Method Detail

subscribeActual

protected void subscribeActual(SingleObserver<? super T> observer)

Description copied from class: Single

Implement this method in subclasses to handle the incoming SingleObservers.

There is no need to call any of the plugin hooks on the current Single instance or the SingleObserver; all hooks and basic safeguards have been applied by Single.subscribe(SingleObserver) before this method gets called.

Specified by:

subscribeActual in class Single<T>

Parameters:

observer - the SingleObserver to handle, not null

add

boolean add(SingleCache.CacheDisposable<T> observer)

remove

void remove(SingleCache.CacheDisposable<T> observer)

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(java.lang.Throwable).

Specified by:

onSuccess in interface SingleObserver<T>

Parameters:

value - the item emitted by the Single

onError

public void onError(java.lang.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
