java.lang.Object
org.h2gis.api.AbstractFunction
org.h2gis.api.DeterministicScalarFunction
org.h2gis.functions.spatial.predicates.ST_Relate
All Implemented Interfaces:
org.h2gis.api.Function, org.h2gis.api.ScalarFunction
public class ST_Relate extends org.h2gis.api.DeterministicScalarFunction
This function is used to compute the relation between two geometries, as described in the SFS specification. It can be used in two ways. First, if it is given two geometries,it returns a 9-character String representation of the 2 geometries IntersectionMatrix. If it is given two geometries and a IntersectionMatrix representation, it will return a boolean : true it the two geometries' IntersectionMatrix match the given one, false otherwise.
