NAME

Moose::Cookbook::Basics::DateTime_ExtendingNonMooseParent - Extending a non-Moose parent class

VERSION

version 2.2100

SYNOPSIS

package My::DateTime;

use Moose;
use MooseX::NonMoose;
use DateTime::Calendar::Mayan;
extends qw( DateTime );

has 'mayan_date' => (
    is        => 'ro',
    isa       => 'DateTime::Calendar::Mayan',
    init_arg  => undef,
    lazy      => 1,
    builder   => '_build_mayan_date',
    clearer   => '_clear_mayan_date',
    predicate => 'has_mayan_date',
);

after 'set' => sub {
    $_[0]->_clear_mayan_date;
};

sub _build_mayan_date {
    DateTime::Calendar::Mayan->from_object( object => $_[0] );
}

DESCRIPTION

This recipe demonstrates how to use Moose to subclass a parent which is not Moose based. This recipe only works if the parent class uses a blessed hash reference for object instances. If your parent is doing something funkier, you should check out MooseX::NonMoose::InsideOut and MooseX::InsideOut.

The meat of this recipe is contained in MooseX::NonMoose, which does all the grunt work for you.
