  • Method Details

    • requestFusion

      public int requestFusion(int mode)
      Description copied from interface: QueueFuseable
      Request a fusion mode from the upstream.

      This should be called before onSubscribe returns.

      Calling this method multiple times or after onSubscribe finished is not allowed and may result in undefined behavior.

      Parameters:
      mode - the requested fusion mode, allowed values are QueueFuseable.SYNC, QueueFuseable.ASYNC, QueueFuseable.ANY combined with QueueFuseable.BOUNDARY (e.g., requestFusion(SYNC | BOUNDARY)).
      Returns:
      the established fusion mode: QueueFuseable.NONE, QueueFuseable.SYNC, QueueFuseable.ASYNC.

    • poll

      @Nullable public T poll()
      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.

      Returns:
      the item or null to indicate an empty queue

    • 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).

      Returns:
      true if the queue is empty

    • clear

      public void clear()
      Description copied from interface: SimpleQueue
      Removes all enqueued items from this queue.

    • dispose

      public void dispose()
      Description copied from interface: Disposable
      Dispose the resource, the operation should be idempotent.

    • isDisposed

      public boolean isDisposed()
      Description copied from interface: Disposable
      Returns true if this resource has been disposed.
      Returns:
      true if this resource has been disposed

    • run

      void run()
