public void subscribeActual(Observer<? super U> observer)

Implements abstract io.reactivex.Observable.subscribeActual.

Doc from io.reactivex.Observable.subscribeActual.

Operator implementations (both source and intermediate) should implement this method that performs the necessary business logic and handles the incoming Observers.

There is no need to call any of the plugin hooks on the current Observable instance or the Observer; all hooks and basic safeguards have been applied by subscribe(Observer) before this method gets called.

Parameters
observer:Observer<? super U>

the incoming Observer, never null
