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

Observable.singleOrError介绍

[英]Returns a Single that emits the single item emitted by this Observable if this Observable emits only a single item, otherwise if this Observable completes without emitting any items or emits more than one item a NoSuchElementException or IllegalArgumentException will be signalled respectively.

Scheduler: singleOrError does not operate by default on a particular Scheduler.
[中]如果此可观测对象仅发射单个项，则返回发射此可观测对象发射的单个项的单个项；否则，如果此可观测对象在未发射任何项的情况下完成，或发射多个项，则将分别发出NosTouchElementException或IllegalArgumentException信号。
调度程序：默认情况下，singleOrError不会在特定调度程序上运行。
