  All Methods

  Modifier and Type	Method and Description
  void	dispose () Dispose the resource, the operation should be idempotent.
  boolean	isDisposed () Returns true if this resource has been disposed.
  void	onComplete () Notifies the Observer that the Observable has finished sending push-based notifications.
  void	onError (@NonNull Throwable t) Notifies the Observer that the Observable has experienced an error condition.
  void	onNext (T t) Provides the Observer with a new item to observe.
  void	onSubscribe (@NonNull Disposable d) Provides the Observer with the means of cancelling (disposing) the connection (channel) with the Observable in both synchronous (from within Observer.onNext(Object)) and asynchronous manner.

  • SafeObserver

    public SafeObserver(@NonNull
     @NonNull Observer<? super T> 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(@NonNull
     @NonNull Disposable 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 within Observer.onNext(Object)) and asynchronous manner.

    Specified by:

    onSubscribe in interface Observer<T>

    Parameters:

    d - the Disposable instance whose Disposable.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(@NonNull
     T t)

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

    The Observable may call this method 0 or more times.

    The Observable will not call this method again after it calls either Observer.onComplete() or Observer.onError(java.lang.Throwable).

    Specified by:

    onNext in interface Observer<T>

    Parameters:

    t - the item emitted by the Observable

  • onError

    public void onError(@NonNull
     @NonNull Throwable t)

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

    If the Observable calls this method, it will not thereafter call Observer.onNext(T) or Observer.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 the Observable has finished sending push-based notifications.

    The Observable will not call this method if it calls Observer.onError(java.lang.Throwable).

    Specified by:

    onComplete in interface Observer<T>
