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

Indicates each element of a queryable 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, TBufferOpening, TBufferClosing>(
	this IObservable<TSource> source,
	IObservable<TBufferOpening> bufferOpenings,
	Func<TBufferOpening, IObservable<TBufferClosing>> bufferClosingSelector
)

Type Parameters

TSource

The type of source.

TBufferOpening

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

TBufferClosing

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

Parameters

source
Type: System.IObservable<TSource>
The source sequence to produce buffers over.
bufferOpenings
Type: System.IObservable<TBufferOpening>
The observable sequence whose elements denote the creation of new buffers.
bufferClosingSelector
Type: System.Func<TBufferOpening, IObservable<TBufferClosing>>
The function invoked to define the closing of each produced buffer.

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.
