Package org.tinspin.index

Class RectangleDistanceFunction.RectangleDist

java.lang.Object

org.tinspin.index.RectangleDistanceFunction.RectangleDist

All Implemented Interfaces:

RectangleDistanceFunction

Enclosing interface:

RectangleDistanceFunction

public static class RectangleDistanceFunction.RectangleDist
extends Object
implements RectangleDistanceFunction

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 RectangleDistanceFunction hold it's reference points?
