Is there any current Apple documentation of EOF inheritance?
I know there are problems with horizontal inheritance, partially from
seeing it in the 5.2 release notes. I gather there are not problems with
single table inheritance. What about veritical inheritance? Any problems?
Can anyone shed light on the EOModelGroup.Delegate methods
relationshipForRow and subEntityForEntity? I don't really understand how
they are meant to be used, although it's clear they are relevant for
inheritance. If anyone has an example, or anything to say that's not found
in the reference for EOModelGroup.Delegate, that would be useful. I don't
understand what the dictionary parameter passed to subEntityForEntity is,
exactly. I also don't understand how you'd effectively use
relationshipForRow at all, how you'd need to set up your model for this to
be useful.
