Method Details

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 CompletableObserver

Specified by:

onSubscribe in interface MaybeObserver<T>

Specified by:

onSubscribe in interface SingleObserver<T>

Parameters:

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

onComplete

public void onComplete()

Description copied from interface: MaybeObserver

Called once the deferred computation completes normally.

Specified by:

onComplete in interface CompletableObserver

Specified by:

onComplete in interface MaybeObserver<T>

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(Throwable).

Specified by:

onSuccess in interface MaybeObserver<T>

Specified by:

onSuccess in interface SingleObserver<T>

Parameters:

t - 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 CompletableObserver

Specified by:

onError in interface MaybeObserver<T>

Specified by:

onError in interface SingleObserver<T>

Parameters:

e - the exception encountered by the Single

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

dispose

public void dispose()

Description copied from interface: Disposable

Dispose the resource, the operation should be idempotent.

Specified by:

dispose in interface Disposable
