No, not quite. It depends on whether you will be using Address and Person objects independently of each other, or whether the Address object is a dependent object that will only ever be used in the context of it's Person. If you're going for the latter, then you do want EV (although you can kinda fake it with what i wrote above).
If you want proper EV though, you'll have to wait for Piotr's work. The difference will matter in terms of how objects are fetched and saved in particular. EV provides much clearer semantics for it, and changing the address on a person record, and someone's email will only require one update to be fired to the database, as opposed to two in the case of what i wrote above. -T On Tue, Apr 12, 2011 at 10:44 AM, Jean Baldessar <jean.baldes...@gmail.com>wrote: > I was looking for a solution like the @Embedded from Java Persistence API. > So, at first glance the name EmbeddedValue looked like the kind of feature > that im looking after. > Ted solution seems to work to, but I dont realy understand the diference > between the Ted and Piotr solutions. > > They are not the same thing? > > 2011/4/12 Ted Han <t...@knowtheory.net> > >> Erm, what he's talking about isn't quite EV though is it?
