Moose::Cookbook::Basics::DateTime_ExtendingNonMooseParent - Extending a non-Moose parent class VERSION
version 2.1202 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. AUTHORS

Moose::Cookbook::Basics::Immutable - Making Moose fast by making your class immutable VERSION
version 2.1202 SYNOPSIS
package Point; use Moose; has 'x' => ( isa => 'Int', is => 'ro' ); has 'y' => ( isa => 'Int', is => 'rw' ); __PACKAGE__->meta->make_immutable; DESCRIPTION
The Moose metaclass API provides a "make_immutable()" method. Calling this method does two things to your class. First, it makes it faster. In particular, object construction and destruction are effectively "inlined" in your class, and no longer invoke the meta API. Second, you can no longer make changes via the metaclass API, such as adding attributes. In practice, this won't be a problem, as you rarely need to do this after first loading the class. CONCLUSION
We strongly recommend you make your classes immutable. It makes your code much faster, with a small compile-time cost. This will be especially noticeable when creating many objects. AUTHORS
