Rx.Observable.prototype.shareReplay([bufferSize], [window], [scheduler])

{% if book.isPdf %}

{% else %}

{% endif %}

Returns an observable sequence that shares a single subscription to the underlying sequence replaying notifications subject to a maximum time length for the replay buffer.

This operator is a specialization of replay that connects to the connectable observable sequence when the number of observers goes from zero to one, and disconnects when there are no more observers.

Arguments

1. [bufferSize] (Number): Maximum element count of the replay buffer.
2. [window] (Number): Maximum time length of the replay buffer in milliseconds.
3. [scheduler] (Scheduler): Scheduler where connected observers within the selector function will be invoked on.

Returns

(Observable): An observable sequence that contains the elements of a sequence produced by multicasting the source sequence within a selector function.
