Public Member Functions

 Repulsion (GraphAttributes &AG)
 
- Public Member Functions inherited from ogdf::davidson_harel::NodePairEnergy
 NodePairEnergy (const string energyname, GraphAttributes &AG)
 
virtual ~NodePairEnergy ()
 
void computeEnergy () override
 computes energy for the layout at the beginning of the optimization process
 
- Public Member Functions inherited from ogdf::davidson_harel::EnergyFunction
 EnergyFunction (const string &funcname, GraphAttributes &AG)
 Initializes data dtructures to speed up later computations.
 
virtual ~EnergyFunction ()
 
void candidateTaken ()
 Changes m_currentX and m_currentY by setting the position of m_testNode to m_testX and m_testY. Sets m_energy to m_candidateEnergy. Computes the energy of the layout stored in AG.
 
double computeCandidateEnergy (const node v, const DPoint &newPos)
 sets m_testNode, m_testX and m_testY and computes the energy for the new configuration (vertex v moves to newPos)
 
double energy () const
 
string getName () const
 prints the name of the energy function
 

Private Member Functions

double computeCoordEnergy (node, node, const DPoint &, const DPoint &) const override
 Computes the energy stored by a pair of vertices at the given positions.
 

Additional Inherited Members

- Protected Member Functions inherited from ogdf::davidson_harel::NodePairEnergy
bool adjacent (const node v, const node w) const
 returns true in constant time if two vertices are adjacent.
 
int nodeNum (node v) const
 Returns the internal number given to each vertex.
 
const DIntersectableRectshape (const node v) const
 Returns the shape of a vertex v as a DIntersectableRect.
 
- Protected Member Functions inherited from ogdf::davidson_harel::EnergyFunction
DPoint currentPos (const node v) const
 returns the current position of vertex v
 
node testNode () const
 returns the vertex that is under consideration in the current step
 
DPoint testPos ()
 returns candidate position for the node to be moved
 
- Protected Attributes inherited from ogdf::davidson_harel::EnergyFunction
double m_candidateEnergy
 the energy of the layout if the candidate layout is chosen
 
double m_energy
 energy of the current layout
 
const Graphm_G
 the graph that should be drawn
 
const string m_name
 name of the energy function
