This should close bugs #86 and #89 * * Revision 1.30 2006/03/09 16:46:47 strk * geos::geom namespace definition, first pass at headers split * * Revision 1.29 2006/03/06 19:40:46 strk * geos::util namespace. New GeometryCollection::iterator interface, many cleanups. * * Revision 1.28 2006/03/03 10:46:21 strk * Removed 'using namespace' from headers, added missing headers in .cpp files, removed useless includes in headers (bug#46) * * Revision 1.27 2006/02/09 15:52:47 strk * GEOSException derived from std::exception; always thrown and cought by const ref. * * Revision 1.26 2006/01/31 19:07:33 strk * - Renamed DefaultCoordinateSequence to CoordinateArraySequence. * - Moved GetNumGeometries() and GetGeometryN() interfaces * from GeometryCollection to Geometry class. * - Added getAt(int pos, Coordinate &to) funtion to CoordinateSequence class. * - Reworked automake scripts to produce a static lib for each subdir and * then link all subsystem's libs togheter * - Moved C-API in it's own top-level dir capi/ * - Moved source/bigtest and source/test to tests/bigtest and test/xmltester * - Fixed PointLocator handling of LinearRings * - Changed CoordinateArrayFilter to reduce memory copies * - Changed UniqueCoordinateArrayFilter to reduce memory copies * - Added CGAlgorithms::isPointInRing() version working with * Coordinate::ConstVect type (faster!) * - Ported JTS-1.7 version of ConvexHull with big attention to * memory usage optimizations. * - Improved XMLTester output and user interface * - geos::geom::util namespace used for geom/util stuff * - Improved memory use in geos::geom::util::PolygonExtractor * - New ShortCircuitedGeometryVisitor class * - New operation/predicate package * * Revision 1.25 2005/06/23 14:22:33 strk * Inlined and added missing ::clone() for Geometry subclasses * * Revision 1.24 2004/12/16 16:27:24 strk * Fixed LinearRing::clone() to return LinearRing instead of LineString * * Revision 1.23 2004/12/03 22:52:56 strk * enforced const return of CoordinateSequence::toVector() method to derivate classes. * * Revision 1.22 2004/07/08 19:34:49 strk * Mirrored JTS interface of CoordinateSequence, factory and * default implementations. * Added CoordinateArraySequenceFactory::instance() function. * * Revision 1.21 2004/07/06 17:58:22 strk * Removed deprecated Geometry constructors based on PrecisionModel and * SRID specification. Removed SimpleGeometryPrecisionReducer capability * of changing Geometry's factory. Reverted Geometry::factory member * to be a reference to external factory. * * Revision 1.20 2004/07/05 10:50:20 strk * deep-dopy construction taken out of Geometry and implemented only * in GeometryFactory. * Deep-copy geometry construction takes care of cleaning up copies * on exception. * Implemented clone() method for CoordinateSequence * Changed createMultiPoint(CoordinateSequence) signature to reflect * copy semantic (by-ref instead of by-pointer). * Cleaned up documentation. * * Revision 1.19 2004/07/02 13:28:26 strk * Fixed all #include lines to reflect headers layout change. * Added client application build tips in README. * * Revision 1.18 2004/07/01 14:12:44 strk * * Geometry constructors come now in two flavors: * - deep-copy args (pass-by-reference) * - take-ownership of args (pass-by-pointer) * Same functionality is available through GeometryFactory, * including buildGeometry(). * * Revision 1.17 2004/06/28 21:11:43 strk * Moved getGeometryTypeId() definitions from geom.h to each geometry module. * Added holes argument check in Polygon.cpp. * * Revision 1.16 2004/04/20 13:24:15 strk * More leaks removed. * * Revision 1.15 2004/04/20 08:52:01 strk * GeometryFactory and Geometry const correctness. * Memory leaks removed from SimpleGeometryPrecisionReducer * and GeometryFactory. * * Revision 1.14 2004/04/01 10:44:33 ybychkov * All "geom" classes from JTS 1.3 upgraded to JTS 1.4 * * Revision 1.13 2003/11/07 01:23:42 pramsey * Add standard CVS headers licence notices and copyrights to all cpp and h * files. * * Revision 1.12 2003/10/11 03:23:22 strk * fixed spurious typos * **********************************************************************/
