I'm not sure why strk is making this comment. JTS/GEOS supports empty geometries of all types (as per the OGC SFS).
That said, what kind of empty geometry is returned from various methods is open to interpretation, I think. In some cases I think the best you can do is to return an empty GC. In other cases a more precise kind of empty geometry can be returned (and as I noted, JTS/GEOS could probably improve it's semantics in a few cases. ) Martin Davis, Senior Technical Architect Vivid Solutions Inc. www.vividsolutions.com Suite #1A-2328 Government Street Victoria, B.C.
