主题vs AnonymousSubject [英] Subject vs AnonymousSubject

问题描述

RxJS 5 中主题和 AnonymousSubject 之间的区别是什么？
我在互联网上搜索但没有找到任何关于 AnonymousSubject 的信息。

What's the difference between Subject and AnonymousSubject in RxJS 5? I've searched the internet but didn't find any info about AnonymousSubject.

我'在网上找到了一个例子

I've found an example on the web

Subject.create(observer, observable);

查看rxjs源代码我看到这创建了 AnonymousSubject 。
你能想出一个好用的例子 AnonymousSubject ？

Looking into rxjs source code I saw that this creates and AnonymousSubject. Can you also come up with an example when is good to use AnonymousSubject?

推荐答案

AnonymousSubject 不会订阅源Observable。它只是连接来源和目的地。

The AnonymousSubject doesn't subscribe itself to the source Observable. It just connects the source and destination.

我不知道 AnonymousSubject 的典型用例是什么样的，但它在 Subject.lift（） 。

I don't know what a typical use-case for AnonymousSubject looks like but it's used inside Subject.lift().

另见： RxJs Subject.subscribe方法无法按预期工作
