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

Syntax

'Declaration
<ExtensionAttribute> _
Public Shared Function Timestamp(Of TSource) ( _
    source As IQbservable(Of TSource), _
    scheduler As IScheduler _
) As IQbservable(Of Timestamped(Of TSource))

'Usage
Dim source As IQbservable(Of TSource)
Dim scheduler As IScheduler
Dim returnValue As IQbservable(Of Timestamped(Of TSource))

returnValue = source.Timestamp(scheduler)

public static IQbservable<Timestamped<TSource>> Timestamp<TSource>(
    this IQbservable<TSource> source,
    IScheduler scheduler
)

[ExtensionAttribute]
public:
generic<typename TSource>
static IQbservable<Timestamped<TSource>>^ Timestamp(
    IQbservable<TSource>^ source, 
    IScheduler^ scheduler
)

static member Timestamp : 
        source:IQbservable<'TSource> * 
        scheduler:IScheduler -> IQbservable<Timestamped<'TSource>> 

JScript does not support generic types and methods.

Type Parameters

• TSource
  The type of source.

Parameters

• source
  Type: System.Reactive.Linq.IQbservable<TSource>
  The source sequence to timestamp values for.

• scheduler
  Type: System.Reactive.Concurrency.IScheduler
  The scheduler used to compute timestamps.

Return Value

Type: System.Reactive.Linq.IQbservable<Timestamped<TSource>>
A queryable observable sequence with timestamp information on values.

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 .
