Examples of VariableOneToOneMapping

org.eclipse.persistence.mappings.VariableOneToOneMapping

Purpose: Variable one to one mappings are used to represent a pointer references between a java object and an implementer of an interface. This mapping 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 a foreign key and a type code. @author Sati @since TOPLink/Java 2.0
