Hi Linux gurus,
My boss had asked me to setup a box consisting of this 3 OS (CentOS, Fedora, RedHat) for autopatching. So, whenever there is new patches for CentOS from the internet, this box will grab it, implement it, if tested ok and approved, the patches will then be push to Production... (23 Replies)

Class::Virtually::Abstract(3pm) User Contributed Perl Documentation Class::Virtually::Abstract(3pm)NAME
Class::Virtually::Abstract - Compile-time enforcement of Class::Virtual
SYNOPSIS
package My::Virtual::Idaho;
use base qw(Class::Virtually::Abstract);
__PACKAGE__->virtual_methods(qw(new foo bar this that));
package My::Private::Idaho;
use base qw(My::Virtual::Idaho);
sub new { ... }
sub foo { ... }
sub bar { ... }
sub this { ... }
# oops, forgot to implement that()!! Whatever will happen?!
# Meanwhile, in another piece of code!
# KA-BLAM! My::Private::Idaho fails to compile because it didn't
# fully implement My::Virtual::Idaho.
use My::Private::Idaho;
DESCRIPTION
This subclass of Class::Virtual provides compile-time enforcement. That means subclasses of your virtual class are required to implement
all virtual methods or else it will not compile.
BUGS and CAVEATS
Because this relies on import() it is important that your classes are used instead of required. This is a problem, and I'm trying to
figure a way around it.
Also, if a subclass defines its own import() routine (I've done it) Class::Virtually::Abstract's compile-time checking is defeated.
Got to think of a better way to do this besides import().
