   信号量，因为它仅具有两个   声明：可用的一个许可证，或零   可用许可。如果在此使用   方式中，二进制信号具有   属性（与很多Lock   实现），即锁定即可   由线程比其他被释放   所有者（如信号灯有没有概念   所有权）。这可以在一些有用   专门的上下文如死锁   恢复。

A semaphore initialized to one, and which is used such that it only has at most one permit available, can serve as a mutual exclusion lock. This is more commonly known as a binary semaphore, because it only has two states: one permit available, or zero permits available. When used in this way, the binary semaphore has the property (unlike many Lock implementations), that the "lock" can be released by a thread other than the owner (as semaphores have no notion of ownership). This can be useful in some specialized contexts, such as deadlock recovery.
