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

Flowable.skip介绍

[英]Returns a Flowable that skips the first count items emitted by the source Publisher and emits the remainder.

Backpressure: The operator doesn't interfere with backpressure which is determined by the source Publisher's backpressure behavior. Scheduler: This version of skip does not operate by default on a particular Scheduler.
[中]返回一个可流动项,该可流动项跳过源发布服务器发出的第一个计数项,并发出剩余的计数项。
背压:操作员不会干扰由源发布者的背压行为确定的背压。调度程序:默认情况下,此版本的skip不会在特定调度程序上运行。
