对于 Buffer 等运算符，打开和关闭边界是什么意思? [英] What is the meaning of opening and closing boundaries with regard to operators such as Buffer?

问题描述

我不明白需要打开或关闭边界的 Buffer 运算符的重载.我所指的重载是:

I do not understand the overloads of the Buffer operator that require an opening or closing boundary. The overloads I am refering to are:

public static IObservable<IList<TSource>> Buffer<TSource, 
TBufferClosing>(this IObservable<TSource> source, 
Func<IObservable<TBufferClosing>> bufferClosingSelector)

public static IObservable<IList<TSource>> Buffer<TSource, 
TBufferBoundary>(this IObservable<TSource> source, 
IObservable<TBufferBoundary> bufferBoundaries)

public static IObservable<IList<TSource>> Buffer<TSource, 
TBufferOpening, TBufferClosing>(this IObservable<TSource> source, 
IObservable<TBufferOpening> bufferOpenings, Func<TBufferOpening, 
IObservable<TBufferClosing>> bufferClosingSelector)

能否请您举例说明这些边界的含义?

Could you please explain what the meaning of these boundaries is with an example?

推荐答案

它们等价于 Window 操作符(但每个窗口产生 IList 而不是 IObservable) 记录在这里 - http:///introtorx.com/Content/v1.0.10621.0/17_SequencesOfCoincidence.html

They are equivalent to the Window operators (but each window yields IList<T> instead of IObservable<T>) that are documented here - http://introtorx.com/Content/v1.0.10621.0/17_SequencesOfCoincidence.html

我建议暂停并阅读一些目前在 Rx 上的 doco.这是一个小领域，但有很多小概念.这些的组成是理解它的关键.例如，阅读所有 IntroToRx 需要几个小时(只有 17 页).

I would suggest pausing and reading some of the doco that is currently out there on Rx. It is a small domain, but with lots of little concepts. The composition of these is the key to understanding it. Reading all of IntroToRx for example should take a few hours(it is only 17 pages).
