709 Moose::Meta::Role - The Moose Role metaclass
713 This class is a subclass of L<Class::MOP::Module> that provides
714 additional Moose-specific functionality.
716 It's API looks a lot like L<Moose::Meta::Class>, but internally it
717 implements many things differently. This may change in the future.
721 C<Moose::Meta::Role> is a subclass of L<Class::MOP::Module>.
729 =item B<< Moose::Meta::Role->initialize($role_name) >>
731 This method creates a new role object with the provided name.
733 =item B<< Moose::Meta::Role->combine( [ $role => { ... } ], [ $role ], ... ) >>
735 This method accepts a list of array references. Each array reference
736 should contain a role name or L<Moose::Meta::Role> object as its first element. The second element is
737 an optional hash reference. The hash reference can contain C<-excludes>
738 and C<-alias> keys to control how methods are composed from the role.
740 The return value is a new L<Moose::Meta::Role::Composite> that
741 represents the combined roles.
743 =item B<< $metarole->composition_class_roles >>
745 When combining multiple roles using C<combine>, this method is used to obtain a
746 list of role names to be applied to the L<Moose::Meta::Role::Composite>
747 instance returned by C<combine>. The default implementation returns an empty
748 list. Extensions that need to hook into role combination may wrap this method
749 to return additional role names.
751 =item B<< Moose::Meta::Role->create($name, %options) >>
753 This method is identical to the L<Moose::Meta::Class> C<create>
756 =item B<< Moose::Meta::Role->create_anon_role >>
758 This method is identical to the L<Moose::Meta::Class>
759 C<create_anon_class> method.
761 =item B<< $metarole->is_anon_role >>
763 Returns true if the role is an anonymous role.
765 =item B<< $metarole->consumers >>
767 Returns a list of names of classes and roles which consume this role.
771 =head2 Role application
775 =item B<< $metarole->apply( $thing, @options ) >>
777 This method applies a role to the given C<$thing>. That can be another
778 L<Moose::Meta::Role>, object, a L<Moose::Meta::Class> object, or a
779 (non-meta) object instance.
781 The options are passed directly to the constructor for the appropriate
782 L<Moose::Meta::Role::Application> subclass.
784 Note that this will apply the role even if the C<$thing> in question already
785 C<does> this role. L<Moose::Util/does_role> is a convenient wrapper for
786 finding out if role application is necessary.
790 =head2 Roles and other roles
794 =item B<< $metarole->get_roles >>
796 This returns an array reference of roles which this role does. This
797 list may include duplicates.
799 =item B<< $metarole->calculate_all_roles >>
801 This returns a I<unique> list of all roles that this role does, and
802 all the roles that its roles do.
804 =item B<< $metarole->does_role($role) >>
806 Given a role I<name> or L<Moose::Meta::Role> object, returns true if this role
809 =item B<< $metarole->add_role($role) >>
811 Given a L<Moose::Meta::Role> object, this adds the role to the list of
812 roles that the role does.
814 =item B<< $metarole->get_excluded_roles_list >>
816 Returns a list of role names which this role excludes.
818 =item B<< $metarole->excludes_role($role_name) >>
820 Given a role I<name>, returns true if this role excludes the named
823 =item B<< $metarole->add_excluded_roles(@role_names) >>
825 Given one or more role names, adds those roles to the list of excluded
832 The methods for dealing with a role's methods are all identical in API
833 and behavior to the same methods in L<Class::MOP::Class>.
837 =item B<< $metarole->method_metaclass >>
839 Returns the method metaclass name for the role. This defaults to
840 L<Moose::Meta::Role::Method>.
842 =item B<< $metarole->get_method($name) >>
844 =item B<< $metarole->has_method($name) >>
846 =item B<< $metarole->add_method( $name, $body ) >>
848 =item B<< $metarole->get_method_list >>
850 =item B<< $metarole->find_method_by_name($name) >>
852 These methods are all identical to the methods of the same name in
853 L<Class::MOP::Package>
859 As with methods, the methods for dealing with a role's attribute are
860 all identical in API and behavior to the same methods in
861 L<Class::MOP::Class>.
863 However, attributes stored in this class are I<not> stored as
864 objects. Rather, the attribute definition is stored as a hash
865 reference. When a role is composed into a class, this hash reference
866 is passed directly to the metaclass's C<add_attribute> method.
868 This is quite likely to change in the future.
872 =item B<< $metarole->get_attribute($attribute_name) >>
874 =item B<< $metarole->has_attribute($attribute_name) >>
876 =item B<< $metarole->get_attribute_list >>

884 =head2 Required methods
888 =item B<< $metarole->get_required_method_list >>
890 Returns the list of methods required by the role.
892 =item B<< $metarole->requires_method($name) >>
894 Returns true if the role requires the named method.
896 =item B<< $metarole->add_required_methods(@names) >>
898 Adds the named methods to the role's list of required methods.
900 =item B<< $metarole->remove_required_methods(@names) >>
902 Removes the named methods from the role's list of required methods.
904 =item B<< $metarole->add_conflicting_method(%params) >>
906 Instantiate the parameters as a L<Moose::Meta::Role::Method::Conflicting>
907 object, then add it to the required method list.
911 =head2 Method modifiers
913 These methods act like their counterparts in L<Class::MOP::Class> and
914 L<Moose::Meta::Class>.
916 However, method modifiers are simply stored internally, and are not
917 applied until the role itself is applied to a class.
921 =item B<< $metarole->add_after_method_modifier($method_name, $method) >>
923 =item B<< $metarole->add_around_method_modifier($method_name, $method) >>
925 =item B<< $metarole->add_before_method_modifier($method_name, $method) >>
927 =item B<< $metarole->add_override_method_modifier($method_name, $method) >>
929 These methods all add an appropriate modifier to the internal list of
932 =item B<< $metarole->has_after_method_modifiers >>
934 =item B<< $metarole->has_around_method_modifiers >>
936 =item B<< $metarole->has_before_method_modifiers >>
938 =item B<< $metarole->has_override_method_modifier >>
940 Return true if the role has any modifiers of the given type.
942 =item B<< $metarole->get_after_method_modifiers($method_name) >>
944 =item B<< $metarole->get_around_method_modifiers($method_name) >>
946 =item B<< $metarole->get_before_method_modifiers($method_name) >>
948 Given a method name, returns a list of the appropriate modifiers for
951 =item B<< $metarole->get_override_method_modifier($method_name) >>
953 Given a method name, returns the override method modifier for that
954 method, if it has one.
962 =item B<< Moose::Meta::Role->meta >>
964 This will return a L<Class::MOP::Class> instance for this class.
