Perl OOP is simple. All you need is here
http://perldoc.perl.org/perltoot.html
And here
http://perldoc.perl.org/perltooc.html
Short intro:
Bless blesses a Datacontainer (scalar array or hash) with the name of
the package.
Block{
bless @array;
print [EMAIL PROTECTED];
}
Prints out something like
Block Array {87423649}
Instead of
Array {98649862}
Objects are build as arrays or hashes of "functions".
You can create constructors as you like.
Building a method new{} is the default.
it returns itself.
Class->Methode();
Class::Methode();
Or imported simple
Method();
Inheritance is automated, there are some special
Superclasses and Datacontainers (isa for example). Circular inheritance
is not possible.
Polymorphisim is not a problem, when you build your Object right.
There are SO MANY EXAMPLES at CPAN ACME that it is not possible to miss
them. www.cpan.org, search.cpan.org, http://perldoc.perl.org/
