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

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.

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

static member Replay : 
        source:IQbservable<'TSource> * 
        selector:Expression<Func<IObservable<'TSource>, IObservable<'TResult>>> * 
        bufferSize:int * 
        scheduler:IScheduler -> IQbservable<'TResult> 

Type Parameters

TSource

The type of source.

TResult

The type of result.

Parameters

source
Type: System.Reactive.Linq.IQbservable(TSource)
The source sequence whose elements will be multicasting through a single shared subscription.
selector
Type: System.Linq.Expressions.Expression(Func(IObservable(TSource), IObservable(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.
scheduler
Type: System.Reactive.Concurrency.IScheduler
The scheduler where connected observers within the selector function will be invoked on.

Return Value

Type: System.Reactive.Linq.IQbservable(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(TSource). When you use instance method syntax to call this method, omit the first parameter.
