Qbservable.Replay<TSource, TResult> Method (IQbservable<TSource>, Expression<Func<IObservable<TSource>, IObservable<TResult>>>, 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 all notifications within window.
Assembly: System.Reactive.Providers (in System.Reactive.Providers.dll)
public static IQbservable<TResult> Replay<TSource, TResult>( this IQbservable<TSource> source, Expression<Func<IObservable<TSource>, IObservable<TResult>>> selector, TimeSpan window )
The type of source.
The type of result.
- Type: System.Reactive.Linq.IQbservable<>
The source sequence whose elements will be multicasting through a single shared subscription.
- Type: System.Linq.Expressions.Expression<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.TimeSpan
The maximum time length of the replay buffer.
Return ValueType: System.Reactive.Linq.IQbservable<>
A queryable observable sequence that contains the elements of a sequence produced by multicasting the source sequence within a selector function.
