Interface FoldableAction

  • All Superinterfaces:
    Action, ModelObject
    All Known Implementing Classes:

    public interface FoldableAction
    extends Action
    An action interface that allows action data to be folded together.

    Action can implement this optional marker interface to be notified when the Queue.Task that it's added to the queue with is determined to be "already in the queue".

    This is useful for passing on parameters to the task that's already in the queue.

        void foldIntoExisting​(Queue.Item item,
