public DynamicScoringPreferenceAggregator(WeightVector v)

Constructor with given weight vector

Parameters:

v - the weight vector

Method Details

aggregate

public PreferenceOrder<T> aggregate(List<PreferenceOrder<T>> input)

This method aggregates the given preference orders according to the WeightVector used within construction

Specified by:

aggregate in interface DynamicPreferenceAggregator<T>

Parameters:

input - the array of preference orders to be aggregated

Returns:

the final result as a preference order

update

public PreferenceOrder<T> update(Update<T> update,
 List<PreferenceOrder<T>> input)
                          throws IndexOutOfBoundsException,
NullPointerException

The update-method for dynamically changing the input for preference aggregation

Specified by:

update in interface DynamicPreferenceAggregator<T>

Parameters:

update - the update element containing the changes to be applied

input - some input

Returns:

a preference order

Throws:

IndexOutOfBoundsException

NullPointerException

update

public PreferenceOrder<T> update(UpdateStream<T> stream,
 List<PreferenceOrder<T>> input)

this method extends the update-functionality with input-streams consisting of Update-elements

Parameters:

stream - the input stream with the Update-elements

input - some input

Returns:

the newly aggregated preference order after all updates are applied

addListener

public void addListener(UpdateListener<T> listener)

adds a listener to this dynamic preference aggregator

Specified by:

addListener in interface DynamicPreferenceAggregator<T>

Parameters:

listener - an update listener

removeListener

public void removeListener(UpdateListener<T> listener)

removes a listener from this dynamic preference aggregator

Specified by:

removeListener in interface DynamicPreferenceAggregator<T>

Parameters:

listener - an update listener
