NAME

MooseX::ABC - abstract base classes for Moose

VERSION

version 0.02

SYNOPSIS

  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

DESCRIPTION

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.

EXPORTS

requires METHOD_NAMES

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.

TODO

Probably want a way to extend abstract classes without dying, making the inheriting class abstract.

BUGS

No known bugs.
