1. Overload¶

public static IQbservable<TResult> Replay<TSource, TResult>(this IQbservable<TSource> source, Expression<Func<IObservable<TSource>, IObservable<TResult>>> selector)

Summary: 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 all notifications. This operator is a specialization of Multicast using a ReplaySubject.

Type parameters

Name	Description
`TSource`	The type of the elements in the source sequence.
`TResult`	The type of the elements in the result sequence.

Parameters

Name	Type	Description
`source`	[IQbservable](#	Source sequence whose elements will be multicasted through a single shared subscription.
`selector`	Expression, IObservable>>	Selector function which can use the multicasted source sequence as many times as needed, without causing multiple subscriptions to the source sequence. Subscribers to the given source will receive all the notifications of the source.

Returns: IQbservable -- An observable sequence that contains the elements of a sequence produced by multicasting the source sequence within a selector function.

Exceptions

Type	Condition
System.ArgumentNullException	`source` or `selector` is null.

`TResult`	The type of the elements in the result sequence.

Parameters

`selector`	Expression, IObservable>>	Selector function which can use the multicasted source sequence as many times as needed, without causing multiple subscriptions to the source sequence. Subscribers to the given source will receive all the notifications of the source subject to the specified replay buffer trimming policy.
`bufferSize`	int	Maximum element count of the replay buffer.

Returns: IQbservable -- An observable sequence that contains the elements of a sequence produced by multicasting the source sequence within a selector function.

Exceptions

Type	Condition
System.ArgumentNullException	`source` or `selector` is null.
