 SegmentNode (const NodedSegmentString &ss, const geom::Coordinate &nCoord, size_t nSegmentIndex, int nSegmentOctant)
bool isInterior () const
 Return true if this Node is internal (not on the boundary) of the corresponding segment. Currently only the first segment endpoint is checked, actually.
bool isEndPoint (unsigned int maxSegmentIndex) const
int compareTo (const SegmentNode &other)

Public Attributes

geom::Coordinate coord
 the point of intersection (own copy)
