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

Notification.isOnNext介绍

[英]Returns true if this notification is an onNext signal and #getValue() returns the contained value.
[中]如果此通知是onNext信号，则返回true，#getValue（）返回包含的值。
