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

Observable.error介绍

[英]Returns an Observable that invokes an Observer's Observer#onError method when the Observer subscribes to it.

Scheduler: error does not operate by default on a particular Scheduler.
[中]返回一个Observable，当观察者订阅它时，它调用观察者的Observator#onError方法。
计划程序：默认情况下，错误不会在特定计划程序上运行。
