12 | * Designates a class whose mapping information is applied to the entities that inherit |
||
13 | * from it. A mapped superclass has no separate table defined for it. |
||
14 | * |
||
15 | * A class designated with the MappedSuperclass annotation can be mapped in the same way as |
||
16 | * an entity except that the mappings will apply only to its subclasses since no table exists |
||
17 | * for the mapped superclass itself. When applied to the subclasses the inherited mappings will |
||
18 | * apply in the context of the subclass tables. Mapping information may be overridden in such |
||
19 | * subclasses by using the AttributeOverride and AssociationOverride annotations or corresponding * |
||
20 | * XML elements. |
