 * $Log$
 * Revision 1.16  2006/03/27 10:36:51  strk
 * added missing space in exception message
 *
 * Revision 1.15  2006/03/20 16:57:44  strk
 * spatialindex.h and opValid.h headers split
 *
 * Revision 1.14  2006/03/03 10:46:22  strk
 * Removed 'using namespace' from headers, added missing headers in .cpp files, removed useless includes in headers (bug#46)
 *
 * Revision 1.13  2006/03/01 10:48:55  strk
 * Changed static TopologyValidationError::errMsg[] from 'string' to 'const char*'
 * to reduce dynamic memory allocations.
 *
 * Revision 1.12  2006/02/23 23:17:52  strk
 * - Coordinate::nullCoordinate made private
 * - Simplified Coordinate inline definitions
 * - LMGeometryComponentFilter definition moved to LineMerger.cpp file
 * - Misc cleanups
 *
 * Revision 1.11  2006/02/19 19:46:50  strk
 * Packages <-> namespaces mapping for most GEOS internal code (uncomplete, but working). Dir-level libs for index/ subdirs.
 *
 * Revision 1.10  2006/01/20 19:11:09  strk
 * Updated last port info
 *
 * Revision 1.9  2005/11/04 11:04:09  strk
 * Ported revision 1.38 of IsValidOp.java (adding closed Ring checks).
 * Changed NestedRingTester classes to use Coorinate pointers
 * rather then actual objects, to speedup NULL tests.
 * Added JTS port revision when applicable.
 *
 * Revision 1.8  2004/11/05 11:41:57  strk
 * Made IsValidOp handle IllegalArgumentException throw from GeometryGraph
 * as a sign of invalidity (just for Polygon geometries).
 * Removed leaks generated by this specific exception.
 *
 * Revision 1.7  2004/09/13 10:14:47  strk
 * Added INVALID_COORDINATE code num and error message.
 *
 * Revision 1.6  2004/07/02 13:28:29  strk
 * Fixed all #include lines to reflect headers layout change.
 * Added client application build tips in README.
 *
 * Revision 1.5  2003/11/07 01:23:43  pramsey
 * Add standard CVS headers licence notices and copyrights to all cpp and h
 * files.
