All Implemented Interfaces:

Function, ScalarFunction

public class ST_StartPoint
extends 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.
