Constructor Detail

CircleLayout

public CircleLayout()

Creates an instance which does not initialize the vertex locations.

CircleLayout

public CircleLayout(Graph<V,E> g)

Creates an instance for the specified graph.

Method Detail

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.

setVertexOrder

public void setVertexOrder(java.util.Comparator<V> comparator)

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

setVertexOrder

public void setVertexOrder(java.util.List<V> vertex_list)

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

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)
