          org.h2gis.h2spatialext.function.spatial.distance.ST_ClosestPoint

All Implemented Interfaces:

Function, ScalarFunction

public class ST_ClosestPoint
extends DeterministicScalarFunction

ST_ClosestPoint returns the 2D point on geometry A that is closest to geometry B. If the closest point is not unique, it returns the first one it finds. This means that the point returned depends on the order of the geometry's coordinates.
