All Implemented Interfaces:

Layouter, LayoutStage

public class ParentEdgeAugmentationStage

extends AbstractLayoutStage

This class can be used as a decorating stage for layout algorithms that cannot handle node groups. Before calling the core layout algorithms, this class will augment the graph structure. For each node that belongs to a group, a so-called "parent-edge" will be temporarily inserted into the graph.
