=head1 NAME
MooseX::ClassAttribute::Trait::Role - A trait for roles with class attributes
=head1 VERSION
version 0.29
=head1 SYNOPSIS
for my $attr ( HasClassAttributes->meta()->get_all_class_attributes() )
{
print $attr->name();
}
=head1 DESCRIPTION
This role adds awareness of class attributes to a role metaclass object. It
provides a set of introspection methods that largely parallel the existing
attribute methods, except they operate on class attributes.
=head1 METHODS
Every method provided by this role has an analogous method in
C<Class::MOP::Class> or C<Moose::Meta::Class> for regular attributes.
=head2 $meta->has_class_attribute($name)
=head2 $meta->get_class_attribute($name)
=head2 $meta->get_class_attribute_list()
These methods are exactly like their counterparts in
L<MooseX::ClassAttribute::Trait::Class>.
=head2 $meta->add_class_attribute(...)
This accepts the same options as the L<Moose::Meta::Attribute>
C<add_attribute()> method. However, if an attribute is specified as
"required" an error will be thrown.
=head2 $meta->remove_class_attribute($name)
If the named class attribute exists, it is removed from the role.
=head1 BUGS
See L<MooseX::ClassAttribute> for details.
Bugs may be submitted through L<the RT bug tracker|http://rt.cpan.org/Public/Dist/Display.html?Name=MooseX-ClassAttribute>
(or L<bug-moosex-classattribute@rt.cpan.org|mailto:bug-moosex-classattribute@rt.cpan.org>).
I am also usually active on IRC as 'drolsky' on C<irc://irc.perl.org>.
