All Implemented Interfaces:

Function, ScalarFunction

public class ST_ClosestCoordinate
extends DeterministicScalarFunction

ST_ClosestCoordinate computes the closest coordinate(s) contained in the given geometry starting from the given point, using the 2D distance. If the coordinate is unique, it is returned as a POINT. If it is not, then all closest coordinates are returned in a MULTIPOINT.
