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

Observable.ambArray介绍

[英]Mirrors the one ObservableSource in an array of several ObservableSources that first either emits an item or sends a termination notification.

Scheduler: ambArray does not operate by default on a particular Scheduler.
[中]镜像多个可观察资源数组中的一个可观察资源,这些可观察资源首先发出一个项目或发送终止通知。
调度程序:默认情况下,ambArray不会在特定调度程序上运行。
