00210  * $Log$
00211  * Revision 1.8  2006/06/12 10:10:39  strk
00212  * Fixed getGeometryN() to take size_t rather then int, changed unsigned int parameters to size_t.
00213  *
00214  * Revision 1.7  2006/05/04 15:49:39  strk
00215  * updated all Geometry::getDimension() methods to return Dimension::DimensionType (closes bug#93)
00216  *
00217  * Revision 1.6  2006/04/28 10:55:39  strk
00218  * Geometry constructors made protected, to ensure all constructions use GeometryFactory,
00219  * which has been made friend of all Geometry derivates. getNumPoints() changed to return
00220  * size_t.
00221  *
00222  * Revision 1.5  2006/04/10 18:15:09  strk
00223  * Changed Geometry::envelope member to be of type auto_ptr<Envelope>.
00224  * Changed computeEnvelopeInternal() signater to return auto_ptr<Envelope>
00225  *
00226  * Revision 1.4  2006/04/07 09:54:30  strk
00227  * Geometry::getNumGeometries() changed to return 'unsigned int'
00228  * rather then 'int'
00229  *
00230  * Revision 1.3  2006/03/24 09:52:41  strk
00231  * USE_INLINE => GEOS_INLINE
00232  *
00233  * Revision 1.2  2006/03/23 12:12:01  strk
00234  * Fixes to allow build with -DGEOS_INLINE
00235  *
00236  * Revision 1.1  2006/03/09 16:46:49  strk
00237  * geos::geom namespace definition, first pass at headers split
