Right.
I was just concerned about creating readonly objets from readwrite
and vice-versa
It would be an extension of your readonly.
Given something like you already have, but with a comparable
readwrite class:
My::DataCentre
use base 'My::Rose::DB::Object';
My::DataCentre::ReadOnly
use base 'My::DataCentre ';
sub meta_class { 'My::Rose::DB::Metaclass::ReadOnly' }
or
My::DataCentre
use base 'My::Rose::DB::Object';
sub meta_class { 'My::Rose::DB::Metaclass::ReadOnly' }
My::DataCentre::Writer
use base 'My::DataCentre ';
sub meta_class { 'My::Rose::DB::Metaclass' }
I'd want to be able to create a readwrite object from a readonly, and
vice versa
instead of doing an object class mutation, i'd rather have new object
that is makes use of existing helper methods like clone or
init_with_xxx , in the context of a clone style call or instantiation
hook
basically, i want to have my cake and eat it too.
