UnitOfWorkTransformerValueHolder wraps a database-stored object and implements behavior to access it. The object is read from the database by invoking a user-specified transformer object. This value holder is used only in the unit of work. Most of the methods ignore the actual attribute values and are simply used to trigger instantiation.
