Coordinate is the lightweight class used to store coordinates.
Definition Coordinate.h:60
Definition LineString.h:68
A planar graph of edges that is analyzed to sew the edges together.
Definition LineMergeGraph.h:59
void addEdge(const geom::LineString *lineString)
Adds an Edge, DirectedEdges, and Nodes for the given LineString representation of an edge.
A node in a PlanarGraph is a location where 0 or more Edge meet.
Definition planargraph/Node.h:45
Represents a directed graph which is embeddable in a planar surface.
Definition planargraph/PlanarGraph.h:60
Basic namespace for all GEOS functionalities.
