Qbservable.Replay(TSource, TResult) Method (IQbservable(TSource), Expression(Func(IObservable(TSource), IObservable(TResult))), TimeSpan, 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 all notifications within window.
Assembly: System.Reactive.Providers (in System.Reactive.Providers.dll)
static member Replay : source:IQbservable<'TSource> * selector:Expression<Func<IObservable<'TSource>, IObservable<'TResult>>> * window:TimeSpan * scheduler:IScheduler -> IQbservable<'TResult>
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.
- Type: System.Reactive.Concurrency.IScheduler
The scheduler where connected observers within the selector function will be invoked on.
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.
