MooseX::ABC - abstract base classes for Moose
version 0.01
package Shape;
use Moose;
use MooseX::ABC;
requires 'draw';
package Circle;
use Moose;
extends 'Shape';
sub draw {
# stuff
}
my $shape = Shape->new; # dies
my $circle = Circle->new; # succeeds
package Square;
use Moose;
extends 'Shape'; # dies, since draw is unimplemented
This module adds basic abstract base class functionality to Moose. Doing use MooseX::ABC turns the using class into an abstract class - it cannot be instantiated. It also allows you to mark certain methods in the class as "required", meaning that if a class inherits from this class without implementing that method, it will die at compile time.
Takes a list of methods that classes inheriting from this one must implement. If a class inherits from this class without implementing each method listed here, an error will be thrown when compiling the class.
Probably want a way to extend abstract classes without dying, making the inheriting class abstract.
No known bugs.
