trait Observer[-T] extends AnyRef

Provides a mechanism for receiving push-based notifications.

After an Observer calls an rx.lang.scala.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.

    Notifies the Observer that the rx.lang.scala.Observable has finished sending push-based notifications.

    Notifies the Observer that the rx.lang.scala.Observable has finished sending push-based notifications.

    The rx.lang.scala.Observable will not call this method if it calls onError.

  16. def onError(error: Throwable): Unit

    Notifies the Observer that the rx.lang.scala.Observable has experienced an error condition.

    Notifies the Observer that the rx.lang.scala.Observable has experienced an error condition.

    If the rx.lang.scala.Observable calls this method, it will not thereafter call onNext or onCompleted.

  17. def onNext(value: T): Unit

    Provides the Observer with new data.

    Provides the Observer with new data.

    The rx.lang.scala.Observable calls this closure 0 or more times.

    The rx.lang.scala.Observable will not call this method again after it calls either onCompleted or onError.
