Observable.Buffer<TSource> Method (IObservable<TSource>, TimeSpan, IScheduler)

Indicates each element of an observable sequence into consecutive non-overlapping buffers which are produced based on timing information.

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

Syntax

'Declaration
<ExtensionAttribute> _
Public Shared Function Buffer(Of TSource) ( _
    source As IObservable(Of TSource), _
    timeSpan As TimeSpan, _
    scheduler As IScheduler _
) As IObservable(Of IList(Of TSource))

'Usage
Dim source As IObservable(Of TSource)
Dim timeSpan As TimeSpan
Dim scheduler As IScheduler
Dim returnValue As IObservable(Of IList(Of TSource))

returnValue = source.Buffer(timeSpan, _
    scheduler)

public static IObservable<IList<TSource>> Buffer<TSource>(
    this IObservable<TSource> source,
    TimeSpan timeSpan,
    IScheduler scheduler
)

[ExtensionAttribute]
public:
generic<typename TSource>
static IObservable<IList<TSource>^>^ Buffer(
    IObservable<TSource>^ source, 
    TimeSpan timeSpan, 
    IScheduler^ scheduler
)

static member Buffer : 
        source:IObservable<'TSource> * 
        timeSpan:TimeSpan * 
        scheduler:IScheduler -> IObservable<IList<'TSource>> 

JScript does not support generic types and methods.

Type Parameters

• TSource
  The type source.

Parameters

• source
  Type: System.IObservable<TSource>
  The source sequence to produce buffers over.

• timeSpan
  Type: System.TimeSpan
  The length of each buffer.

• scheduler
  Type: System.Reactive.Concurrency.IScheduler
  The scheduler to run buffering timers on.

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 .
