Coordinate is the lightweight class used to store coordinates.
Definition Coordinate.h:60
Implementation of Dimensionally Extended Nine-Intersection Model (DE-9IM) matrix.
Definition IntersectionMatrix.h:54
A EdgeEndStar is an ordered list of EdgeEnds around a node.
Definition EdgeEndStar.h:65
The node component of a geometry graph.
Definition geomgraph/Node.h:62
Represents a node in the topological graph used to compute spatial relationships.
Definition RelateNode.h:46
void computeIM(geom::IntersectionMatrix &im) override
Basic nodes do not compute IMs.
void updateIMFromEdges(geom::IntersectionMatrix &im)
Basic namespace for all GEOS functionalities.
