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

VERSION
    version 2.2200

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.
