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
Basic namespace for all GEOS functionalities.
Definition: IndexedNestedRingTester.h:25
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.
