Because AbstractEntityPersister implements Queryable (but EntityPersister does not), core does something like this to get access to Queryable interface methods: final Queryable queryable = (Queryable) sessionFactory.getEntityPersister( entityName ); Is this an acceptable way for an application to get access to an entity persister's Queryable interface or is there some explicit SPI that should be used?
