Question

我目前正在为当前项目选择RxJava 1.x或2.x.

我基本上需要$ PATH=/usr/local/bin:/usr/bin:/bin sanitize_PATH PATH=/usr/local/bin:/usr/bin:/bin $ PATH=:/usr/local/bin:/usr/bin:/bin sanitize_PATH dropping from PATH: '' PATH=/usr/local/bin:/usr/bin:/bin $ PATH=/usr/local/bin:/usr/bin:/bin: sanitize_PATH dropping from PATH: '' PATH=/usr/local/bin:/usr/bin:/bin $ PATH=/usr/local/bin:/usr/bin:/bin: sanitize_PATH dropping from PATH: '' PATH=/usr/local/bin:/usr/bin:/bin $ PATH=.:bin:/usr/local/bin:/usr/bin:/bin sanitize_PATH dropping from PATH: '.' dropping from PATH: 'bin' PATH=/usr/local/bin:/usr/bin:/bin $ PATH=/usr/local/bin::/usr/bin:/bin sanitize_PATH dropping from PATH: '' PATH=/usr/local/bin:/usr/bin:/bin背压策略PublishSubject。

我想选择RxJava 2.x，但我不能完全理解如何将背压策略应用于onBackpressureLatest()，因为它继承自PublishSubject而不是Observable {1}}。

您能告诉我如何在RxJava 2.x中创建Flowable背压策略PublishSubject吗？

Answer 1

在2.x中，背压被移动到基本类型Flowable及其热门合作伙伴PublishProcessor，ReplayProcessor等。

PublishProcessor<Integer> pp = PublishProcessor.create();
Flowable<Integer> out = pp.onBackpressureLatest();

Answer 2

我在某些时候使用过这样的东西：

Subject<Object> emitterSubject = PublishSubject.<Object>create().toSerialized();

emitterSubject.toFlowable(BackpressureStrategy.LATEST)

在RxJava 2.x中发布具有背压的主题
