Subject 类的 isStopped 和 closed 属性有什么区别?

问题描述

Subject 类有 2 个属性 closed 和 isStopped.我知道可以使用 closed 来检查 Subject 是否仍然可以订阅，但是 isStopped 究竟应该用于什么?

The class Subject has 2 properties closed and isStopped. I know that closed can be used to check whether the Subject can still be subscribed to, but what should isStopped be used for exactly?

我问这个是因为我试图找到一种方法来知道 BehaviourSubject 的下一个操作何时完成.我可以为此使用 isStopped 还是用于其他用途?

I am asking this because i am trying to find a way to know when a next operation of a BehaviourSubject is completed. Can i use isStopped for that or is it used for something else?

推荐答案

closed 和 isStopped 的比较行为可以从每次操作后的结果值来看:

The compared behavior of closed and isStopped can be seen in terms of resultant values after each operation:

• 出错:
  • 关闭:false
  • isStopped:true.
  • 关闭:false
  • isStopped:true.
  • 关闭:true
  • isStopped: true
