boolean	isDisposed()	Returns true if this resource has been disposed.
void	onError(Throwable e)	Notifies the SingleObserver that the Single has experienced an error condition.
void	onSubscribe(Disposable d)	Provides the SingleObserver with the means of cancelling (disposing) the connection (channel) with the Single in both synchronous (from within onSubscribe(Disposable) itself) and asynchronous manner.
void	onSuccess(T value)	Notifies the SingleObserver with a single item and that the Single has finished sending push-based notifications.

Method Details

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: SingleObserver

Provides the SingleObserver with the means of cancelling (disposing) the connection (channel) with the Single in both synchronous (from within onSubscribe(Disposable) itself) and asynchronous manner.

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 value)

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(Throwable).

Specified by:

onSuccess in interface SingleObserver<T>

Parameters:

value - the item emitted by the Single

onError

public void onError(Throwable e)

Description copied from interface: SingleObserver

Notifies the SingleObserver that the Single has experienced an error condition.

If the Single calls this method, it will not thereafter call SingleObserver.onSuccess(T).

Specified by:

onError in interface SingleObserver<T>

Parameters:

e - the exception encountered by the Single

disposeResource

void disposeResource()
