               int width,
               int height)

Method Detail

advancePositions

public void advancePositions()

rescalePositions

public void rescalePositions(Set nodes,
                             int width,
                             int height,
                             int pad)

Rescales the x and y coordinates of each node so that the network will maximally fill the display. Will result in some distortion. Called internally if rescale is set to true, will rescale smoothly if animateTransitions is true.

Parameters:

nodes - the nodes to rescale.

rescalePositions

public void rescalePositions(Set nodes,
                             double xpercent,
                             int pad)

Rescales the x and y coordinates of each node by percent.

Parameters:

nodes - the nodes to rescale.

rescalePositions

public void rescalePositions(Set nodes,
                             double xpercent,
                             double ypercent,
                             int pad)

Rescales the x and y coordinates of each node by percent.

Parameters:

nodes - the nodes to rescale.

getX

public double getX(Vertex n)

getY

public double getY(Vertex n)

getCoordinates

public Coordinates getCoordinates(Node v)

incrementsAreDone

public boolean incrementsAreDone()

initialize_local_vertex

public void initialize_local_vertex(Vertex v)

initialize_local

public void initialize_local()

isIncremental

public boolean isIncremental()

rescalePositions

public static void rescalePositions(Set nodes,
                                    double percent,
                                    int pad,
                                    Map locations)

Rescales the x and y coordinates of each node by percent.

Parameters:

nodes - the nodes to rescale.

rescalePositions

public static void rescalePositions(Set nodes,
                                    int width,
                                    int height,
                                    Map locations)
