void countSegment(const geom::Coordinate &p1, const geom::Coordinate &p2)
Counts a segment.
static geom::Location locatePointInRing(const geom::Coordinate &p, const geom::CoordinateSequence &ring)
Determines the Location of a point in a ring. This method is an exemplar of how to use this class.
static int orientationIndex(const geom::Coordinate &p1, const geom::Coordinate &p2, const geom::Coordinate &q)
Returns the index of the direction of the point q relative to a vector specified by p1-p2.
The internal representation of a list of coordinates inside a Geometry.
