org.jpox.store.mapping.MultiMapping
All known Subclasses: org.jpox.store.mapping.ReferenceMapping, org.jpox.store.mapping.SubclassPCMapping,
| MultiMapping | | abstract public class MultiMapping extends JavaTypeMapping (Code) | | Mapping to represent multiple mappings.
This mapping can be used to represent, for example,
- a reference field (where there are multiple implementations)
- an element in a collection and the element has no table of its own, but multiple subclasses
- a FK of a PC field (where there may be multiple fields in the PK of the PC object)
