        protected void subscribeActual​(Observer<? super T> observer)
        Description copied from class: Observable
        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 Observable.subscribe(Observer) before this method gets called.

        Specified by:
        subscribeActual in class Observable<T>
        Parameters:
        observer - the incoming Observer, never null

        Returns:
        the value produced
        Throws:
        java.lang.Throwable - if the implementation wishes to throw any type of exception
