      • poll

        @Nullable
        public final @Nullable java.lang.Integer 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 final 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 final void clear()
        Description copied from interface: SimpleQueue
        Removes all enqueued items from this queue.
