736 | =head1 NAME | |||
737 | ||||
738 | Class::MOP - A Meta Object Protocol for Perl 5 | |||
739 | ||||
740 | =head1 DESCRIPTION | |||
741 | ||||
742 | This module is a fully functioning meta object protocol for the | |||
743 | Perl 5 object system. It makes no attempt to change the behavior or | |||
744 | characteristics of the Perl 5 object system, only to create a | |||
745 | protocol for its manipulation and introspection. | |||
746 | ||||
747 | That said, it does attempt to create the tools for building a rich set | |||
748 | of extensions to the Perl 5 object system. Every attempt has been made | |||
749 | to abide by the spirit of the Perl 5 object system that we all know | |||
750 | and love. | |||
751 | ||||
752 | This documentation is sparse on conceptual details. We suggest looking | |||
753 | at the items listed in the L<SEE ALSO> section for more | |||
754 | information. In particular the book "The Art of the Meta Object | |||
755 | Protocol" was very influential in the development of this system. | |||
756 | ||||
757 | =head2 What is a Meta Object Protocol? | |||
758 | ||||
759 | A meta object protocol is an API to an object system. | |||
760 | ||||
761 | To be more specific, it abstracts the components of an object system | |||
762 | (classes, object, methods, object attributes, etc.). These | |||
763 | abstractions can then be used to inspect and manipulate the object | |||
764 | system which they describe. | |||
765 | ||||
766 | It can be said that there are two MOPs for any object system; the | |||
767 | implicit MOP and the explicit MOP. The implicit MOP handles things | |||
768 | like method dispatch or inheritance, which happen automatically as | |||
769 | part of how the object system works. The explicit MOP typically | |||
770 | handles the introspection/reflection features of the object system. | |||
771 | ||||
772 | All object systems have implicit MOPs. Without one, they would not | |||
773 | work. Explicit MOPs are much less common, and depending on the | |||
774 | language can vary from restrictive (Reflection in Java or C#) to wide | |||
775 | open (CLOS is a perfect example). | |||
776 | ||||
777 | =head2 Yet Another Class Builder! Why? | |||
778 | ||||
779 | This is B<not> a class builder so much as a I<class builder | |||
780 | B<builder>>. The intent is that an end user will not use this module | |||
781 | directly, but instead this module is used by module authors to build | |||
782 | extensions and features onto the Perl 5 object system. | |||
783 | ||||
784 | This system is used by L<Moose>, which supplies a powerful class | |||
785 | builder system built entirely on top of C<Class::MOP>. | |||
786 | ||||
787 | =head2 Who is this module for? | |||
788 | ||||
789 | This module is for anyone who has ever created or wanted to create a | |||
790 | module for the Class:: namespace. The tools which this module provides | |||
791 | make doing complex Perl 5 wizardry simpler, by removing such barriers | |||
792 | as the need to hack symbol tables, or understand the fine details of | |||
793 | method dispatch. | |||
794 | ||||
795 | =head2 What changes do I have to make to use this module? | |||
796 | ||||
797 | This module was designed to be as unintrusive as possible. Many of its | |||
798 | features are accessible without B<any> change to your existing | |||
799 | code. It is meant to be a compliment to your existing code and not an | |||
800 | intrusion on your code base. Unlike many other B<Class::> modules, | |||
801 | this module B<does not> require you subclass it, or even that you | |||
802 | C<use> it in within your module's package. | |||
803 | ||||
804 | The only features which requires additions to your code are the | |||
805 | attribute handling and instance construction features, and these are | |||
806 | both completely optional features. The only reason for this is because | |||
807 | Perl 5's object system does not actually have these features built | |||
808 | in. More information about this feature can be found below. | |||
809 | ||||
810 | =head2 About Performance | |||
811 | ||||
812 | It is a common misconception that explicit MOPs are a performance hit. | |||
813 | This is not a universal truth, it is a side-effect of some specific | |||
814 | implementations. For instance, using Java reflection is slow because | |||
815 | the JVM cannot take advantage of any compiler optimizations, and the | |||
816 | JVM has to deal with much more runtime type information as well. | |||
817 | ||||
818 | Reflection in C# is marginally better as it was designed into the | |||
819 | language and runtime (the CLR). In contrast, CLOS (the Common Lisp | |||
820 | Object System) was built to support an explicit MOP, and so | |||
821 | performance is tuned for it. | |||
822 | ||||
823 | This library in particular does its absolute best to avoid putting | |||
824 | B<any> drain at all upon your code's performance. In fact, by itself | |||
825 | it does nothing to affect your existing code. So you only pay for what | |||
826 | you actually use. | |||
827 | ||||
828 | =head2 About Metaclass compatibility | |||
829 | ||||
830 | This module makes sure that all metaclasses created are both upwards | |||
831 | and downwards compatible. The topic of metaclass compatibility is | |||
832 | highly esoteric and is something only encountered when doing deep and | |||
833 | involved metaclass hacking. There are two basic kinds of metaclass | |||
834 | incompatibility; upwards and downwards. | |||
835 | ||||
836 | Upwards metaclass compatibility means that the metaclass of a | |||
837 | given class is either the same as (or a subclass of) all of the | |||
838 | class's ancestors. | |||
839 | ||||
840 | Downward metaclass compatibility means that the metaclasses of a | |||
841 | given class's ancestors are all either the same as (or a subclass | |||
842 | of) that metaclass. | |||
843 | ||||
844 | Here is a diagram showing a set of two classes (C<A> and C<B>) and | |||
845 | two metaclasses (C<Meta::A> and C<Meta::B>) which have correct | |||
846 | metaclass compatibility both upwards and downwards. | |||
847 | ||||
848 | +---------+ +---------+ | |||
849 | | Meta::A |<----| Meta::B | <....... (instance of ) | |||
850 | +---------+ +---------+ <------- (inherits from) | |||
851 | ^ ^ | |||
852 | : : | |||
853 | +---------+ +---------+ | |||
854 | | A |<----| B | | |||
855 | +---------+ +---------+ | |||
856 | ||||
857 | In actuality, I<all> of a class's metaclasses must be compatible, | |||
858 | not just the class metaclass. That includes the instance, attribute, | |||
859 | and method metaclasses, as well as the constructor and destructor | |||
860 | classes. | |||
861 | ||||
862 | C<Class::MOP> will attempt to fix some simple types of | |||
863 | incompatibilities. If all the metaclasses for the parent class are | |||
864 | I<subclasses> of the child's metaclasses then we can simply replace | |||
865 | the child's metaclasses with the parent's. In addition, if the child | |||
866 | is missing a metaclass that the parent has, we can also just make the | |||
867 | child use the parent's metaclass. | |||
868 | ||||
869 | As I said this is a highly esoteric topic and one you will only run | |||
870 | into if you do a lot of subclassing of L<Class::MOP::Class>. If you | |||
871 | are interested in why this is an issue see the paper I<Uniform and | |||
872 | safe metaclass composition> linked to in the L<SEE ALSO> section of | |||
873 | this document. | |||
874 | ||||
875 | =head2 Using custom metaclasses | |||
876 | ||||
877 | Always use the L<metaclass> pragma when using a custom metaclass, this | |||
878 | will ensure the proper initialization order and not accidentally | |||
879 | create an incorrect type of metaclass for you. This is a very rare | |||
880 | problem, and one which can only occur if you are doing deep metaclass | |||
881 | programming. So in other words, don't worry about it. | |||
882 | ||||
883 | Note that if you're using L<Moose> we encourage you to I<not> use | |||
884 | L<metaclass> pragma, and instead use L<Moose::Util::MetaRole> to apply | |||
885 | roles to a class's metaclasses. This topic is covered at length in | |||
886 | various L<Moose::Cookbook> recipes. | |||
887 | ||||
888 | =head1 PROTOCOLS | |||
889 | ||||
890 | The meta-object protocol is divided into 4 main sub-protocols: | |||
891 | ||||
892 | =head2 The Class protocol | |||
893 | ||||
894 | This provides a means of manipulating and introspecting a Perl 5 | |||
895 | class. It handles symbol table hacking for you, and provides a rich | |||
896 | set of methods that go beyond simple package introspection. | |||

900 | =head2 The Attribute protocol | |||
901 | ||||
902 | This provides a consistent representation for an attribute of a Perl 5 | |||
903 | class. Since there are so many ways to create and handle attributes in | |||
904 | Perl 5 OO, the Attribute protocol provide as much of a unified | |||
905 | approach as possible. Of course, you are always free to extend this | |||
906 | protocol by subclassing the appropriate classes. | |||
907 | ||||
908 | See L<Class::MOP::Attribute> for more details. | |||
909 | ||||
910 | =head2 The Method protocol | |||
911 | ||||
912 | This provides a means of manipulating and introspecting methods in the | |||
913 | Perl 5 object system. As with attributes, there are many ways to | |||
914 | approach this topic, so we try to keep it pretty basic, while still | |||
915 | making it possible to extend the system in many ways. | |||
916 | ||||
917 | See L<Class::MOP::Method> for more details. | |||
918 | ||||
919 | =head2 The Instance protocol | |||
920 | ||||
921 | This provides a layer of abstraction for creating object instances. | |||
922 | Since the other layers use this protocol, it is relatively easy to | |||
923 | change the type of your instances from the default hash reference to | |||
924 | some other type of reference. Several examples are provided in the | |||
925 | F<examples/> directory included in this distribution. | |||
926 | ||||
927 | See L<Class::MOP::Instance> for more details. | |||
928 | ||||
929 | =head1 FUNCTIONS | |||
930 | ||||
931 | Note that this module does not export any constants or functions. | |||
932 | ||||
933 | =head2 Constants | |||
934 | ||||
935 | =over 4 | |||
936 | ||||
937 | =item I<Class::MOP::IS_RUNNING_ON_5_10> | |||
938 | ||||
939 | We set this constant depending on what version perl we are on, this | |||
940 | allows us to take advantage of new 5.10 features and stay backwards | |||
941 | compatible. | |||
942 | ||||
943 | =back | |||
944 | ||||
945 | =head2 Utility functions | |||
946 | ||||
947 | Note that these are all called as B<functions, not methods>. | |||
948 | ||||
949 | =over 4 | |||
950 | ||||
951 | =item B<Class::MOP::load_class($class_name, \%options?)> | |||
952 | ||||
953 | This will load the specified C<$class_name>, if it is not already | |||
954 | loaded (as reported by C<is_class_loaded>). This function can be used | |||
955 | in place of tricks like C<eval "use $module"> or using C<require> | |||
956 | unconditionally. | |||
957 | ||||
958 | If the module cannot be loaded, an exception is thrown. | |||
959 | ||||
960 | You can pass a hash reference with options as second argument. The | |||
961 | only option currently recognised is C<-version>, which will ensure | |||
962 | that the loaded class has at least the required version. | |||
963 | ||||
964 | See also L</Class Loading Options>. | |||
965 | ||||
966 | For historical reasons, this function explicitly returns a true value. | |||
967 | ||||
968 | =item B<Class::MOP::is_class_loaded($class_name, \%options?)> | |||
969 | ||||
970 | Returns a boolean indicating whether or not C<$class_name> has been | |||
971 | loaded. | |||
972 | ||||
973 | This does a basic check of the symbol table to try and determine as | |||
974 | best it can if the C<$class_name> is loaded, it is probably correct | |||
975 | about 99% of the time, but it can be fooled into reporting false | |||
976 | positives. In particular, loading any of the core L<IO> modules will | |||
977 | cause most of the rest of the core L<IO> modules to falsely report | |||
978 | having been loaded, due to the way the base L<IO> module works. | |||
979 | ||||
980 | You can pass a hash reference with options as second argument. The | |||
981 | only option currently recognised is C<-version>, which will ensure | |||
982 | that the loaded class has at least the required version. | |||
983 | ||||
984 | See also L</Class Loading Options>. | |||
985 | ||||
986 | =item B<Class::MOP::get_code_info($code)> | |||
987 | ||||
988 | This function returns two values, the name of the package the C<$code> | |||
989 | is from and the name of the C<$code> itself. This is used by several | |||
990 | elements of the MOP to determine where a given C<$code> reference is | |||
991 | from. | |||
992 | ||||
993 | =item B<Class::MOP::class_of($instance_or_class_name)> | |||
994 | ||||
995 | This will return the metaclass of the given instance or class name. If the | |||
996 | class lacks a metaclass, no metaclass will be initialized, and C<undef> will be | |||
997 | returned. | |||
998 | ||||
999 | =item B<Class::MOP::check_package_cache_flag($pkg)> | |||
1000 | ||||
1001 | B<NOTE: DO NOT USE THIS FUNCTION, IT IS FOR INTERNAL USE ONLY!> | |||
1002 | ||||
1003 | This will return an integer that is managed by L<Class::MOP::Class> to | |||
1004 | determine if a module's symbol table has been altered. | |||
1005 | ||||
1006 | In Perl 5.10 or greater, this flag is package specific. However in | |||
1007 | versions prior to 5.10, this will use the C<PL_sub_generation> | |||
1008 | variable which is not package specific. | |||
1009 | ||||
1010 | =item B<Class::MOP::load_first_existing_class(@class_names)> | |||
1011 | ||||
1012 | =item B<Class::MOP::load_first_existing_class($classA, \%optionsA?, $classB, ...)> | |||
1013 | ||||
1014 | B<NOTE: DO NOT USE THIS FUNCTION, IT IS FOR INTERNAL USE ONLY!> | |||
1015 | ||||
1016 | Given a list of class names, this function will attempt to load each | |||
1017 | one in turn. | |||
1018 | ||||
1019 | If it finds a class it can load, it will return that class' name. If | |||
1020 | none of the classes can be loaded, it will throw an exception. | |||
1021 | ||||
1022 | Additionally, you can pass a hash reference with options after each | |||
1023 | class name. Currently, only C<-version> is recognised and will ensure | |||
1024 | that the loaded class has at least the required version. If the class | |||
1025 | version is not sufficient, an exception will be raised. | |||
1026 | ||||
1027 | See also L</Class Loading Options>. | |||

1031 | =head2 Metaclass cache functions | |||
1032 | ||||
1033 | Class::MOP holds a cache of metaclasses. The following are functions | |||
1034 | (B<not methods>) which can be used to access that cache. It is not | |||
1035 | recommended that you mess with these. Bad things could happen, but if | |||
1036 | you are brave and willing to risk it: go for it! | |||
1037 | ||||
1038 | =over 4 | |||
1039 | ||||
1040 | =item B<Class::MOP::get_all_metaclasses> | |||
1041 | ||||
1042 | This will return a hash of all the metaclass instances that have | |||
1043 | been cached by L<Class::MOP::Class>, keyed by the package name. | |||
1044 | ||||
1045 | =item B<Class::MOP::get_all_metaclass_instances> | |||
1046 | ||||
1047 | This will return a list of all the metaclass instances that have | |||
1048 | been cached by L<Class::MOP::Class>. | |||
1049 | ||||
1050 | =item B<Class::MOP::get_all_metaclass_names> | |||
1051 | ||||
1052 | This will return a list of all the metaclass names that have | |||
1053 | been cached by L<Class::MOP::Class>. | |||
1054 | ||||
1055 | =item B<Class::MOP::get_metaclass_by_name($name)> | |||
1056 | ||||
1057 | This will return a cached L<Class::MOP::Class> instance, or nothing | |||
1058 | if no metaclass exists with that C<$name>. | |||
1059 | ||||
1060 | =item B<Class::MOP::store_metaclass_by_name($name, $meta)> | |||
1061 | ||||
1062 | This will store a metaclass in the cache at the supplied C<$key>. | |||
1063 | ||||
1064 | =item B<Class::MOP::weaken_metaclass($name)> | |||
1065 | ||||
1066 | In rare cases (e.g. anonymous metaclasses) it is desirable to | |||
1067 | store a weakened reference in the metaclass cache. This | |||
1068 | function will weaken the reference to the metaclass stored | |||
1069 | in C<$name>. | |||
1070 | ||||
1071 | =item B<Class::MOP::does_metaclass_exist($name)> | |||
1072 | ||||
1073 | This will return true of there exists a metaclass stored in the | |||
1074 | C<$name> key, and return false otherwise. | |||
1075 | ||||
1076 | =item B<Class::MOP::remove_metaclass_by_name($name)> | |||
1077 | ||||
1078 | This will remove the metaclass stored in the C<$name> key. | |||

1098 | because it is such an esoteric topic. The following books are really | |||

1119 | ||||
1120 | An excellent paper by the people who brought us the original Traits paper. | |||
1121 | This paper is on how Traits can be used to do safe metaclass composition, | |||
1122 | and offers an excellent introduction section which delves into the topic of | |||
1123 | metaclass compatibility. | |||

1126 | ||||
1127 | =item "Safe Metaclass Programming" | |||
1128 | ||||
1129 | This paper seems to precede the above paper, and propose a mix-in based | |||
1130 | approach as opposed to the Traits based approach. Both papers have similar | |||
1131 | information on the metaclass compatibility problem space. | |||

1163 | =head1 SIMILAR MODULES | |||
1164 | ||||
1165 | As I have said above, this module is a class-builder-builder, so it is | |||
1166 | not the same thing as modules like L<Class::Accessor> and | |||
1167 | L<Class::MethodMaker>. That being said there are very few modules on CPAN | |||
1168 | with similar goals to this module. The one I have found which is most | |||
1169 | like this module is L<Class::Meta>, although it's philosophy and the MOP it | |||
1170 | creates are very different from this modules. | |||
1171 | ||||
1172 | =head1 BUGS | |||
1173 | ||||
1174 | All complex software has bugs lurking in it, and this module is no | |||
1175 | exception. | |||

1177 | Please report any bugs to C<bug-class-mop@rt.cpan.org>, or through the | |||
1178 | web interface at L<http://rt.cpan.org>. | |||
