Class Sugiyama

java.lang.Object
  pedviz.algorithms.Sugiyama

All Implemented Interfaces:

java.lang.Runnable, java.util.EventListener, javax.swing.event.ChangeListener, Algorithm

public class Sugiyama
extends java.lang.Object
implements Algorithm, javax.swing.event.ChangeListener

This class combines all steps that are necessary to create a layout for a Graph object. It implements the Algorithm interface, so it's possible to visualize the progress with the DialogProgress class.
