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

Observable.toSortedList介绍

[英]Returns an Observable that emits a list that contains the items emitted by the source Observable, in a sorted order. Each item emitted by the Observable must implement Comparable with respect to all other items in the sequence.

Backpressure Support: This operator does not support backpressure as by intent it is requesting and buffering everything. Scheduler: toSortedList does not operate by default on a particular Scheduler.
[中]返回一个Observable，该Observable发出一个列表，其中包含源Observable按排序顺序发出的项。可观察物发出的每个项目必须与序列中的所有其他项目具有可比性。
背压支持：该操作员无意支持背压，因为它正在请求和缓冲所有内容。Scheduler:toSortedList默认情况下不会在特定的计划程序上运行。
