      • 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>

      • onNext

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

      • onError

        public void onError​(java.lang.Throwable t)
        Specified by:
        onError in interface org.reactivestreams.Subscriber<T>

      • onComplete

        public void onComplete()
        Specified by:
        onComplete in interface org.reactivestreams.Subscriber<T>

      • cancel

        public void cancel()
        Specified by:
        cancel in interface org.reactivestreams.Subscription

      • request

        public void request​(long n)
        Specified by:
        request in interface org.reactivestreams.Subscription

      • clear

        public void clear()
        Description copied from interface: SimpleQueue
        Removes all enqueued items from this queue.
        Specified by:
        clear in interface SimpleQueue<T>

      • isEmpty

        public boolean isEmpty()
        Description copied from interface: SimpleQueue
        Returns true if the queue is empty.

        Note however that due to potential fused functions in SimpleQueue.poll() it is possible this method returns false but then poll() returns null because the fused function swallowed the available item(s).

        Specified by:
        isEmpty in interface SimpleQueue<T>
        Returns:
        true if the queue is empty

      • poll

        @Nullable
public T poll()
       throws java.lang.Throwable
        Description copied from interface: SimpleQueue
        Tries to dequeue a value (non-null) or returns null if the queue is empty.

        If the producer uses SimpleQueue.offer(Object, Object) and when polling in pairs, if the first poll() returns a non-null item, the second poll() is guaranteed to return a non-null item as well.

        Specified by:
        poll in interface SimpleQueue<T>
        Returns:
        the item or null to indicate an empty queue
        Throws:
        java.lang.Throwable - if some pre-processing of the dequeued item (usually through fused functions) throws.
