.SH "DESCRIPTION"
.IX Header "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.
.SH "METHODS"
.IX Header "METHODS"
Every method provided by this role has an analogous method in
\&\f(CW\*(C`Class::MOP::Class\*(C'\fR or \f(CW\*(C`Moose::Meta::Class\*(C'\fR for regular attributes.
.ie n .SS "$meta\->has_class_attribute($name)"
.el .SS "\f(CW$meta\fP\->has_class_attribute($name)"
.IX Subsection "$meta->has_class_attribute($name)"
.ie n .SS "$meta\->get_class_attribute($name)"
.el .SS "\f(CW$meta\fP\->get_class_attribute($name)"
.IX Subsection "$meta->get_class_attribute($name)"
.ie n .SS "$meta\->\fBget_class_attribute_list()\fP"
.el .SS "\f(CW$meta\fP\->\fBget_class_attribute_list()\fP"
.IX Subsection "$meta->get_class_attribute_list()"
These methods are exactly like their counterparts in
MooseX::ClassAttribute::Trait::Class.
.ie n .SS "$meta\->add_class_attribute(...)"
.el .SS "\f(CW$meta\fP\->add_class_attribute(...)"
.IX Subsection "$meta->add_class_attribute(...)"
This accepts the same options as the Moose::Meta::Attribute
\&\f(CW\*(C`add_attribute()\*(C'\fR method. However, if an attribute is specified as
\&\*(L"required\*(R" an error will be thrown.
.ie n .SS "$meta\->remove_class_attribute($name)"
.el .SS "\f(CW$meta\fP\->remove_class_attribute($name)"
.IX Subsection "$meta->remove_class_attribute($name)"
If the named class attribute exists, it is removed from the role.
