Hi,
I would not like to take away the normal doSelect (Criteria) method for two
reasons. The first is that you would break some code if the newly generated
classes does not have that method and second you'll need to type the
class-name every time you call doSelect.
I can see the usefulness of this approach so I think we should overload the
doSelect() method in the Peer class that so that it can optionally take the
class-name as a parameter. On top of that I think we should add a static
final string to the Peer class that defines the default class-name that will
be instantiated if you do not supply a class-name with your doSelect.
Anybody as any other thoughts on this?
My ISP made it impossible for me to do any CVS updates or commits :-( I'll
try and commit the template based Torque tomorrow (Friday). It'll be easy
to add this code to the template...
