public static ObservableAsync<T> RefCount<T>(this ConnectableObservableAsync<T> source)

View source

Summary: Returns an observable sequence that connects to the underlying connectable observable when the first observer subscribes, and disconnects when the last observer unsubscribes.

Type parameters

Name	Description
`T`	The type of the elements in the observable sequence.

Parameters

Name	Type	Description
`source`	[ConnectableObservableAsync](#	The connectable observable sequence to ref count. Cannot be null.

Returns: ObservableAsync -- An observable sequence that stays connected to the source as long as there is at least one subscription.

Remarks

This operator is useful for sharing a single subscription to the underlying connectable observable among multiple subscribers. When the last observer unsubscribes, the connection to the source is automatically disposed.
