Constructor Details

CircleLayout

public CircleLayout(Graph<V,E> g)

Method Details

getRadius

public double getRadius()

Returns:

the radius of the circle.

setRadius

public void setRadius(double radius)

Sets the radius of the circle. Must be called before initialize() is called.

Parameters:

radius - the radius of the circle

setVertexOrder

public void setVertexOrder(Comparator<V> comparator)

Sets the order of the vertices in the layout according to the ordering specified by comparator.

Parameters:

comparator - the comparator to use to order the vertices

setVertexOrder

public void setVertexOrder(List<V> vertex_list)

Sets the order of the vertices in the layout according to the ordering of vertex_list.

Parameters:

vertex_list - a list specifying the ordering of the vertices

reset

public void reset()

initialize

public void initialize()

Description copied from interface: Layout

Initializes fields in the node that may not have been set during the constructor. Must be called before the iterations begin.

getCircleData

protected CircleLayout.CircleVertexData getCircleData(V v)
