                                                         int dimension1,
                                                         int dimension2)
                                                  throws SQLException

Given a (multi)geometry, returns a (multi)geometry consisting only of elements of the specified type. Sub-geometries that are not the specified type are ignored. If there are no sub-geometries of the right type, an EMPTY geometry will be returned. Only points, lines and polygons are extracted.

Parameters:

geometry -

dimension1 - one dimension to filter

dimension2 - second dimension to filter

Returns:

Throws:

SQLException
