OO, inheriting functions from other packagesby sschneid (Deacon) |

sschneid has asked for the wisdom of the Perl Monks concerning the following question:
This is an OO-based question that I've struggled with ever since I decided to dive into the OO-world, and still haven't really figured out. Maybe one of you can help my understanding. The basic set-up is as follows: Say I have three classes, Blah, Blah::DB, and Blah::Project: Blah: this is the main program. Blah::DB: contains all sorts of common functions I use to retrieve 'stuff' from a database. Blah::Project: contains functions that I use to deal with 'projects'. In Blah.pm, I'm doing the following: Which is peachy, because now I can do things like $db->tablelist(); and whatnot. The problem is: can I inherit the functions I use in Blah::DB into my Blah::Project package? Maybe all of my 'projects' are stored in a database, and I want to retrieve them and them store them in a 'project' object. I can't figure out a way to use any of the Blah::DB functions, however, without either: a) creating a new Blah::DB object from within Blah::Project, or b) pass my Blah::DB object to Blah::Project when I create a Blah::Project object (my $proj = Blah::Project->new($db);). Neither of these seem elegant. Can someone point me in the right direction? -s.
