本文整理了Java中io.reactivex.Observable.timeInterval()方法的一些代码示例，展示了Observable.timeInterval()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.timeInterval()方法的具体详情如下：
包路径：io.reactivex.Observable
类名称：Observable
方法名：timeInterval

Observable.timeInterval介绍

[英]Returns an Observable that emits records of the time interval between consecutive items emitted by the source ObservableSource.

Scheduler: timeInterval does not operate on any particular scheduler but uses the current time from the computation Scheduler.
[中]返回一个Observable，该Observable发出源ObservableSource发出的连续项之间的时间间隔记录。
调度器：timeInterval不在任何特定的调度器上运行，而是使用计算调度器中的当前时间。

代码示例

@Override
  public Observable<Timed<Object>> apply(Observable<Object> f)
      throws Exception {
    return f.timeInterval();
  }
