      boolean isEmpty()
      Returns true if the queue is empty.
      void onComplete()
      Notifies the Observer that the Observable has finished sending push-based notifications.
      void onError​(java.lang.Throwable t)
      Notifies the Observer that the Observable has experienced an error condition.
      void onNext​(T t)
      Provides the Observer with a new item to observe.
      void onSubscribe​(Disposable d)
      Provides the Observer with the means of cancelling (disposing) the connection (channel) with the Observable in both synchronous (from within Observer.onNext(Object)) and asynchronous manner.
      T poll()
      Tries to dequeue a value (non-null) or returns null if the queue is empty.
      int requestFusion​(int mode)
      Request a fusion mode from the upstream.

        Dispose the resource, the operation should be idempotent.

        Specified by:
        isDisposed in interface Disposable
        Returns:
        true if this resource has been disposed

        boolean checkTerminated​(boolean d,
                                boolean empty,
                                Observer<? super T> a)
      • 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.
      • 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
