142## Setting up our environment ...
143## ----------------------------------------------------------------------------
144## Class::MOP needs to have a few things in the global perl environment so
145## that it can operate effectively. Those things are done here.

147
148# ... nothing yet actually ;)
149
150## ----------------------------------------------------------------------------
151## Bootstrapping
152## ----------------------------------------------------------------------------
153## The code below here is to bootstrap our MOP with itself. This is also
154## sometimes called "tying the knot". By doing this, we make it much easier
155## to extend the MOP through subclassing and such since now you can use the
156## MOP itself to extend itself.
157##
158## Yes, I know, thats weird and insane, but it's a good thing, trust me :)
159## ----------------------------------------------------------------------------
160
161# We need to add in the meta-attributes here so that
162# any subclass of Class::MOP::* will be able to
163# inherit them using _construct_instance

714=head1 NAME
715
716Class::MOP - A Meta Object Protocol for Perl 5
717
718=head1 DESCRIPTION
719
720This module is a fully functioning meta object protocol for the
721Perl 5 object system. It makes no attempt to change the behavior or
722characteristics of the Perl 5 object system, only to create a
723protocol for its manipulation and introspection.
724
725That said, it does attempt to create the tools for building a rich set
726of extensions to the Perl 5 object system. Every attempt has been made
727to abide by the spirit of the Perl 5 object system that we all know
728and love.
729
730This documentation is sparse on conceptual details. We suggest looking
731at the items listed in the L<SEE ALSO> section for more
732information. In particular the book "The Art of the Meta Object
733Protocol" was very influential in the development of this system.
734
735=head2 What is a Meta Object Protocol?
736
737A meta object protocol is an API to an object system.
738
739To be more specific, it abstracts the components of an object system
740(classes, object, methods, object attributes, etc.). These
741abstractions can then be used to inspect and manipulate the object
742system which they describe.
743
744It can be said that there are two MOPs for any object system; the
745implicit MOP and the explicit MOP. The implicit MOP handles things
746like method dispatch or inheritance, which happen automatically as
747part of how the object system works. The explicit MOP typically
748handles the introspection/reflection features of the object system.
749
750All object systems have implicit MOPs. Without one, they would not
751work. Explicit MOPs are much less common, and depending on the
752language can vary from restrictive (Reflection in Java or C#) to wide
753open (CLOS is a perfect example).
754
755=head2 Yet Another Class Builder! Why?
756
757This is B<not> a class builder so much as a I<class builder
758B<builder>>. The intent is that an end user will not use this module
759directly, but instead this module is used by module authors to build
760extensions and features onto the Perl 5 object system.
761
762This system is used by L<Moose>, which supplies a powerful class
763builder system built entirely on top of C<Class::MOP>.
764
765=head2 Who is this module for?
766
767This module is for anyone who has ever created or wanted to create a
768module for the Class:: namespace. The tools which this module provides
769make doing complex Perl 5 wizardry simpler, by removing such barriers
770as the need to hack symbol tables, or understand the fine details of
771method dispatch.
772
773=head2 What changes do I have to make to use this module?
774
775This module was designed to be as unintrusive as possible. Many of its
776features are accessible without B<any> change to your existing
777code. It is meant to be a compliment to your existing code and not an
778intrusion on your code base. Unlike many other B<Class::> modules,
779this module B<does not> require you subclass it, or even that you
780C<use> it in within your module's package.
781
782The only features which requires additions to your code are the
783attribute handling and instance construction features, and these are
784both completely optional features. The only reason for this is because
785Perl 5's object system does not actually have these features built
786in. More information about this feature can be found below.
787
788=head2 About Performance
789
790It is a common misconception that explicit MOPs are a performance hit.
791This is not a universal truth, it is a side-effect of some specific
792implementations. For instance, using Java reflection is slow because
793the JVM cannot take advantage of any compiler optimizations, and the
794JVM has to deal with much more runtime type information as well.
795
796Reflection in C# is marginally better as it was designed into the
797language and runtime (the CLR). In contrast, CLOS (the Common Lisp
798Object System) was built to support an explicit MOP, and so
799performance is tuned for it.
800
801This library in particular does its absolute best to avoid putting
802B<any> drain at all upon your code's performance. In fact, by itself
803it does nothing to affect your existing code. So you only pay for what
804you actually use.
805
806=head2 About Metaclass compatibility
807
808This module makes sure that all metaclasses created are both upwards
809and downwards compatible. The topic of metaclass compatibility is
810highly esoteric and is something only encountered when doing deep and
811involved metaclass hacking. There are two basic kinds of metaclass
812incompatibility; upwards and downwards.
813
814Upwards metaclass compatibility means that the metaclass of a
815given class is either the same as (or a subclass of) all of the
816class's ancestors.
817
818Downward metaclass compatibility means that the metaclasses of a
819given class's ancestors are all either the same as (or a subclass
820of) that metaclass.
821
822Here is a diagram showing a set of two classes (C<A> and C<B>) and
823two metaclasses (C<Meta::A> and C<Meta::B>) which have correct
824metaclass compatibility both upwards and downwards.
825
826 +---------+ +---------+
827 | Meta::A |<----| Meta::B | <....... (instance of )
828 +---------+ +---------+ <------- (inherits from)
829 ^ ^
830 : :
831 +---------+ +---------+
832 | A |<----| B |
833 +---------+ +---------+
834
835As I said this is a highly esoteric topic and one you will only run
836into if you do a lot of subclassing of L<Class::MOP::Class>. If you
837are interested in why this is an issue see the paper I<Uniform and
838safe metaclass composition> linked to in the L<SEE ALSO> section of
839this document.
840
841=head2 Using custom metaclasses
842
843Always use the L<metaclass> pragma when using a custom metaclass, this
844will ensure the proper initialization order and not accidentally
845create an incorrect type of metaclass for you. This is a very rare
846problem, and one which can only occur if you are doing deep metaclass
847programming. So in other words, don't worry about it.
848
849Note that if you're using L<Moose> we encourage you to I<not> use
850L<metaclass> pragma, and instead use L<Moose::Util::MetaRole> to apply
851roles to a class's metaclasses. This topic is covered at length in
852various L<Moose::Cookbook> recipes.
853
854=head1 PROTOCOLS
855
856The meta-object protocol is divided into 4 main sub-protocols:
857
858=head2 The Class protocol
859
860This provides a means of manipulating and introspecting a Perl 5
861class. It handles symbol table hacking for you, and provides a rich
862set of methods that go beyond simple package introspection.
863
864See L<Class::MOP::Class> for more details.
865
866=head2 The Attribute protocol
867
868This provides a consistent representation for an attribute of a Perl 5
869class. Since there are so many ways to create and handle attributes in
870Perl 5 OO, the Attribute protocol provide as much of a unified
871approach as possible. Of course, you are always free to extend this
872protocol by subclassing the appropriate classes.
873
874See L<Class::MOP::Attribute> for more details.
875
876=head2 The Method protocol
877
878This provides a means of manipulating and introspecting methods in the
879Perl 5 object system. As with attributes, there are many ways to
880approach this topic, so we try to keep it pretty basic, while still
881making it possible to extend the system in many ways.
882
883See L<Class::MOP::Method> for more details.
884
885=head2 The Instance protocol
886
887This provides a layer of abstraction for creating object instances.
888Since the other layers use this protocol, it is relatively easy to
889change the type of your instances from the default hash reference to
890some other type of reference. Several examples are provided in the
891F<examples/> directory included in this distribution.
892
893See L<Class::MOP::Instance> for more details.
894
895=head1 FUNCTIONS
896
897Note that this module does not export any constants or functions.
898
899=head2 Constants
900
901=over 4
902
903=item I<Class::MOP::IS_RUNNING_ON_5_10>
904
905We set this constant depending on what version perl we are on, this
906allows us to take advantage of new 5.10 features and stay backwards
907compatible.
908
909=back
910
911=head2 Utility functions
912
913Note that these are all called as B<functions, not methods>.
914
915=over 4
916
917=item B<Class::MOP::load_class($class_name)>
918
919This will load the specified C<$class_name>, if it is not already
920loaded (as reported by C<is_class_loaded>). This function can be used
921in place of tricks like C<eval "use $module"> or using C<require>
922unconditionally.
923
924If the module cannot be loaded, an exception is thrown.
925
926For historical reasons, this function explicitly returns a true value.
927
928=item B<Class::MOP::is_class_loaded($class_name)>
929
930Returns a boolean indicating whether or not C<$class_name> has been
931loaded.
932
933This does a basic check of the symbol table to try and determine as
934best it can if the C<$class_name> is loaded, it is probably correct
935about 99% of the time, but it can be fooled into reporting false
936positives. In particular, loading any of the core L<IO> modules will
937cause most of the rest of the core L<IO> modules to falsely report
938having been loaded, due to the way the base L<IO> module works.
939
940=item B<Class::MOP::get_code_info($code)>
941
942This function returns two values, the name of the package the C<$code>
943is from and the name of the C<$code> itself. This is used by several
944elements of the MOP to determine where a given C<$code> reference is
945from.
946
947=item B<Class::MOP::class_of($instance_or_class_name)>
948
949This will return the metaclass of the given instance or class name. If the
950class lacks a metaclass, no metaclass will be initialized, and C<undef> will be
951returned.
952
953=item B<Class::MOP::check_package_cache_flag($pkg)>
954
955B<NOTE: DO NOT USE THIS FUNCTION, IT IS FOR INTERNAL USE ONLY!>
956
957This will return an integer that is managed by L<Class::MOP::Class> to
958determine if a module's symbol table has been altered.
959
960In Perl 5.10 or greater, this flag is package specific. However in
961versions prior to 5.10, this will use the C<PL_sub_generation>
962variable which is not package specific.
963
964=item B<Class::MOP::load_first_existing_class(@class_names)>
965
966B<NOTE: DO NOT USE THIS FUNCTION, IT IS FOR INTERNAL USE ONLY!>
967
968Given a list of class names, this function will attempt to load each
969one in turn.
970
971If it finds a class it can load, it will return that class' name. If
972none of the classes can be loaded, it will throw an exception.
973
974=back
975
976=head2 Metaclass cache functions
977
978Class::MOP holds a cache of metaclasses. The following are functions
979(B<not methods>) which can be used to access that cache. It is not
980recommended that you mess with these. Bad things could happen, but if
981you are brave and willing to risk it: go for it!
982
983=over 4
984
985=item B<Class::MOP::get_all_metaclasses>
986
987This will return a hash of all the metaclass instances that have
988been cached by L<Class::MOP::Class>, keyed by the package name.
989
990=item B<Class::MOP::get_all_metaclass_instances>
991
992This will return a list of all the metaclass instances that have
993been cached by L<Class::MOP::Class>.
994
995=item B<Class::MOP::get_all_metaclass_names>
996
997This will return a list of all the metaclass names that have
998been cached by L<Class::MOP::Class>.
999
1000=item B<Class::MOP::get_metaclass_by_name($name)>
1001
1002This will return a cached L<Class::MOP::Class> instance, or nothing
1003if no metaclass exists with that C<$name>.
1004
1005=item B<Class::MOP::store_metaclass_by_name($name, $meta)>
1006
1007This will store a metaclass in the cache at the supplied C<$key>.
1008
1009=item B<Class::MOP::weaken_metaclass($name)>
1010
1011In rare cases (e.g. anonymous metaclasses) it is desirable to
1012store a weakened reference in the metaclass cache. This
1013function will weaken the reference to the metaclass stored
1014in C<$name>.
1015
1016=item B<Class::MOP::does_metaclass_exist($name)>
1017
1018This will return true of there exists a metaclass stored in the
1019C<$name> key, and return false otherwise.
1020
1021=item B<Class::MOP::remove_metaclass_by_name($name)>
1022
1023This will remove the metaclass stored in the C<$name> key.

1054An excellent paper by the people who brought us the original Traits paper.
1055This paper is on how Traits can be used to do safe metaclass composition,
1056and offers an excellent introduction section which delves into the topic of
1057metaclass compatibility.

1063This paper seems to precede the above paper, and propose a mix-in based

1103like this module is L<Class::Meta>, although it's philosophy and the MOP it
1104creates are very different from this modules.
