[hibernate-dev] can a mapped super class extends from an entity?
test is org.hibernate.jpa.test.metadata.MetadataTest and root class is
org.hibernate.jpa.test.metadata.Thing
basically here is a hierarchy like :
Entity -> MappedSuperclass -> Entity -> MappedSuperclass -> Object (//not an
entity but in between mapped superclass and entity) -> MappedSuperclass
in the metamodel branch
org.hibernate.metamodel.internal.source.annotations.util.EntityHierarchyBuilder#processHierarchy
if ( !isEntityClass( subClassInfo ) ) {
if ( JandexHelper.containsSingleAnnotation( subClassInfo, JPADotNames.EMBEDDABLE ) )
{
throw new AnnotationException( "An embeddable cannot extend an entity: " +
subClassInfo );
}
if ( JandexHelper.containsSingleAnnotation( subClassInfo,
JPADotNames.MAPPED_SUPERCLASS ) ) {
throw new AnnotationException( "A mapped superclass cannot extend an entity:
" + subClassInfo );
}
continue;
}
