MooseX::AbstractMethod(3)

NAME
MooseX::AbstractMethod - Declare methods requirements that must be satisfied

VERSION
This document describes version 0.004 of MooseX::AbstractMethod - released August 31, 2012 as part of MooseX-AbstractMethod.

SYNOPSIS
    use Moose;
    use MooseX::Abstract;

    requires 'bar';

    # synonm to 'requires'
    abstract 'foo';

DESCRIPTION
This extensions allows classes to flag certain methods as being required to be implemented by a subclass, much as a Moose::Role does with 'requires'.

USAGE
As in the synopsis, simply mark certain methods as being required by subclasses by passing their names to "abstract" or "requires". This will cause a method of the same name to be installed in the class that will die horribly if it's ever called. Additionally, when a class is made immutable, all of its methods are checked to see if they're marked as abstract; if any abstract methods exists that were not created in the current class, we die horribly.

Checking for method satisfaction on make_immutable isn't perfect, but AFAICT it's the most reasonable approach possible at the moment. (Corrections welcome.)

NEW SUGAR

  abstract
abstract() allows one to declare a method dependency that must be satisfied by a subclass before it is invoked, and before the subclass is made immutable.

    abstract 'method_name_that_must_be_satisfied';

  requires
requires() is a synonym for abstract() and works in the way you'd expect.
