public class RandomGraphLayout

extends DefaultGraphLayout

implements java.lang.Cloneable, GraphLayout

RandomGraphLayout provides a class for graph layout algorithms. All vertices are set on random positions. Coordinates are choosen from [-200, 200] x [-200, 200].

Constructor Summary

RandomGraphLayout()
Empty constructor.

RandomGraphLayout(RandomGraphLayout other)
A Copy-Constructor.

Method Summary

void	calculation(java.util.Enumeration objects) Calculate a layout based on a Vertex enumeration.
void	calculation(jdsl.graph.api.InspectableGraph graph) Calculate a layout based on given graph graph.
java.lang.Object	clone() Creates and returns a copy of this object.

Specified by:

calculation in interface GraphLayout

Parameters:

graph - given graph

Overrides:

calculation in class DefaultGraphLayout

Specified by:

calculation in interface GraphLayout

Parameters:

vertices - given Vertex enumeration

Overrides:
