Method Details

onSubscribe

public void onSubscribe(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

onNext

public void onNext(T value)

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(Throwable).

Specified by:

onNext in interface Observer<T>

Parameters:

value - the item emitted by the Observable

onError

public void onError(Throwable e)

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:

e - 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(Throwable).

Specified by:

onComplete in interface Observer<T>

dispose

public void dispose()

Description copied from interface: Disposable

Dispose the resource, the operation should be idempotent.

Specified by:

dispose in interface Disposable

drainAndDispose

void drainAndDispose()

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

disposeAll

void disposeAll()

innerNext

public void innerNext(InnerQueuedObserver<R> inner,
 R value)

Specified by:

innerNext in interface InnerQueuedObserverSupport<T>

innerError

public void innerError(InnerQueuedObserver<R> inner,
 Throwable e)

Specified by:

innerError in interface InnerQueuedObserverSupport<T>

innerComplete

public void innerComplete(InnerQueuedObserver<R> inner)

Specified by:

innerComplete in interface InnerQueuedObserverSupport<T>

drain

public void drain()

Specified by:

drain in interface InnerQueuedObserverSupport<T>
