addPoint

public static com.vividsolutions.jts.geom.Geometry addPoint(com.vividsolutions.jts.geom.Geometry geometry,
                                                            com.vividsolutions.jts.geom.Point point)
                                                     throws SQLException

Returns a new geometry based on an existing one, with a specific point as a new vertex. A default distance 10E-6 is used to snap the input point.

Parameters:

geometry -

point -

Returns:

Throws:

SQLException

addPoint

public static com.vividsolutions.jts.geom.Geometry addPoint(com.vividsolutions.jts.geom.Geometry geometry,
                                                            com.vividsolutions.jts.geom.Point point,

Returns a new geometry based on an existing one, with a specific point as a new vertex.

Parameters:

geometry -

point -

tolerance -

Returns:

Null if the vertex cannot be inserted

Throws:

SQLException - If the vertex can be inserted but it makes the geometry to be in an invalid shape
