Class DistanceFunction.RectangleDist

java.lang.Object

org.tinspin.index.rtree.DistanceFunction.RectangleDist

All Implemented Interfaces:

DistanceFunction

Enclosing interface:

DistanceFunction

public static class DistanceFunction.RectangleDist
extends Object
implements DistanceFunction

This class calculates the distance to a rectangular shaped object. This class completely ignores the center given as parameter to the interface. TODO: maybe we could get rid of the center parameter altogether and always let the DistanceFunction hold it's reference points?
