| 734 | # ABSTRACT: The Moose Role metaclass | ||||
| 735 | |||||
| - - | |||||
| 738 | =pod | ||||
| 739 | |||||
| 740 | =head1 NAME | ||||
| 741 | |||||
| 742 | Moose::Meta::Role - The Moose Role metaclass | ||||
| 743 | |||||
| 744 | =head1 VERSION | ||||
| 745 | |||||
| 746 | version 2.0602 | ||||
| 747 | |||||
| 748 | =head1 DESCRIPTION | ||||
| 749 | |||||
| 750 | This class is a subclass of L<Class::MOP::Module> that provides | ||||
| 751 | additional Moose-specific functionality. | ||||
| 752 | |||||
| 753 | Its API looks a lot like L<Moose::Meta::Class>, but internally it | ||||
| 754 | implements many things differently. This may change in the future. | ||||
| 755 | |||||
| 756 | =head1 INHERITANCE | ||||
| 757 | |||||
| 758 | C<Moose::Meta::Role> is a subclass of L<Class::MOP::Module>. | ||||
| 759 | |||||
| 760 | =head1 METHODS | ||||
| 761 | |||||
| 762 | =head2 Construction | ||||
| 763 | |||||
| 764 | =over 4 | ||||
| 765 | |||||
| 766 | =item B<< Moose::Meta::Role->initialize($role_name) >> | ||||
| 767 | |||||
| 768 | This method creates a new role object with the provided name. | ||||
| 769 | |||||
| 770 | =item B<< Moose::Meta::Role->combine( [ $role => { ... } ], [ $role ], ... ) >> | ||||
| 771 | |||||
| 772 | This method accepts a list of array references. Each array reference | ||||
| 773 | should contain a role name or L<Moose::Meta::Role> object as its first element. The second element is | ||||
| 774 | an optional hash reference. The hash reference can contain C<-excludes> | ||||
| 775 | and C<-alias> keys to control how methods are composed from the role. | ||||
| 776 | |||||
| 777 | The return value is a new L<Moose::Meta::Role::Composite> that | ||||
| 778 | represents the combined roles. | ||||
| 779 | |||||
| 780 | =item B<< $metarole->composition_class_roles >> | ||||
| 781 | |||||
| 782 | When combining multiple roles using C<combine>, this method is used to obtain a | ||||
| 783 | list of role names to be applied to the L<Moose::Meta::Role::Composite> | ||||
| 784 | instance returned by C<combine>. The default implementation returns an empty | ||||
| 785 | list. Extensions that need to hook into role combination may wrap this method | ||||
| 786 | to return additional role names. | ||||
| 787 | |||||
| 788 | =item B<< Moose::Meta::Role->create($name, %options) >> | ||||
| 789 | |||||
| 790 | This method is identical to the L<Moose::Meta::Class> C<create> | ||||
| 791 | method. | ||||
| 792 | |||||
| 793 | =item B<< Moose::Meta::Role->create_anon_role >> | ||||
| 794 | |||||
| 795 | This method is identical to the L<Moose::Meta::Class> | ||||
| 796 | C<create_anon_class> method. | ||||
| 797 | |||||
| 798 | =item B<< $metarole->is_anon_role >> | ||||
| 799 | |||||
| 800 | Returns true if the role is an anonymous role. | ||||
| 801 | |||||
| 802 | =item B<< $metarole->consumers >> | ||||
| 803 | |||||
| 804 | Returns a list of names of classes and roles which consume this role. | ||||
| 805 | |||||
| 806 | =back | ||||
| 807 | |||||
| 808 | =head2 Role application | ||||
| 809 | |||||
| 810 | =over 4 | ||||
| 811 | |||||
| 812 | =item B<< $metarole->apply( $thing, @options ) >> | ||||
| 813 | |||||
| 814 | This method applies a role to the given C<$thing>. That can be another | ||||
| 815 | L<Moose::Meta::Role>, object, a L<Moose::Meta::Class> object, or a | ||||
| 816 | (non-meta) object instance. | ||||
| 817 | |||||
| 818 | The options are passed directly to the constructor for the appropriate | ||||
| 819 | L<Moose::Meta::Role::Application> subclass. | ||||
| 820 | |||||
| 821 | Note that this will apply the role even if the C<$thing> in question already | ||||
| 822 | C<does> this role. L<Moose::Util/does_role> is a convenient wrapper for | ||||
| 823 | finding out if role application is necessary. | ||||
| 824 | |||||
| 825 | =back | ||||
| 826 | |||||
| 827 | =head2 Roles and other roles | ||||
| 828 | |||||
| 829 | =over 4 | ||||
| 830 | |||||
| 831 | =item B<< $metarole->get_roles >> | ||||
| 832 | |||||
| 833 | This returns an array reference of roles which this role does. This | ||||
| 834 | list may include duplicates. | ||||
| 835 | |||||
| 836 | =item B<< $metarole->calculate_all_roles >> | ||||
| 837 | |||||
| 838 | This returns a I<unique> list of all roles that this role does, and | ||||
| 839 | all the roles that its roles do. | ||||
| 840 | |||||
| 841 | =item B<< $metarole->does_role($role) >> | ||||
| 842 | |||||
| 843 | Given a role I<name> or L<Moose::Meta::Role> object, returns true if this role | ||||
| 844 | does the given role. | ||||
| 845 | |||||
| 846 | =item B<< $metarole->add_role($role) >> | ||||
| 847 | |||||
| 848 | Given a L<Moose::Meta::Role> object, this adds the role to the list of | ||||
| 849 | roles that the role does. | ||||
| 850 | |||||
| 851 | =item B<< $metarole->get_excluded_roles_list >> | ||||
| 852 | |||||
| 853 | Returns a list of role names which this role excludes. | ||||
| 854 | |||||
| 855 | =item B<< $metarole->excludes_role($role_name) >> | ||||
| 856 | |||||
| 857 | Given a role I<name>, returns true if this role excludes the named | ||||
| 858 | role. | ||||
| 859 | |||||
| 860 | =item B<< $metarole->add_excluded_roles(@role_names) >> | ||||
| 861 | |||||
| 862 | Given one or more role names, adds those roles to the list of excluded | ||||
| 863 | roles. | ||||
| 864 | |||||
| 865 | =back | ||||
| 866 | |||||
| 867 | =head2 Methods | ||||
| 868 | |||||
| 869 | The methods for dealing with a role's methods are all identical in API | ||||
| 870 | and behavior to the same methods in L<Class::MOP::Class>. | ||||
| 871 | |||||
| 872 | =over 4 | ||||
| 873 | |||||
| 874 | =item B<< $metarole->method_metaclass >> | ||||
| 875 | |||||
| 876 | Returns the method metaclass name for the role. This defaults to | ||||
| 877 | L<Moose::Meta::Role::Method>. | ||||
| 878 | |||||
| 879 | =item B<< $metarole->get_method($name) >> | ||||
| 880 | |||||
| 881 | =item B<< $metarole->has_method($name) >> | ||||
| 882 | |||||
| 883 | =item B<< $metarole->add_method( $name, $body ) >> | ||||
| 884 | |||||
| 885 | =item B<< $metarole->get_method_list >> | ||||
| 886 | |||||
| 887 | =item B<< $metarole->find_method_by_name($name) >> | ||||
| 888 | |||||
| 889 | These methods are all identical to the methods of the same name in | ||||
| 890 | L<Class::MOP::Package> | ||||
| 891 | |||||
| 892 | =back | ||||
| 893 | |||||
| 894 | =head2 Attributes | ||||
| 895 | |||||
| 896 | As with methods, the methods for dealing with a role's attribute are | ||||
| 897 | all identical in API and behavior to the same methods in | ||||
| 898 | L<Class::MOP::Class>. | ||||
| 899 | |||||
| 900 | However, attributes stored in this class are I<not> stored as | ||||
| 901 | objects. Rather, the attribute definition is stored as a hash | ||||
| 902 | reference. When a role is composed into a class, this hash reference | ||||
| 903 | is passed directly to the metaclass's C<add_attribute> method. | ||||
| 904 | |||||
| 905 | This is quite likely to change in the future. | ||||
| 906 | |||||
| 907 | =over 4 | ||||
| 908 | |||||
| 909 | =item B<< $metarole->get_attribute($attribute_name) >> | ||||
| 910 | |||||
| 911 | =item B<< $metarole->has_attribute($attribute_name) >> | ||||

| 919 | =back | ||||
| 920 | |||||
| 921 | =head2 Overload introspection and creation | ||||
| 922 | |||||
| 923 | The methods for dealing with a role's overloads are all identical in API | ||||
| 924 | and behavior to the same methods in L<Class::MOP::Class>. Note that these are | ||||
| 925 | not particularly useful (yet), because overloads do not participate in role | ||||
| 926 | composition. | ||||
| 927 | |||||
| 928 | =over 4 | ||||
