Qbservable::Buffer<TSource, TBufferClosing> Method (IQbservable<TSource>, Expression<Func<IObservable<TBufferClosing>>>)

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

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

generic<typename TSource, typename TBufferClosing>
static IQbservable<IList<TSource>^>^ Buffer(
	IQbservable<TSource>^ source, 
	Expression<Func<IObservable<TBufferClosing>^>^>^ bufferClosingSelector

Type Parameters


The type of source.


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


Type: System.Reactive.Linq::IQbservable<TSource>
The source sequence to produce buffers over.
Type: System.Linq.Expressions::Expression<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.Reactive.Linq::IQbservable<IList<TSource>>
The queryable observable sequence of buffers.

Usage Note
