  • SafeObserver

    public SafeObserver(@NonNullObserver<? superT> downstream)

    Constructs a SafeObserver by wrapping the given actual Observer.

    Parameters:

    downstream - the actual Observer to wrap, not null (not validated)

• Method Detail

  • onSubscribe

    public void onSubscribe(@NonNullDisposable d)

    Description copied from interface: Observer
    Provides the Observer with the means of cancelling (disposing) the connection (channel) with the Observable in both synchronous (from withinObserver.onNext(Object)) and asynchronous manner.

    Specified by:

    onSubscribe in interface Observer<T>

    Parameters:

    d - the Disposable instance whoseDisposable.dispose() can be called anytime to cancel the connection

  • dispose

    public void dispose()

    Description copied from interface: Disposable
    Dispose the resource, the operation should be idempotent.

    Specified by:

    dispose in interface Disposable

  • isDisposed

    public boolean isDisposed()

    Description copied from interface: Disposable
    Returns true if this resource has been disposed.

    Specified by:

    isDisposed in interface Disposable

    Returns:

    true if this resource has been disposed

  • onNext

    public void onNext(@NonNullT t)

    Description copied from interface: Observer
    Provides the Observer with a new item to observe.

    TheObservable may call this method 0 or more times.

    TheObservable will not call this method again after it calls eitherObserver.onComplete() orObserver.onError(java.lang.Throwable).

    Specified by:

    onNext in interface Observer<T>

    Parameters:

    t - the item emitted by the Observable

  • onError

    public void onError(@NonNullThrowable t)

    Description copied from interface: Observer
    Notifies the Observer that theObservable has experienced an error condition.

    If theObservable calls this method, it will not thereafter callObserver.onNext(T) orObserver.onComplete().

    Specified by:

    onError in interface Observer<T>

    Parameters:

    t - the exception encountered by the Observable

  • onComplete

    public void onComplete()

    Description copied from interface: Observer
    Notifies the Observer that theObservable has finished sending push-based notifications.

    TheObservable will not call this method if it callsObserver.onError(java.lang.Throwable).

    Specified by:

    onComplete in interface Observer<T>
