org.jpox.store.mapping.MultiMapping
org.jpox.store.mapping.ReferenceMapping
org.jpox.store.mapping.ObjectMapping
Mapping for Object fields. An Object field has a list of possible (PersistenceCapable) types that it represents and so any Object field is mapped to a series of ForeignKey columns in the datastore.
