如何从akka演员那里获得消息队列的大小？ [英] how to get the size of message queue from akka actor?

问题描述

应用程序中有Akka（Java API）actor（UntypeActor）和消息。
根据API合同，如果有几条消息发送给同一个演员，它们会被排队并逐个处理。

There are Akka (Java API) actors (UntypeActor) and messages in the application. According to API contract in case a few messages are addressed to the same actor, they are queued and processed with one-by-one.

我是喜欢根据队列大小处理actor中的消息。基本上：在Actor.onReceive（）中处理当前的消息时，是否至少还有一个消息排队？什么是Akka存档的方式？

I'd like to handle messages in the actor depending on queue size. Basically: is there at least one more message queued at the moment current one is handled in Actor.onReceive()? What is the Akka way to archive this?

推荐答案

在你执行的UntypedActor中：

From within the UntypedActor you do:

getContext（）。getMailboxSize（）;

getContext().getMailboxSize();
