NAME ^

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

VERSION ^

version 2.1210

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.
