Observer

trait Observer[-T] extends AnyRef

Provides a mechanism for receiving push-based notifications.

After an Observer calls an rxscalajs.Observable's subscribe method, the Observable calls the Observer's onNext method to provide notifications. A well-behaved Observable will call an Observer's onCompleted or onError methods exactly once.

Abstract Value Members

  1. abstract def complete(): Unit

    Notifies the Observer that the rxscalajs.Observable has finished sending push-based notifications.

    Notifies the Observer that the rxscalajs.Observable has finished sending push-based notifications.

    The rxscalajs.Observable will not call this method if it calls error.

  2. abstract def error(err: Any): Unit

    Notifies the Observer that the rxscalajs.Observable has experienced an error condition.

    Notifies the Observer that the rxscalajs.Observable has experienced an error condition.

    If the rxscalajs.Observable calls this method, it will not thereafter call next or completed.

  3. abstract def next(t: T): Unit

    Provides the Observer with new data.

    Provides the Observer with new data.

    The rxscalajs.Observable calls this closure 0 or more times.

    The rxscalajs.Observable will not call this method again after it calls either completed or error.
