This was ridiculously easy to implement to play around with as an
initial stab
the code is below , just to give you an idea.
i'll be playing around with this sort of stuff for a few days, then
pop something onto my svn if anyone wants to play around with it.
i really like this...
no, i ridiculously like this!
instead of passing results into various functions to handle maps,
foreach, and misc processing , I can just make a class for each
result list type, and toss my functions in there. plus with
inheritance chains, I can just inherit whatever methods i need from
other object classes.
this isn't for everyone -- in fact, it might be too OOP for most.
but i see A LOT of utility here :)
base-classes:
FindMeOn::Rose::DB::Object::ManagerResultProvider;
drop-in replacement
i just redefined get_objects -- so this wouldn't work with
make_manager_methods -- but I already call get_objects directly for
the performance boost :)
FindMeOn::Rose::DB::Object::ManagerResultList;
base result list class
application specific classes
FindMeOn::Rose::DB::Object::UseraccountFindmeon::ManagerList_A
has a sample routine
FindMeOn::Rose::DB::Object::UseraccountFindmeon::Manager
my $results= Rose::DB::Object::Manager->get_objects()
becomes
my $results= FindMeOn::Rose::DB::Object::ManagerResultProvider-
>get_objects( manager_result_class=>
'FindMeOn::Rose::DB::Object::UseraccountFindmeon::ManagerList_A' )
