We are experimenting with a new project board to help forum members make extra cash; because we have some very talented members, why not make some extra cash working from your computer. See toolbar at bottom of page.
Any ideas or comments?

Class::Virtual(3pm) User Contributed Perl Documentation Class::Virtual(3pm)NAME
Class::Virtual - Base class for virtual base classes.
SYNOPSIS
package My::Virtual::Idaho;
use base qw(Class::Virtual);
__PACKAGE__->virtual_methods(qw(new foo bar this that));
package My::Private::Idaho;
use base qw(My::Virtual::Idaho);
# Check to make sure My::Private::Idaho implemented everything
my @missing = __PACKAGE__->missing_methods;
die __PACKAGE__ . ' forgot to implement ' . join ', ', @missing
if @missing;
# If My::Private::Idaho forgot to implement new(), the program will
# halt and yell about that.
my $idaho = My::Private::Idaho->new;
# See what methods we're obligated to implement.
my @must_implement = __PACKAGE__->virtual_methods;
DESCRIPTION
This is a base class for implementing virtual base classes (what some people call an abstract class). Kinda kooky. It allows you to
explicitly declare what methods are virtual and that must be implemented by subclasses. This might seem silly, since your program will
halt and catch fire when an unimplemented virtual method is hit anyway, but there's some benefits.
The error message is more informative. Instead of the usual "Can't locate object method" error, you'll get one explaining that a virtual
method was left unimplemented.
Subclass authors can explicitly check to make sure they've implemented all the necessary virtual methods. When used as part of a
regression test, it will shield against the virtual method requirements changing out from under the subclass.
Finally, subclass authors can get an explicit list of everything they're expected to implement.
Doesn't hurt and it doesn't slow you down.
Methods
virtual_methods
Virtual::Class->virtual_methods(@virtual_methods);
my @must_implement = Sub::Class->virtual_methods;
This is an accessor to the list of virtual_methods. Virtual base classes will declare their list of virtual methods. Subclasses will
look at them. Once the virtual methods are set they cannot be undone.
missing_methods
my @missing_methods = Sub::Class->missing_methods;
Returns a list of methods Sub::Class has not yet implemented.
CAVEATS and BUGS
Autoloaded methods are currently not recognized. I have no idea how to solve this.
