Observable::Replay<TSource, TResult> Method (IObservable<TSource>, Func<IObservable<TSource>, IObservable<TResult>>, Int32)

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

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

[ExtensionAttribute]
public:
generic<typename TSource, typename TResult>
static IObservable<TResult>^ Replay(
	IObservable<TSource>^ source, 
	Func<IObservable<TSource>^, IObservable<TResult>^>^ selector, 
	int bufferSize
)

Type Parameters

TSource

The type of source.

TResult

The type of result.

Parameters

source
Type: System::IObservable<TSource>
The source sequence whose elements will be multicasted through a single shared subscription.
selector
Type: System::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.

Return Value

Type: System::IObservable<TResult>
An 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 IObservable<TSource>. When you use instance method syntax to call this method, omit the first parameter.
