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 SingleObserver<S>

Parameters:

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

onSuccess

public void onSuccess(S 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<S>

Parameters:

value - the item emitted by the Single

onSubscribe

public void onSubscribe(org.reactivestreams.Subscription s)

Description copied from interface: FlowableSubscriber

Implementors of this method should make sure everything that needs to be visible in Subscriber.onNext(Object) is established before calling Subscription.request(long). In practice this means no initialization should happen after the request() call and additional behavior is thread safe in respect to onNext.

Specified by:

onSubscribe in interface FlowableSubscriber<S>

Specified by:

onSubscribe in interface org.reactivestreams.Subscriber<S>

onNext

public void onNext(T t)

Specified by:

onNext in interface org.reactivestreams.Subscriber<S>

onComplete

public void onComplete()

Specified by:

onComplete in interface org.reactivestreams.Subscriber<S>

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<S>

Specified by:

onError in interface org.reactivestreams.Subscriber<S>

Parameters:

e - the exception encountered by the Single

request

public void request(long n)

Specified by:

request in interface org.reactivestreams.Subscription

cancel

public void cancel()

Specified by:

cancel in interface org.reactivestreams.Subscription
