Method Detail

execute

public static com.vividsolutions.jts.geom.Geometry execute(com.vividsolutions.jts.geom.Geometry geometry,
                                                           int pointIndex)
                                                    throws java.sql.SQLException

Parameters:

geometry - Geometry instance

pointIndex - Point index [1-NbPoints]

Returns:

Returns the nth point of a LINESTRING or a MULTILINESTRING containing exactly one LINESTRING; NULL otherwise. As the OGC specifies, ST_PointN is 1-N based.

Throws:

java.sql.SQLException - if index is out of bound.
