      All Methods Instance Methods Concrete Methods 
      Modifier and Type Method Description
      void cancel()  
      void onComplete()
      Called once the deferred computation completes normally.
      void onError​(java.lang.Throwable t)
      Notifies the MaybeObserver that the Maybe has experienced an error condition.
      void onNext​(R t)  
      void onSubscribe​(Disposable d)
      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.
      void onSubscribe​(org.reactivestreams.Subscription s)
      Implementors of this method should make sure everything that needs to be visible in Subscriber.onNext(Object) is established before calling Subscription.request(long).
      void onSuccess​(T t)
      Notifies the MaybeObserver with one item and that the Maybe has finished sending push-based notifications.
      void request​(long n)

    • Method Detail

      • onNext

        public void onNext​(R t)
        Specified by:
        onNext in interface org.reactivestreams.Subscriber<T>

      • onError

        public void onError​(java.lang.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​(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>
