rxjs 5 中的发布和多播运算符有什么区别? [英] What's the difference between publish and multicast operator in rxjs 5?

问题描述

我正在阅读 rxjs 手册，我对多播和发布操作符之间的区别有点困惑.它们看起来非常相似.

I'm reading the rxjs manual, I'm a little confused about what's the difference between multicast and publish operators. They seem very similar.

推荐答案

我在阅读 http://reactivex.io/rxjs/manual/overview.html.所以要说清楚，.publish() 只是 .multicast(new Rx.Subject())(和 publishBehavior，publishLast 和 publishReplay 类似，但分别实例化了 BehaviorSubject、AsyncSubject 和 ReplaySubject).

I had the same question when reading http://reactivex.io/rxjs/manual/overview.html. So to make it clear, .publish() is just shorthand for .multicast(new Rx.Subject()) (and publishBehavior, publishLast, and publishReplay are similar but instantiate BehaviorSubject, AsyncSubject and ReplaySubject respectively).
