Buffer(TSource, TBufferClosing) Method (IObservable(TSource), Func(IObservable(TBufferClosing)))

Observable.Buffer<TSource, TBufferClosing> Method (IObservable<TSource>, Func<IObservable<TBufferClosing>>)

Indicates each element of an observable sequence into consecutive non-overlapping buffers.

Namespace:  System.Reactive.Linq
Assembly:  System.Reactive (in System.Reactive.dll)

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

Type Parameters


The type of source.


The type of observable sequence whose elements denote the closing of each produced buffer.


Type: System.IObservable<TSource>
The source sequence to produce buffers over.
Type: System.Func<IObservable<TBufferClosing>>
A function invoked to define the boundaries of the produced buffers. A new buffer is started when the previous one is closed.

Return Value

Type: System.IObservable<IList<TSource>>
The observable sequence of buffers.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IObservable<TSource>. When you use instance method syntax to call this method, omit the first parameter.
