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

Subject.hasThrowable介绍

[英]Returns true if the subject has reached a terminal state through an error event.

The method is thread-safe.
[中]如果主题通过错误事件达到终端状态，则返回true。
该方法是线程安全的。
