Method Summary

Modifier and Type	Method	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(Throwable t)	Notifies the Observer that the Observable has experienced an error condition.
void	onNext(R t)	Provides the Observer with a new item to observe.
void	onSubscribe(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.
void	onSuccess(T t)	Notifies the SingleObserver with a single item and that the Single has finished sending push-based notifications.

Method Details

onNext

public void onNext(R 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(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>

Specified by:

onError in interface SingleObserver<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>

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

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>

Specified by:

onSubscribe in interface SingleObserver<T>

Parameters:

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

onSuccess

public void onSuccess(T t)

Description copied from interface: SingleObserver

Notifies the SingleObserver with a single item and that the Single has finished sending push-based notifications.

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

Specified by:

onSuccess in interface SingleObserver<T>

Parameters:

t - the item emitted by the Single
