使用Actors而不是`synchronized' [英] Using Actors instead of `synchronized`

问题描述

每次我阅读关于在Scala中使用同步时，作者通常会提到应该使用Actors（例如）。虽然我大致了解演员的工作，我真的想看到的演员被用来替换Java的同步方法修改器的一个例子（这里我的意思是它的Scala等效 - code> synchronized block）。修改数据结构的内部实例将是很高兴看到。

Every time I read about using synchronized in Scala the author will usually mention that Actors should be used instead (this for example). While I understand roughly how actors work I'd really like to see an example of Actors being used to replace Java's synchronized method modifier (by this I mean its Scala equivalent - the synchronized block) in a piece of code. Modifying the internals of a data structure for instance would be nice to see.

这是对演员的好用还是我误导了？

Is this a good use of Actors or have I been misinformed?

推荐答案

Actor保证只有一个消息在时间处理，所以不会有两个线程访问任何实例成员 - ergo不需要使用synchronized

Actors guarantee that only a single message will be handles at time so that there will not be two threads accessing any of the instance members - ergo no need to use synchronized
