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

Observable.delay介绍

[英]Returns an Observable that emits the items emitted by the source Observable shifted forward in time by a specified delay. Error notifications from the source Observable are not delayed.

Scheduler: This version of delay operates by default on the compuation Scheduler.
[中]返回一个Observable，该Observable发出源Observable发出的项，该源Observable在时间上向前移动了指定的延迟。来自可观测源的错误通知不会延迟。
调度程序：默认情况下，此版本的延迟在计算调度程序上运行。
