 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

Parameters:

update - an update

input - some input

Returns:

a preference order

addListener

The add-method for listeners for a dynamic preference aggregator

Parameters:

listener - an update listener

removeListener

void removeListener(UpdateListener<T> listener)

The remove-method for listeners for a dynamic preference aggregator

Parameters:

listener - an update listener
