本文整理了Java中io.reactivex.Observable.doOnTerminate()方法的一些代码示例，展示了Observable.doOnTerminate()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Observable.doOnTerminate()方法的具体详情如下：
包路径：io.reactivex.Observable
类名称：Observable
方法名：doOnTerminate

Observable.doOnTerminate介绍

[英]Modifies the source ObservableSource so that it invokes an action when it calls onComplete or onError.

This differs from doAfterTerminate in that this happens before the onComplete or onError notification. Scheduler: doOnTerminate does not operate by default on a particular Scheduler.
[中]修改源ObservableSource，以便在调用onComplete或onError时调用操作。
这与doAfterTerminate的不同之处在于，这发生在onComplete或onError通知之前。调度器：默认情况下，DooInterminate不会在特定的调度器上运行。

@Test(expected = NullPointerException.class)
public void doOnTerminatedNull() {
  just1.doOnTerminate(null);
}

代码示例来源：origin: ReactiveX/RxJava

@Test
public void doOnTerminateComplete() {
  final AtomicBoolean r = new AtomicBoolean();
  String output = Observable.just("one").doOnTerminate(new Action() {
    @Override
    public void run() {
      r.set(true);
    }
  }).blockingSingle();
  assertEquals("one", output);
  assertTrue(r.get());
}
