Method Detail

dist

public double dist(double[] center,
                   double[] min,
                   double[] max)

Specified by:

dist in interface RectangleDistanceFunction

dist

public double dist(double[] center,
                   RectangleEntry<?> entry)

Description copied from interface: RectangleDistanceFunction

Some algorithm use this method on the entries containing user supplied values. This can be overridden if the min/max coordinates only represent the bounding-box of the object. If your entry is actually a sphere, a car, an human or a cat, you may need this.

Specified by:

dist in interface RectangleDistanceFunction

Parameters:

center - a point

entry - a rectangle

Returns:

distance between point and rectangle
