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

Observable.blockingIterable介绍

[英]Converts this Observable into an Iterable.

Scheduler: blockingIterable does not operate by default on a particular Scheduler.
[中]将此可观察项转换为可观察项。
调度器：blockingIterable默认情况下不会在特定的调度器上运行。

代码示例

    return v;
  }
})
