All Implemented Interfaces:

java.io.Serializable

public class DomainObjectGraph
extends java.lang.Object
implements java.io.Serializable

A graph representing a hierarchy of domain objects and shapes. Each shape can have a number of subclasses and superclasses.
A subclass is an object that has the same number of primitives but more constraints between them.
A superclass is an object that has the same number of primitives but fewer constraints between them.
