Qbservable.Replay(Of TSource, TResult) Method (IQbservable(Of TSource), Expression(Of Func(Of IObservable(Of TSource), IObservable(Of TResult))), Int32, TimeSpan)

Returns a queryable observable sequence that is the result of invoking the selector on a connectable queryable observable sequence that shares a single subscription to the underlying sequence replaying bufferSize notifications within window.

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

'Declaration
<ExtensionAttribute> _
Public Shared Function Replay(Of TSource, TResult) ( _
	source As IQbservable(Of TSource), _
	selector As Expression(Of Func(Of IObservable(Of TSource), IObservable(Of TResult))), _
	bufferSize As Integer, _
	window As TimeSpan _
) As IQbservable(Of TResult)
'Usage
Dim source As IQbservable(Of TSource)
Dim selector As Expression(Of Func(Of IObservable(Of TSource), IObservable(Of TResult)))
Dim bufferSize As Integer
Dim window As TimeSpan
Dim returnValue As IQbservable(Of TResult)

returnValue = source.Replay(selector, _
	bufferSize, window)

Type Parameters

TSource

The type of source.

TResult

The type of result.

Parameters

source
Type: System.Reactive.Linq.IQbservable(Of TSource)
The source sequence whose elements will be multicasting through a single shared subscription.
selector
Type: System.Linq.Expressions.Expression(Of Func(Of IObservable(Of TSource), IObservable(Of TResult)))
The selector function which can use the multicasted source sequence as many times as needed, without causing multiple subscriptions to the source sequence.
bufferSize
Type: System.Int32
The maximum element count of the replay buffer.
window
Type: System.TimeSpan
The maximum time length of the replay buffer.

Return Value

Type: System.Reactive.Linq.IQbservable(Of TResult)
A queryable observable sequence that contains the elements of a sequence produced by multicasting the source sequence within a selector function.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IQbservable(Of TSource). When you use instance method syntax to call this method, omit the first parameter.
