    Method
    Description
    void
    addListener(UpdateListener<T> listener)
    The add-method for listeners for a dynamic preference aggregator
    PreferenceOrder<T>
    aggregate(List<PreferenceOrder<T>> input)
    Abstract class for implementation of dynamic preference aggregation
    void
    removeListener(UpdateListener<T> listener)
    The remove-method for listeners for a dynamic preference aggregator
    PreferenceOrder<T>
    update(Update<T> update, List<PreferenceOrder<T>> input)
    This update stream is going to be used for dynamic changes in a preferences orders Input: ArrayList(Quadruple(PreferenceOrder, Number of Operations, Operation, Element)) e.g: weakening element b in PO test 2 times needs quadruple like this: Quadruple(test, 2, WEAKEN, b) Possible Structures: ArrayList, Queue Empty initialization, update() if stream is not empty
