Moose::Cookbook::Basics::DateTime_ExtendingNonMooseParent - Extending a non-Moose parent class
version 2.1205
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] ); }
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.
