Hi,

I learned OO Perl from the book "Object oriented Perl". Its pretty old so you can buy it second hand real cheap but its a jewel.

OO Perl is very easy, it uses 3 steps:

- To create a class, create a package

Just as you normally create a package, but do not export anything.

- To create methods, write subroutines

Methods are just subroutines, but instead of using the data in a class, they use the pointer to a blessed hash. Example: 

sub return_output
{
my ($self,%args) = @_;
return $self->{output};
}

- To create objects, bless a referent

The constructor blesses a reference to an anonymous hash and returns it. It uses function bless for this.

So its real easy, if I were you I would start with reading "Object oriented Perl" (as I did recently, I bought the book second hand for 5 euros but its worth much more).
