      org.eigenbase.jmi.JmiAssocEdge

All Implemented Interfaces:

Serializable, Cloneable

public class JmiAssocEdge
extends org.jgrapht.graph.DefaultEdge

JmiAssocEdge represents an association in a JMI model. The source vertex is the class for the source end and the target vertex is the class for the target end, where

• if an end is composite, it is the source end
• else if an end has multiplicity > 1, it is the target end if the other end has multiplicity <= 1
• else if an end is ordered, it is the target end
• otherwise, the first end is the source end and the second end is the target end
