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

Observable.unsafeCreate介绍

[英]Create an Observable by wrapping an ObservableSource which has to be implemented according to the Reactive-Streams-based Observable specification by handling cancellation correctly; no safeguards are provided by the Observable itself. Scheduler: unsafeCreate by default doesn't operate on any particular Scheduler.
[中]通过包装ObservableSource创建一个Observable，该ObservableSource必须根据基于反应流的Observable规范通过正确处理取消来实现；可观察物体本身不提供任何保护措施*。调度程序：默认情况下，未完成处理不会在任何特定调度程序上运行。
