    00326  *         * configure.in: incremented CAPI minor version, to avoid                        falling behind any future version from the 2.2. branch.
    00327  *         * source/geom/Geometry.cpp, source/geom/GeometryFactory.cpp,
    00328  *         source/geomgraph/EdgeRing.cpp,

    00332  *         source/headers/geos/geomgraph/EdgeRing.h:
    00333  *         updated doxygen comments (sync with JTS head).
    00334  *         * source/headers/geos/platform.h.in: include <inttypes.h>
    00335  *         rather then <stdint.h>
    00336  *
    00337  * Revision 1.10  2006/06/19 21:17:24  strk
    00338  * port info and doxygen dox.

    00340  * Revision 1.9  2006/04/28 11:56:52  strk
    00341  * * source/geom/GeometryFactory.cpp, source/headers/geos/geom/GeometryFactory.h: added LineString copy constructor.
    00342  * * source/geom/Polygon.cpp: fixed getBoundary method to always return a geometry composed by LineStrings (not LinearRings)
    00343  *
    00344  * Revision 1.8  2006/04/12 11:39:34  strk
    00345  * Removed Geometry.h and CoordinateSequence.h includes.
    00346  * The former created a circular dependency.
    00347  *
    00348  * Revision 1.7  2006/04/11 11:16:25  strk
    00349  * Added LineString and LinearRing constructors by auto_ptr

    00351  * Revision 1.6  2006/04/10 13:09:49  strk
    00352  * Added GeometryFactory::defaultInstance()
    00353  * Made Geometry::INTERNAL_GEOMETRY_FACTORY an alias for it
    00354  * removed last deletion from Unload::Release class
    00355  *
    00356  * Revision 1.5  2006/03/31 17:51:26  strk
    00357  * A few assertion checking, comments cleanup, use of initialization lists
    00358  * in constructors, handled NULL parameters.
    00359  *
    00360  * Revision 1.4  2006/03/28 16:33:14  strk
    00361  * Added note about args responsibility in GeometryFactory constructor
    00362  *
    00363  * Revision 1.3  2006/03/24 09:52:41  strk
    00364  * USE_INLINE => GEOS_INLINE
    00365  *
    00366  * Revision 1.2  2006/03/20 17:27:03  strk
    00367  * Bug #72 - Missing <vector> header
    00368  *
    00369  * Revision 1.1  2006/03/09 16:46:49  strk
