681 |  |  |  |  |
682 |  |  |  |  | Moose::Meta::Role - The Moose Role metaclass
683 |  |  |  |  |
684 |  |  |  |  | =head1 DESCRIPTION
685 |  |  |  |  |
686 |  |  |  |  | This class is a subclass of L<Class::MOP::Module> that provides
687 |  |  |  |  | additional Moose-specific functionality.
688 |  |  |  |  |
689 |  |  |  |  | It's API looks a lot like L<Moose::Meta::Class>, but internally it
690 |  |  |  |  | implements many things differently. This may change in the future.
691 |  |  |  |  |
692 |  |  |  |  | =head1 INHERITANCE
693 |  |  |  |  |
694 |  |  |  |  | C<Moose::Meta::Role> is a subclass of L<Class::MOP::Module>.
695 |  |  |  |  |
696 |  |  |  |  | =head1 METHODS
697 |  |  |  |  |
698 |  |  |  |  | =head2 Construction

701 |  |  |  |  |
702 |  |  |  |  | =item B<< Moose::Meta::Role->initialize($role_name) >>
703 |  |  |  |  |
704 |  |  |  |  | This method creates a new role object with the provided name.
705 |  |  |  |  |
706 |  |  |  |  | =item B<< Moose::Meta::Role->combine( [ $role => { ... } ], [ $role ], ... ) >>
707 |  |  |  |  |
708 |  |  |  |  | This method accepts a list of array references. Each array reference
709 |  |  |  |  | should contain a role name or L<Moose::Meta::Role> object as its first element. The second element is
710 |  |  |  |  | an optional hash reference. The hash reference can contain C<-excludes>
711 |  |  |  |  | and C<-alias> keys to control how methods are composed from the role.
712 |  |  |  |  |
713 |  |  |  |  | The return value is a new L<Moose::Meta::Role::Composite> that
714 |  |  |  |  | represents the combined roles.
715 |  |  |  |  |
716 |  |  |  |  | =item B<< $metarole->composition_class_roles >>
717 |  |  |  |  |
718 |  |  |  |  | When combining multiple roles using C<combine>, this method is used to obtain a
719 |  |  |  |  | list of role names to be applied to the L<Moose::Meta::Role::Composite>
720 |  |  |  |  | instance returned by C<combine>. The default implementation returns an empty
721 |  |  |  |  | list. Extensions that need to hook into role combination may wrap this method
722 |  |  |  |  | to return additional role names.
723 |  |  |  |  |
724 |  |  |  |  | =item B<< Moose::Meta::Role->create($name, %options) >>
725 |  |  |  |  |
726 |  |  |  |  | This method is identical to the L<Moose::Meta::Class> C<create>
727 |  |  |  |  | method.
728 |  |  |  |  |
729 |  |  |  |  | =item B<< Moose::Meta::Role->create_anon_role >>
730 |  |  |  |  |
731 |  |  |  |  | This method is identical to the L<Moose::Meta::Class>
732 |  |  |  |  | C<create_anon_class> method.
733 |  |  |  |  |
734 |  |  |  |  | =item B<< $metarole->is_anon_role >>
735 |  |  |  |  |
736 |  |  |  |  | Returns true if the role is an anonymous role.

743 |  |  |  |  |
744 |  |  |  |  | =item B<< $metarole->apply( $thing, @options ) >>
745 |  |  |  |  |
746 |  |  |  |  | This method applies a role to the given C<$thing>. That can be another
747 |  |  |  |  | L<Moose::Meta::Role>, object, a L<Moose::Meta::Class> object, or a
748 |  |  |  |  | (non-meta) object instance.
749 |  |  |  |  |
750 |  |  |  |  | The options are passed directly to the constructor for the appropriate
751 |  |  |  |  | L<Moose::Meta::Role::Application> subclass.
752 |  |  |  |  |
753 |  |  |  |  | Note that this will apply the role even if the C<$thing> in question already
754 |  |  |  |  | C<does> this role. L<Moose::Util/does_role> is a convenient wrapper for
755 |  |  |  |  | finding out if role application is necessary.

762 |  |  |  |  |
763 |  |  |  |  | =item B<< $metarole->get_roles >>
764 |  |  |  |  |
765 |  |  |  |  | This returns an array reference of roles which this role does. This
766 |  |  |  |  | list may include duplicates.
767 |  |  |  |  |
768 |  |  |  |  | =item B<< $metarole->calculate_all_roles >>
769 |  |  |  |  |
770 |  |  |  |  | This returns a I<unique> list of all roles that this role does, and
771 |  |  |  |  | all the roles that its roles do.
772 |  |  |  |  |
773 |  |  |  |  | =item B<< $metarole->does_role($role) >>
774 |  |  |  |  |
775 |  |  |  |  | Given a role I<name> or L<Moose::Meta::Role> object, returns true if this role
776 |  |  |  |  | does the given role.
777 |  |  |  |  |
778 |  |  |  |  | =item B<< $metarole->add_role($role) >>
779 |  |  |  |  |
780 |  |  |  |  | Given a L<Moose::Meta::Role> object, this adds the role to the list of
781 |  |  |  |  | roles that the role does.
782 |  |  |  |  |
783 |  |  |  |  | =item B<< $metarole->get_excluded_roles_list >>
784 |  |  |  |  |
785 |  |  |  |  | Returns a list of role names which this role excludes.
786 |  |  |  |  |
787 |  |  |  |  | =item B<< $metarole->excludes_role($role_name) >>
788 |  |  |  |  |
789 |  |  |  |  | Given a role I<name>, returns true if this role excludes the named
790 |  |  |  |  | role.
791 |  |  |  |  |
792 |  |  |  |  | =item B<< $metarole->add_excluded_roles(@role_names) >>
793 |  |  |  |  |
794 |  |  |  |  | Given one or more role names, adds those roles to the list of excluded
795 |  |  |  |  | roles.

800 |  |  |  |  |
801 |  |  |  |  | The methods for dealing with a role's methods are all identical in API
802 |  |  |  |  | and behavior to the same methods in L<Class::MOP::Class>.
803 |  |  |  |  |
804 |  |  |  |  | =over 4
805 |  |  |  |  |
806 |  |  |  |  | =item B<< $metarole->method_metaclass >>
807 |  |  |  |  |
808 |  |  |  |  | Returns the method metaclass name for the role. This defaults to
809 |  |  |  |  | L<Moose::Meta::Role::Method>.
810 |  |  |  |  |
811 |  |  |  |  | =item B<< $metarole->get_method($name) >>

818 |  |  |  |  |
819 |  |  |  |  | =item B<< $metarole->find_method_by_name($name) >>
820 |  |  |  |  |
821 |  |  |  |  | These methods are all identical to the methods of the same name in
822 |  |  |  |  | L<Class::MOP::Package>

826 |  |  |  |  | =head2 Attributes
827 |  |  |  |  |
828 |  |  |  |  | As with methods, the methods for dealing with a role's attribute are
829 |  |  |  |  | all identical in API and behavior to the same methods in
830 |  |  |  |  | L<Class::MOP::Class>.
831 |  |  |  |  |
832 |  |  |  |  | However, attributes stored in this class are I<not> stored as
833 |  |  |  |  | objects. Rather, the attribute definition is stored as a hash
834 |  |  |  |  | reference. When a role is composed into a class, this hash reference
835 |  |  |  |  | is passed directly to the metaclass's C<add_attribute> method.
836 |  |  |  |  |
837 |  |  |  |  | This is quite likely to change in the future.

860 |  |  |  |  |
861 |  |  |  |  | =item B<< $metarole->requires_method($name) >>
862 |  |  |  |  |

874 |  |  |  |  |
875 |  |  |  |  | Instantiate the parameters as a L<Moose::Meta::Role::Method::Conflicting>
876 |  |  |  |  | object, then add it to the required method list.

881 |  |  |  |  |
882 |  |  |  |  | These methods act like their counterparts in L<Class::MOP::Class> and
883 |  |  |  |  | L<Moose::Meta::Class>.
884 |  |  |  |  |
885 |  |  |  |  | However, method modifiers are simply stored internally, and are not
886 |  |  |  |  | applied until the role itself is applied to a class.
887 |  |  |  |  |
