Annotation Type AssociationOverride

@Target(value={TYPE,METHOD,FIELD})
@Retention(value=RUNTIME)
public @interface AssociationOverride

The AssociationOverride annotation is used to override a many-to-one or one-to-one mapping of property or field for an entity relationship.
The AssociationOverride annotation may be applied to an entity that extends a mapped superclass to override a many-to-one or one-to-one mapping defined by the mapped superclass. If the AssociationOverride annotation is not specified, the join column is mapped the same as in the original mapping.

Since:

JPA 1.0 version.
