Class ST_StartPoint

java.lang.Object

org.h2gis.api.AbstractFunction

org.h2gis.api.DeterministicScalarFunction

org.h2gis.functions.spatial.properties.ST_StartPoint

All Implemented Interfaces:

org.h2gis.api.Function, org.h2gis.api.ScalarFunction

public class ST_StartPoint
extends org.h2gis.api.DeterministicScalarFunction

Returns the first coordinate of a Geometry as a POINT, given that the Geometry is a LINESTRING or a MULTILINESTRING containing only one LINESTRING; Returns NULL for all other Geometries.
