本文整理了Java中rx.subjects.Subject类的一些代码示例，展示了Subject类的具体用法。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。Subject类的具体详情如下：
包路径：rx.subjects.Subject
类名称：Subject

Subject介绍

[英]Represents an object that is both an Observable and an Observer.
[中]表示既是可观察对象又是观察者的对象。

代码示例

public void write(HystrixCommandExecutionStarted event) {
  writeOnlySubject.onNext(event);
}

代码示例来源：origin: PipelineAI/pipeline

public void shutdown() {
  writeOnlyCommandStartSubject.onCompleted();
  writeOnlyCommandCompletionSubject.onCompleted();
  writeOnlyCollapserSubject.onCompleted();
}

/**
   * 接收消息
   */
  public <T> Observable<T> toObserverable(Class<T> eventType) {
    return bus.ofType(eventType);
  }
}

  .map(value -> {
    System.out.println("Received value " + value);
    new Exception().printStackTrace(System.out);
    return value;
  });
  Observable<Long> timeoutObservable = initialObservable.map(value -> {
    System.out.println("Timeout received value " + value);
    return value;
  });
  TestSubscriber<Long> subscriber = new TestSubscriber<>();
  initialObservable
  .doOnUnsubscribe(() -> System.out.println("Unsubscribed"))
  .timeout(1, TimeUnit.SECONDS, timeoutObservable).subscribe(subscriber);
  subject.onNext(5L);
  Thread.sleep(1500);
  subject.onNext(10L);
  subject.onCompleted();
  subscriber.awaitTerminalEvent();
  subscriber.assertNoErrors();
  subscriber.assertValues(5L, 10L);
}

@Override

  // Schedule timeout once and when not subscribed yet.
