                                                      com.vividsolutions.jts.geom.Geometry splitter)

returns the JTS Multipolygon geometry corresponding to the cutting of the first polygon contained into the geometries Vector with the second object that must be a linestring.

a result will be returned iff it is composed of polygons and multipolygons

Parameters:

sourceGeom - DOCUMENT ME!

splitter - DOCUMENT ME!

Returns:

A MultiPolygon resulting from the spatial analysis operation, or null if geometries vector does not contain 2 polygons, or if cutting operations produced something else than polygons or multipolygons
