如何正确使用AKKA中的pipeTo [英] How to use pipeTo in AKKA correctly

问题描述

我在actor的receive方法中有两个示例：

Hi I have two examples below within the receive method of an actor:

第一个不缓存发送方actor用于管道

First one does not cache the sender actor for piping

val futureV = //Some function call that returns a Future
futureV.pipeTo(sender)

第二个人首先将发件人带入val

Second one takes the sender in a val first

val currentS=sender
val futureV = //Some function call that returns a Future
futureV.pipeTo(currentS)

我的问题是哪种编码方法正确，为什么？

My question is which one is the correct way to code and why?

推荐答案

它们是相同。发件人不会更改。 pipeTo 采用值而不是名称作为参数。

They are the same. The sender is not going to change. pipeTo takes its argument by value, not by name.
