NAME

       MooseX::ClassAttribute::Trait::Class - A trait for classes with class attributes

VERSION

       version 0.26

SYNOPSIS

	 for my $attr ( HasClassAttributes->meta()->get_all_class_attributes() )
	 {
	     print $attr->name();
	 }

DESCRIPTION

       This role adds awareness of class attributes to a metaclass object. It provides a set of introspection methods that largely parallel the
       existing attribute methods, except they operate on class attributes.

METHODS

       Every method provided by this role has an analogous method in "Class::MOP::Class" or "Moose::Meta::Class" for regular attributes.

   $meta->has_class_attribute($name)
   $meta->get_class_attribute($name)
   $meta->get_class_attribute_list()
       These methods operate on the current metaclass only.

   $meta->add_class_attribute(...)
       This accepts the same options as the Moose::Meta::Attribute "add_attribute()" method. However, if an attribute is specified as "required"
       an error will be thrown.

   $meta->remove_class_attribute($name)
       If the named class attribute exists, it is removed from the class, along with its accessor methods.

   $meta->get_all_class_attributes()
       This method returns a list of attribute objects for the class and all its parent classes.

   $meta->find_class_attribute_by_name($name)
       This method looks at the class and all its parent classes for the named class attribute.

   $meta->get_class_attribute_value($name)
   $meta->set_class_attribute_value($name, $value)
   $meta->set_class_attribute_value($name)
   $meta->clear_class_attribute_value($name)
       These methods operate on the storage for class attribute values, which is attached to the metaclass object.

       There's really no good reason for you to call these methods unless you're doing some deep hacking. They are named as public methods solely
       because they are used by other meta roles and classes in this distribution.

       See MooseX::ClassAttribute for details.

NAME

       Moose::Cookbook::Meta::Recipe1 - Welcome to the meta world (Why Go Meta?)

VERSION

       version 2.0205

SUMMARY

       You might want to read Moose::Manual::MOP if you haven't done so yet.

       If you've ever thought "Moose is great, but I wish it did X differently", then you've gone meta. The meta recipes demonstrate how to change
       and extend the way Moose works by extending and overriding how the meta classes (Moose::Meta::Class, Moose::Meta::Attribute, etc) work.

       The metaclass API is a set of classes that describe classes, roles, attributes, etc. The metaclass API lets you ask questions about a
       class, like "what attributes does it have?", or "what roles does the class do?"

       The metaclass system also lets you make changes to a class, for example by adding new methods or attributes.

       The interface presented by Moose.pm ("has", "with", "extends") is just a thin layer of syntactic sugar over the underlying metaclass
       system.

       By extending and changing how this metaclass system works, you can create your own Moose variant.

   Examples
       Let's say that you want to add additional properties to attributes. Specifically, we want to add a "label" property to each attribute, so
       we can write "My::Class->meta()->get_attribute('size')->label()". The first two recipes show two different ways to do this, one with a full
       meta-attribute subclass, and the other with an attribute trait.

       You might also want to add additional properties to your metaclass. For example, if you were writing an ORM based on Moose, you could
       associate a table name with each class via the class's metaclass object, letting you write "My::Class->meta()->table_name()".

SEE ALSO

       Many of the MooseX modules on CPAN implement metaclass extensions. A couple good examples include MooseX::Singleton and
       MooseX::AttributeHelpers. For a more complex example see Fey::ORM or Reaction.
