Coordinate is the lightweight class used to store coordinates.
Definition: Coordinate.h:58
Implementation of Dimensionally Extended Nine-Intersection Model (DE-9IM) matrix.
Definition: IntersectionMatrix.h:51
A EdgeEndStar is an ordered list of EdgeEnds around a node.
Definition: EdgeEndStar.h:62
The node component of a geometry graph.
Definition: geomgraph/Node.h:59
Represents a node in the topological graph used to compute spatial relationships.
Definition: RelateNode.h:45
void computeIM(geom::IntersectionMatrix &im) override
Basic nodes do not compute IMs.
void updateIMFromEdges(geom::IntersectionMatrix &im)
Basic namespace for all GEOS functionalities.
