The "Datamap" class?
Hi all,
I’m curious—what is the purpose of the “Datamap” class generated by Cayenne? I gave the docs an (admittedly superficial) glance but couldn't find anything about it. In all of my cayenne projects, it's just a class with one method “getInstance()”, that returns a lazily generated instance of itself. Can I delete it?

Correct. Datamap class may have more good stuff in the future, but for now it is of limited use. And IIRC we made its generation optional in the latest versions of 4.0 Modeler (and it is not generated from Ant / Maven unless you explicitly tell Cayenne to do it).

Yes. The only thing it does currently is it will contain constants for the
query names for any queries you define IN CayenneModeler.
