Public Shared Function Buffer(Of TSource, TBufferClosing) ( _

'Usage

[ExtensionAttribute]
public:

Func<IObservable<TBufferClosing>^>^ bufferClosingSelector
)
static member Buffer :

JScript does not support generic types and methods.
Type Parameters
- TSource
The type of source.
- 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.
- bufferClosingSelector
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. For more information, see or .
