Object Oriented Perl

Backround

• Object Orientation is a programming and design paradigm that gives a nice clean way to combine the attributes and the actions of an "object" into a single place within the code. Note that this point is a gross oversimplification, but it is at least an accurate gross oversimplification.
• The CGI perl packages we will be using for our CGI development have both an object oriented and a standard procedural interface available. The OO interface is superior, and it is the one we will use, but be aware if you are doing maintenance, you may run across the procedural interface.
• Before we jump straight into the CGI OO interface, lets spend first develop a few OO modules of our own.
• This will better help us understand what things we learn are standard Perl OO, and what things we learn are supplied by the CGI libraries.
• Much of the overview supplied on the following pages will be pulled from the excellent "perltoot" object oriented tutorial. Type man perltoot on any self respecting Unix system for the full tutorial.
