Annotation Interface Inheritance

@Target(TYPE)
@Retention(RUNTIME)
public @interface Inheritance

Specifies the inheritance mapping strategy for the entity class hierarchy which descends from the annotated entity class.

This annotation must be applied to the entity class that is the root of the entity class hierarchy. If the Inheritance annotation is not specified, or if no inheritance type is specified for an entity class hierarchy, the SINGLE_TABLE mapping strategy is used.

Example:

@Entity
@Inheritance(strategy = JOINED)
public class Customer { ... }

@Entity
public class ValuedCustomer extends Customer { ... }
