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)

Syntax

'Declaration
<ExtensionAttribute> _
Public Shared Function Buffer(Of TSource, TBufferClosing) ( _
    source As IQbservable(Of TSource), _
    bufferClosingSelector As Expression(Of Func(Of IObservable(Of TBufferClosing))) _
) As IQbservable(Of IList(Of TSource))

'Usage
Dim source As IQbservable(Of TSource)
Dim bufferClosingSelector As Expression(Of Func(Of IObservable(Of TBufferClosing)))
Dim returnValue As IQbservable(Of IList(Of TSource))

returnValue = source.Buffer(bufferClosingSelector)

[ExtensionAttribute]
public:

static IQbservable<IList<TSource>^>^ Buffer(
    IQbservable<TSource>^ source,

JScript does not support generic types and methods.

Type Parameters

• TSource
  The type of source.

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

Parameters

• source
  Type: System.Reactive.Linq.IQbservable<TSource>
  The source sequence to produce buffers over.

• bufferClosingSelector
  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

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

Type Parameters

• TSource
  The type of source.

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

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

Parameters

• source
  Type: System.Reactive.Linq.IQbservable<TSource>
  The source sequence to produce buffers over.

• bufferOpenings
  Type: System.IObservable<TBufferOpening>
  The queryable observable sequence whose elements denote the creation of new buffers.

• bufferClosingSelector
  Type: System.Linq.Expressions.Expression<Func<TBufferOpening, IObservable<TBufferClosing>>>
  The function invoked to define the closing of each produced buffer.

Return Value

Type: System.Reactive.Linq.IQbservable<IList<TSource>>
The queryable observable sequence of buffers.
