Constructor.

CompoundScoreComparator

public CompoundScoreComparator(IScoreComparator[] comparators)

Constructor with array of comparators.

Parameters:

comparators - array of comparators

Method Detail

compare

public int compare(IScore score0,
                   IScore score1)

Compares two compound scores. This method returns 0 if the comparison has a indifferent result. It returns -2 resp. -1 if score0 strongly resp. weakly dominates score1. It returns 2 resp. 1 if score0 is strongly resp. weakly dominated by score1.

Specified by:

compare in interface IScoreComparator

Specified by:

compare in class AbstractScoreComparator

Parameters:

score0 - first compound score

score1 - second compound score

Returns:

result of comparison
