@Target(value=TYPE) @Retention(value=RUNTIME) public @interface ClassExtractor
The ClassExtractor must only be set on the root of an entity class or sub-hierarchy in which a different inheritance strategy is applied. The ClassExtractor can only be used with the SINGLE_TABLE and JOINED inheritance strategies.
If a ClassExtractor is used then a DiscriminatorColumn cannot be used. A DiscriminatorColumn also cannot be used on either the root or its subclasses.
In addition, for more complex configurations using a ClassExtractor and a SINGLE_TABLE strategy, the descriptor's withAllSubclasses and onlyInstances expressions should be set through the ClassExtractor's initialize method.
