java.lang.Objectorg.eclipse.persistence.mappings.DatabaseMapping
org.eclipse.persistence.mappings.ForeignReferenceMapping
org.eclipse.persistence.mappings.ObjectReferenceMapping
org.eclipse.persistence.mappings.OneToOneMapping
public class OneToOneMapping
Purpose: One to one mappings are used to represent a pointer references between two java objects. This mappings is usually represented by a single pointer (stored in an instance variable) between the source and target objects. In the relational database tables, these mappings are normally implemented using foreign keys.
