Examples of OneToOneMapping

oracle.toplink.essentials.mappings.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. @author Sati @since TOPLink/Java 1.0
