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 beforeinitialize()
is called.- Parameters:
radius
- the radius of the circle
-
setVertexOrder
public void setVertexOrder(java.util.Comparator<V> comparator)
Sets the order of the vertices in the layout according to the ordering specified bycomparator
.- Parameters:
comparator
- the comparator to use to order the vertices
-
setVertexOrder
public void setVertexOrder(java.util.List<V> vertex_list)
Sets the order of the vertices in the layout according to the ordering ofvertex_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.
