Hi Judah,
That sounds about right. So you'd have something like:
getContactByID(id):
// whatever arrangement you have for grabbing the right record out
of the database
query = select from Contact left join PhoneContact left join
EmailContact where ContactID = :id
if (query.contactType is "phone")
return CreateObject("PhoneContact").init(query.Field1,...)
else if (query.contactType is "email")
return CreateObject("EmailContact").init(query.Field1,...)
The PhoneContact and EmailContact objects would be inheriting some of those
fields from Contact. The main point is that you ask for a Contact, but what
you actually get back is on of the subtypes.
