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.
