SegmentNode* geos::noding::SegmentNodeList::add ( const geom::Coordinate intPt,
std::size_t  segmentIndex 

Adds an intersection into the list, if it isn't already there. The input segmentIndex is expected to be normalized.

the SegmentIntersection found or added. It will be destroyed at SegmentNodeList destruction time.
intPtthe intersection Coordinate, will be copied
void geos::noding::SegmentNodeList::addEndpoints ( )

Adds entries for the first and last points of the edge to the list

void geos::noding::SegmentNodeList::addSplitEdges ( std::vector< SegmentString * > &  edgeList)

Creates new edges for all the edges that the intersections in this list split the parent edge into. Adds the edges to the input list (this is so a single list can be used to accumulate all split edges for a Geometry).
