Interface AbstractObjectMetric<T>

Type Parameters:

T - the underlying type of the metric

All Known Subinterfaces:

AbstractObjectMetricSpace<T>, AbstractSearchableMetricSpace<T>

All Known Implementing Classes:

EuclideanMetricSpace, ExplicitLandmarkSelector, ExplicitMetricSpace, GeometricSimplexStream, KDEuclideanMetricSpace, LandmarkSelector, MaxMinLandmarkSelector, ObjectSearchableFiniteMetricSpace, RandomLandmarkSelector, SkeletalMetric

public interface AbstractObjectMetric<T>

This interface defines a metric on the type T. Note that an implementing class should obey the axioms of a metric space - namely symmetry, positivity and the triangle inequality.
