# NAME
MooseX::AbstractMethod - Declare methods requirements that must be satisfied
# VERSION
This document describes version 0.005 of MooseX::AbstractMethod - released July 02, 2015 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](https://metacpan.org/pod/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.

Please note **I do not expect to be gittip'ed or flattr'ed for this work**,
rather **it is simply a very pleasant surprise**. I largely create and release
works like this because I need them or I find it enjoyable; however, don't let
that stop you if you feel like it ;)
