713 Moose::Meta::Role - The Moose Role metaclass
717 This class is a subclass of L<Class::MOP::Module> that provides
718 additional Moose-specific functionality.
720 It's API looks a lot like L<Moose::Meta::Class>, but internally it
721 implements many things differently. This may change in the future.
725 C<Moose::Meta::Role> is a subclass of L<Class::MOP::Module>.
733 =item B<< Moose::Meta::Role->initialize($role_name) >>
735 This method creates a new role object with the provided name.
737 =item B<< Moose::Meta::Role->combine( [ $role => { ... } ], [ $role ], ... ) >>
739 This method accepts a list of array references. Each array reference
740 should contain a role name as its first element. The second element is
741 an optional hash reference. The hash reference can contain C<exclude>
742 and C<alias> keys to control how methods are composed from the role.
744 The return value is a new L<Moose::Meta::Role::Composite> that
745 represents the combined roles.
747 =item B<< Moose::Meta::Role->create($name, %options) >>
749 This method is identical to the L<Moose::Meta::Class> C<create>
752 =item B<< Moose::Meta::Role->create_anon_role >>
754 This method is identical to the L<Moose::Meta::Class>
755 C<create_anon_class> method.
757 =item B<< $metarole->is_anon_role >>
759 Returns true if the role is an anonymous role.
763 =head2 Role application
767 =item B<< $metarole->apply( $thing, @options ) >>
769 This method applies a role to the given C<$thing>. That can be another
770 L<Moose::Meta::Role>, object, a L<Moose::Meta::Class> object, or a
771 (non-meta) object instance.
773 The options are passed directly to the constructor for the appropriate
774 L<Moose::Meta::Role::Application> subclass.
776 Note that this will apply the role even if the C<$thing> in question already
777 C<does> this role. L<Moose::Util/does_role> is a convenient wrapper for
778 finding out if role application is necessary.
782 =head2 Roles and other roles
786 =item B<< $metarole->get_roles >>
788 This returns an array reference of roles which this role does. This
789 list may include duplicates.
791 =item B<< $metarole->calculate_all_roles >>
793 This returns a I<unique> list of all roles that this role does, and
794 all the roles that its roles do.
796 =item B<< $metarole->does_role($role_name) >>
798 Given a role I<name>, returns true if this role does the given
801 =item B<< $metarole->add_role($role) >>
803 Given a L<Moose::Meta::Role> object, this adds the role to the list of
804 roles that the role does.
806 =item B<< $metarole->get_excluded_roles_list >>
808 Returns a list of role names which this role excludes.
810 =item B<< $metarole->excludes_role($role_name) >>
812 Given a role I<name>, returns true if this role excludes the named
815 =item B<< $metarole->add_excluded_roles(@role_names) >>
817 Given one or more role names, adds those roles to the list of excluded
824 The methods for dealing with a role's methods are all identical in API
825 and behavior to the same methods in L<Class::MOP::Class>.
829 =item B<< $metarole->method_metaclass >>
831 Returns the method metaclass name for the role. This defaults to
832 L<Moose::Meta::Role::Method>.
834 =item B<< $metarole->get_method($name) >>
836 =item B<< $metarole->has_method($name) >>
838 =item B<< $metarole->add_method( $name, $body ) >>

846 These methods are all identical to the methods of the same name in
853 As with methods, the methods for dealing with a role's attribute are
854 all identical in API and behavior to the same methods in
855 L<Class::MOP::Class>.
857 However, attributes stored in this class are I<not> stored as
858 objects. Rather, the attribute definition is stored as a hash
859 reference. When a role is composed into a class, this hash reference
860 is passed directly to the metaclass's C<add_attribute> method.
862 This is quite likely to change in the future.

880 =head2 Required methods
884 =item B<< $metarole->get_required_method_list >>
886 Returns the list of methods required by the role.
888 =item B<< $metarole->requires_method($name) >>
890 Returns true if the role requires the named method.
892 =item B<< $metarole->add_required_methods(@names >>
894 Adds the named methods to the roles list of required methods.
896 =item B<< $metarole->remove_required_methods(@names) >>
898 Removes the named methods to the roles list of required methods.
902 =head2 Method modifiers
904 These methods act like their counterparts in L<Class::Mop::Class> and
905 L<Moose::Meta::Class>.
907 However, method modifiers are simply stored internally, and are not
908 applied until the role itself is applied to a class.
912 =item B<< $metarole->add_after_method_modifier($method_name, $method) >>
914 =item B<< $metarole->add_around_method_modifier($method_name, $method) >>
916 =item B<< $metarole->add_before_method_modifier($method_name, $method) >>
918 =item B<< $metarole->add_override_method_modifier($method_name, $method) >>
920 These methods all add an appropriate modifier to the internal list of
923 =item B<< $metarole->has_after_method_modifiers >>
925 =item B<< $metarole->has_around_method_modifiers >>
927 =item B<< $metarole->has_before_method_modifiers >>
929 =item B<< $metarole->has_override_method_modifier >>
931 Return true if the role has any modifiers of the given type.
933 =item B<< $metarole->get_after_method_modifiers($method_name) >>
935 =item B<< $metarole->get_around_method_modifiers($method_name) >>
937 =item B<< $metarole->get_before_method_modifiers($method_name) >>
939 Given a method name, returns a list of the appropriate modifiers for
942 =item B<< $metarole->get_override_method_modifier($method_name) >>
944 Given a method name, returns the override method modifier for that
945 method, if it has one.
953 =item B<< Moose::Meta::Role->meta >>
955 This will return a L<Class::MOP::Class> instance for this class.
