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.
Assembly: System.Reactive (in System.Reactive.dll)
public static IObservable<TResult> Replay<TSource, TResult>( this IObservable<TSource> source, Func<IObservable<TSource>, IObservable<TResult>> selector, int bufferSize )
The type of source.
The type of result.
- Type: System.IObservable<>
The source sequence whose elements will be multicasted through a single shared subscription.
- Type: System.Func<IObservable<>, IObservable<>>
The selector function which can use the multicasted source sequence as many times as needed, without causing multiple subscriptions to the source sequence.
- Type: System.Int32
The maximum element count of the replay buffer.
Return ValueType: System.IObservable<>
An observable sequence that contains the elements of a sequence produced by multicasting the source sequence within a selector function.
