      • reset

        public void reset()
        Description copied from class: ConnectableObservable
        Resets this ConnectableObservable into its fresh state if it has terminated or has been disposed.

        Calling this method on a fresh or active ConnectableObservable has no effect.

        Scheduler:
        The behavior is determined by the implementor of this abstract class.
        Specified by:
        reset in class ConnectableObservable<T>
      • subscribeActual

        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
      • connect

        public void connect​(Consumer<? super Disposable> connection)
        Description copied from class: ConnectableObservable
        Instructs the ConnectableObservable to begin emitting the items from its underlying Observable to its Observers.
        Scheduler:
        The behavior is determined by the implementor of this abstract class.
        Specified by:
        connect in class ConnectableObservable<T>
        Parameters:
        connection - the action that receives the connection subscription before the subscription to source happens allowing the caller to synchronously disconnect a synchronous source
