Pure declaration header, find template implementation in Graph.h.
Declaration of class GraphAttributes which extends a Graph by additional attributes.
Declaration of classes GenericPoint, GenericPolyline, GenericLine, GenericSegment,...
Stores additional attributes of a graph (like layout information).
Class for the representation of nodes.
Definition Graph_d.h:177
Interface for computing a good / optimal vertex position.
virtual DPoint call(GraphAttributes &GA, node v)=0
computes a good position for the vertex v with respect to GA
void setBoundingBox(double x_min, double y_min, double x_max, double y_max)
Vertex has to be moved within the given bound.
DPoint operator()(GraphAttributes &GA, node v)
computes a good position for the vertex v with respect to GA
#define OGDF_EXPORT
Specifies that a function or class is exported by the OGDF DLL.
