VERSION

SYNOPSIS

           package My::Class;

           use Moose;
           use MooseX::ClassAttribute;

           class_has 'Cache' =>
               ( is      => 'rw',
                 isa     => 'HashRef',
                 default => sub { {} },
               );

           __PACKAGE__->meta()->make_immutable();

           no Moose;
           no MooseX::ClassAttribute;

           # then later ...

           My::Class->Cache()->{thing} = ...;

DESCRIPTION

       This module allows you to declare class attributes in exactly the same way as object attributes, using
       "class_has()" instead of "has()".

       You can use any feature of Moose's attribute declarations, including overriding a parent's attributes,
       delegation ("handles"), attribute traits, etc. All features should just work. The one exception is the
       "required" flag, which is not allowed for class attributes.

       The accessor methods for class attribute may be called on the class directly, or on objects of that
       class. Passing a class attribute to the constructor will not set that attribute.

FUNCTIONS

       This class exports one function when you use it, "class_has()". This works exactly like Moose's "has()",
       but it declares class attributes.

       One little nit is that if you include "no Moose" in your class, you won't remove the "class_has()"
       function. To do that you must include "no MooseX::ClassAttribute" as well. Or you can just use
       namespace::autoclean instead.

   Implementation and Immutability
       This module will add a role to your class's metaclass, See MooseX::ClassAttribute::Trait::Class for
       details. This role provides introspection methods for class attributes.

       Class attributes themselves do the MooseX::ClassAttribute::Trait::Attribute role.

   Cooperation with Metaclasses and Traits
       This module should work with most attribute metaclasses and traits, but it's possible that conflicts
       could occur. This module has been tested to work with Moose's native traits.

   Class Attributes in Roles
       You can add a class attribute to a role. When that role is applied to a class, the class will have the
       relevant class attributes added. Note that attribute defaults will be calculated when the class attribute
       is composed into the class.

DONATIONS

       If you'd like to thank me for the work I've done on this module, please consider making a "donation" to
       me via PayPal. I spend a lot of free time creating free software, and would appreciate any support you'd
       care to offer.

       Please note that I am not suggesting that you must do this in order for me to continue working on this
       particular software. I will continue to do so, inasmuch as I have in the past, for as long as it
       interests me.

       Similarly, a donation made in this way will probably not make me work on this software much more, unless
       I get so many donations that I can consider working on free software full time, which seems unlikely at
       best.

       To donate, log into PayPal and send money to autarch@urth.org or use the button on this page:
