IDaoFetchExistingPolymorphic Method

Performs the polymorphic entity fetch for the entity type of this DAO. It will produce an entity of that type or a subtype of that type, based on the values retrieved, or an empty entity if not found. The passed in fields object has its PK fields filled, which are used to produce a PK filter.
