/**
 * Specifies the inheritance strategy to be used for an entity class
 * hierarchy. It is specified on 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 { ... }
 * 
* * @since 1.0 */ @Target({TYPE}) @Retention(RUNTIME) public @interface Inheritance { /** The strategy to be used for the entity inheritance hierarchy. */ InheritanceType strategy() default SINGLE_TABLE; }
