=head1 NAME

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

=head1 VERSION

version 2.2014

=head1 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] );
  }

=head1 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 L<MooseX::NonMoose::InsideOut> and L<MooseX::InsideOut>.

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

=for testing-SETUP use Test::Requires {
    'DateTime'                  => '0',
    'DateTime::Calendar::Mayan' => '0',
    'MooseX::NonMoose'          => '0.25',
};

=begin testing

my $dt = My::DateTime->new( year => 1970, month => 2, day => 24 );

can_ok( $dt, 'mayan_date' );
isa_ok( $dt->mayan_date, 'DateTime::Calendar::Mayan' );
is( $dt->mayan_date->date, '12.17.16.9.19', 'got expected mayan date' );

$dt->set( year => 2009 );
ok( ! $dt->has_mayan_date, 'mayan_date is cleared after call to ->set' );
