Method Details

onNext

public void onNext(R t)

Specified by:

onNext in interface org.reactivestreams.Subscriber<T>

onError

public void onError(Throwable t)

Description copied from interface: MaybeObserver

Notifies the MaybeObserver that the Maybe has experienced an error condition.

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

Specified by:

onError in interface MaybeObserver<T>

Specified by:

onError in interface org.reactivestreams.Subscriber<T>

Parameters:

t - the exception encountered by the Maybe

onComplete

public void onComplete()

Description copied from interface: MaybeObserver

Called once the deferred computation completes normally.

Specified by:

onComplete in interface MaybeObserver<T>

Specified by:

onComplete in interface org.reactivestreams.Subscriber<T>

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

onSubscribe

public void onSubscribe(Disposable d)

Description copied from interface: MaybeObserver

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

Specified by:

onSubscribe in interface MaybeObserver<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: MaybeObserver

Notifies the MaybeObserver with one item and that the Maybe has finished sending push-based notifications.

The Maybe will not call this method if it calls MaybeObserver.onError(Throwable).

Specified by:

onSuccess in interface MaybeObserver<T>

Parameters:

t - the item emitted by the Maybe

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<T>

Specified by:

onSubscribe in interface org.reactivestreams.Subscriber<T>
