public abstract class FeatureDeriveFromPair
extends FeaturePairObjects

Base class for evaluating FeaturePairObjects in terms of another feature that operates on elements (first, second, merged etc.).

This class provides methods to calculate feature values for the first, second, and merged objects in a pair, using a specified feature for single objects.
