Actor clean up #33

Open He-Pin opened 7 years ago

He-Pin commented 7 years ago

我有个问题请教下。父actor，可能会创建n多的子actor，但是子actor太多的话，会导致占用内存太多，有没有办法，让没有用到的子actor过一段时间就自动从内存中清除掉?

Ryan-Cui commented 7 years ago

如何判断（或如何得知）一个Actor在内存中是没有用到的呢？

He-Pin commented 7 years ago

@Ryan-Cui 一般的做法都是通过设置接收消息超时来做的，即setReceiveTimeout

http://doc.akka.io/docs/akka/current/scala/actors.html#Receive_timeout

如果一段时间内没有收到消息，就关掉自己，即调用stop(self).
