public class EntityAssociation
Describes the relationship between two Entity Objects. An association selects attributes from source and destination Entity Objects. Typically, these attributes represent key fields in a database table, but an association can be defined using any Entity Object attributes. Although an association identifies a source and destination end, the association can be navigated in either direction. Associations have package scope.
The EntityAssociation class determines the content of the AssociationDefImpl
attributes on the Entity definitions. The AssociationDefImpl attributes are the attributes at the source Entity and the destination Entity. There are two AssociationDefImpls for each EntityAssociation. For example, in the case of an association between Dept and Emp, Dept will have one AssociationDefImpl attribute for Emp; Emp will have one AssociationDefImpl attribute for Dept. The EntityAssociation links the two AssociationDefImpls.
An instance of the EntityAssociation class maps to the XML file for the association. At runtime, when the XML for the EntityAssociation is read, the framework creates the two AssociationDefImpls and determines whether they are source or destination attributes.
