# PODNAME: Moose::Cookbook::Basics::Immutable # ABSTRACT: Making Moose fast by making your class immutable __END__ =pod =encoding UTF-8 =head1 NAME Moose::Cookbook::Basics::Immutable - Making Moose fast by making your class immutable =head1 VERSION version 2.2207 =head1 SYNOPSIS package Point; use Moose; has 'x' => ( isa => 'Int', is => 'ro' ); has 'y' => ( isa => 'Int', is => 'rw' ); __PACKAGE__->meta->make_immutable; =head1 DESCRIPTION The Moose metaclass API provides a C<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. =head1 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. =head1 AUTHORS =over 4 =item * Stevan Little <stevan@cpan.org> =item * Dave Rolsky <autarch@urth.org> =item * Jesse Luehrs <doy@cpan.org> =item * Shawn M Moore <sartak@cpan.org> =item * יובל קוג'מן (Yuval Kogman) <nothingmuch@woobling.org> =item * Karen Etheridge <ether@cpan.org> =item * Florian Ragwitz <rafl@debian.org> =item * Hans Dieter Pearcey <hdp@cpan.org> =item * Chris Prather <chris@prather.org> =item * Matt S Trout <mstrout@cpan.org> =back =head1 COPYRIGHT AND LICENSE This software is copyright (c) 2006 by Infinity Interactive, Inc.
