    00193  * $Log$
    00194  * Revision 1.8  2006/06/12 10:10:39  strk
    00195  * Fixed getGeometryN() to take size_t rather then int, changed unsigned int parameters to size_t.
    00196  *
    00197  * Revision 1.7  2006/05/04 15:49:39  strk
    00198  * updated all Geometry::getDimension() methods to return Dimension::DimensionType (closes bug#93)
    00199  *
    00200  * Revision 1.6  2006/04/28 10:55:39  strk
    00201  * Geometry constructors made protected, to ensure all constructions use GeometryFactory,
    00202  * which has been made friend of all Geometry derivates. getNumPoints() changed to return
    00203  * size_t.
    00204  *
    00205  * Revision 1.5  2006/04/10 18:15:09  strk
    00206  * Changed Geometry::envelope member to be of type auto_ptr<Envelope>.
    00207  * Changed computeEnvelopeInternal() signater to return auto_ptr<Envelope>
    00208  *
    00209  * Revision 1.4  2006/04/07 09:54:30  strk
    00210  * Geometry::getNumGeometries() changed to return 'unsigned int'
    00211  * rather then 'int'
    00212  *
    00213  * Revision 1.3  2006/03/24 09:52:41  strk
    00214  * USE_INLINE => GEOS_INLINE
    00215  *
    00216  * Revision 1.2  2006/03/23 12:12:01  strk
    00217  * Fixes to allow build with -DGEOS_INLINE
    00218  *
    00219  * Revision 1.1  2006/03/09 16:46:49  strk
    00220  * geos::geom namespace definition, first pass at headers split
    00221  *
