* $Log$
* Revision 1.10 2006/05/05 14:25:05 strk
* moved getSegmentOctant out of .inl into .cpp, renamed private eiList to nodeList as in JTS, added more assertion checking and fixed doxygen comments
*
* Revision 1.9 2006/05/05 10:19:06 strk
* droppped SegmentString::getContext(), new name is getData() to reflect change in JTS
*
* Revision 1.8 2006/05/04 08:29:07 strk
* * source/noding/ScaledNoder.cpp: removed use of SegmentString::setCoordinates().
* * source/headers/geos/noding/SegmentStrign.{h,inl}: removed new setCoordinates() interface.
*
* Revision 1.7 2006/05/04 07:43:44 strk
* output operator for SegmentString class
*
* Revision 1.6 2006/05/03 18:04:49 strk
* added SegmentString::setCoordinates() interface
*
* Revision 1.5 2006/05/03 16:19:39 strk
* fit in 80 columns
*
* Revision 1.4 2006/05/03 15:26:02 strk
* testInvariant made public and always inlined
*
* Revision 1.3 2006/03/24 09:52:41 strk
* USE_INLINE => GEOS_INLINE
*
* Revision 1.2 2006/03/13 21:14:24 strk
* Added missing forward declarations
*
* Revision 1.1 2006/03/09 16:46:49 strk
* geos::geom namespace definition, first pass at headers split
