42# NOTE:
43# since roles are lazy, we hold all the attributes
44# of the individual role in 'statis' until which
45# time when it is applied to a class. This means
46# keeping a lot of things in hash maps, so we are
47# using a little of that meta-programmin' magic
48# here an saving lots of extra typin. And since
49# many of these attributes above require similar
50# functionality to support them, so we again use
51# the wonders of meta-programmin' to deliver a
52# very compact solution to this normally verbose

680=head1 NAME
681
682Moose::Meta::Role - The Moose Role metaclass
683
684=head1 DESCRIPTION
685
686This class is a subclass of L<Class::MOP::Module> that provides
687additional Moose-specific functionality.
688
689It's API looks a lot like L<Moose::Meta::Class>, but internally it
690implements many things differently. This may change in the future.
691
692=head1 INHERITANCE
693
694C<Moose::Meta::Role> is a subclass of L<Class::MOP::Module>.
695
696=head1 METHODS
697
698=head2 Construction
699
700=over 4
701
702=item B<< Moose::Meta::Role->initialize($role_name) >>
703
704This method creates a new role object with the provided name.
705
706=item B<< Moose::Meta::Role->combine( [ $role => { ... } ], [ $role ], ... ) >>
707
708This method accepts a list of array references. Each array reference
709should contain a role name or L<Moose::Meta::Role> object as its first element. The second element is
710an optional hash reference. The hash reference can contain C<-excludes>
711and C<-alias> keys to control how methods are composed from the role.
712
713The return value is a new L<Moose::Meta::Role::Composite> that
714represents the combined roles.
715
716=item B<< $metarole->composition_class_roles >>
717
718When combining multiple roles using C<combine>, this method is used to obtain a
719list of role names to be applied to the L<Moose::Meta::Role::Composite>
720instance returned by C<combine>. The default implementation returns an empty
721list. Extensions that need to hook into role combination may wrap this method
722to return additional role names.
723
724=item B<< Moose::Meta::Role->create($name, %options) >>
725
726This method is identical to the L<Moose::Meta::Class> C<create>
727method.
728
729=item B<< Moose::Meta::Role->create_anon_role >>
730
731This method is identical to the L<Moose::Meta::Class>
732C<create_anon_class> method.
733
734=item B<< $metarole->is_anon_role >>
735
736Returns true if the role is an anonymous role.
737
738=back
739
740=head2 Role application
741
742=over 4
743
744=item B<< $metarole->apply( $thing, @options ) >>
745
746This method applies a role to the given C<$thing>. That can be another
747L<Moose::Meta::Role>, object, a L<Moose::Meta::Class> object, or a
748(non-meta) object instance.
749
750The options are passed directly to the constructor for the appropriate
751L<Moose::Meta::Role::Application> subclass.
752
753Note that this will apply the role even if the C<$thing> in question already
754C<does> this role. L<Moose::Util/does_role> is a convenient wrapper for
755finding out if role application is necessary.
756
757=back
758
759=head2 Roles and other roles
760
761=over 4
762
763=item B<< $metarole->get_roles >>
764
765This returns an array reference of roles which this role does. This
766list may include duplicates.
767
768=item B<< $metarole->calculate_all_roles >>
769
770This returns a I<unique> list of all roles that this role does, and
771all the roles that its roles do.
772
773=item B<< $metarole->does_role($role) >>
774
775Given a role I<name> or L<Moose::Meta::Role> object, returns true if this role
776does the given role.
777
778=item B<< $metarole->add_role($role) >>
779
780Given a L<Moose::Meta::Role> object, this adds the role to the list of
781roles that the role does.
782
783=item B<< $metarole->get_excluded_roles_list >>
784
785Returns a list of role names which this role excludes.
786
787=item B<< $metarole->excludes_role($role_name) >>
788
789Given a role I<name>, returns true if this role excludes the named
790role.
791
792=item B<< $metarole->add_excluded_roles(@role_names) >>
793
794Given one or more role names, adds those roles to the list of excluded
795roles.
796
797=back
798
799=head2 Methods
800
801The methods for dealing with a role's methods are all identical in API
802and behavior to the same methods in L<Class::MOP::Class>.
803
804=over 4
805
806=item B<< $metarole->method_metaclass >>
807
808Returns the method metaclass name for the role. This defaults to
809L<Moose::Meta::Role::Method>.
810
811=item B<< $metarole->get_method($name) >>
812
813=item B<< $metarole->has_method($name) >>
814
815=item B<< $metarole->add_method( $name, $body ) >>
816
817=item B<< $metarole->get_method_list >>
818
819=item B<< $metarole->find_method_by_name($name) >>
820
821These methods are all identical to the methods of the same name in
822L<Class::MOP::Package>
823
824=back
825
826=head2 Attributes
827
828As with methods, the methods for dealing with a role's attribute are
829all identical in API and behavior to the same methods in
830L<Class::MOP::Class>.
831
832However, attributes stored in this class are I<not> stored as
833objects. Rather, the attribute definition is stored as a hash
834reference. When a role is composed into a class, this hash reference
835is passed directly to the metaclass's C<add_attribute> method.
836
837This is quite likely to change in the future.
838
839=over 4
840
841=item B<< $metarole->get_attribute($attribute_name) >>
842
843=item B<< $metarole->has_attribute($attribute_name) >>
844
845=item B<< $metarole->get_attribute_list >>
846
847=item B<< $metarole->add_attribute($name, %options) >>
848
849=item B<< $metarole->remove_attribute($attribute_name) >>
850
851=back
852
853=head2 Required methods
854
855=over 4
856
857=item B<< $metarole->get_required_method_list >>
858
859Returns the list of methods required by the role.
860
861=item B<< $metarole->requires_method($name) >>
862
863Returns true if the role requires the named method.
864
865=item B<< $metarole->add_required_methods(@names) >>
866
867Adds the named methods to the role's list of required methods.
868
869=item B<< $metarole->remove_required_methods(@names) >>
870
871Removes the named methods from the role's list of required methods.
872
873=item B<< $metarole->add_conflicting_method(%params) >>
874
875Instantiate the parameters as a L<Moose::Meta::Role::Method::Conflicting>
876object, then add it to the required method list.
877
878=back
879
880=head2 Method modifiers
881
882These methods act like their counterparts in L<Class::MOP::Class> and
883L<Moose::Meta::Class>.
884
885However, method modifiers are simply stored internally, and are not
886applied until the role itself is applied to a class.
887
888=over 4
889
890=item B<< $metarole->add_after_method_modifier($method_name, $method) >>
891
892=item B<< $metarole->add_around_method_modifier($method_name, $method) >>
893
894=item B<< $metarole->add_before_method_modifier($method_name, $method) >>
895
896=item B<< $metarole->add_override_method_modifier($method_name, $method) >>
897
898These methods all add an appropriate modifier to the internal list of
899modifiers.
900
901=item B<< $metarole->has_after_method_modifiers >>
902
903=item B<< $metarole->has_around_method_modifiers >>
904
905=item B<< $metarole->has_before_method_modifiers >>
906
907=item B<< $metarole->has_override_method_modifier >>
908
909Return true if the role has any modifiers of the given type.
910
911=item B<< $metarole->get_after_method_modifiers($method_name) >>
912
913=item B<< $metarole->get_around_method_modifiers($method_name) >>
914
915=item B<< $metarole->get_before_method_modifiers($method_name) >>
916
917Given a method name, returns a list of the appropriate modifiers for
918that method.
919
920=item B<< $metarole->get_override_method_modifier($method_name) >>
921
922Given a method name, returns the override method modifier for that
923method, if it has one.
924
925=back
926
927=head2 Introspection
928
929=over 4
930
931=item B<< Moose::Meta::Role->meta >>
932
933This will return a L<Class::MOP::Class> instance for this class.
