121 * $Log$
122 * Revision 1.10 2006/05/05 14:25:05 strk
123 * moved getSegmentOctant out of .inl into .cpp, renamed private eiList to nodeList as in JTS, added more assertion checking and fixed doxygen comments
124 *
125 * Revision 1.9 2006/05/05 10:19:06 strk
126 * droppped SegmentString::getContext(), new name is getData() to reflect change in JTS
127 *

129 * * source/noding/ScaledNoder.cpp: removed use of SegmentString::setCoordinates().
130 * * source/headers/geos/noding/SegmentStrign.{h,inl}: removed new setCoordinates() interface.
131 *
132 * Revision 1.7 2006/05/04 07:43:44 strk
133 * output operator for SegmentString class
134 *
135 * Revision 1.6 2006/05/03 18:04:49 strk
136 * added SegmentString::setCoordinates() interface
137 *
