public interface GeomI

An interface used by all algorithms to abstractly geometric objects.

Method Summary
CoordinateSystemI	coordinateSystem()           Returns the coordinate system used by the polygon
PointI	getCentroid()           Returns a PointI describing the centroid of the object
double	getDistanceProxyTo(PointI point)           Returns an easily computable proxy that can be used to compare the distance to a point.
double	getDistanceTo(PointI point)           Returns the distance to a point.
PointI	getNearestPointTo(PointI point)           Returns a PointI describing the point on the boundary closest to 'point'.
RangeI	getRange()           Returns a RangeI describing the extent of the object.
