519 | =head1 NAME |
520 | |
e522431d |
521 | Moose::Meta::Class - The Moose metaclass |
c0e30cf5 |
522 | |
c0e30cf5 |
523 | =head1 DESCRIPTION |
524 | |
ac2dc464 |
525 | This is a subclass of L<Class::MOP::Class> with Moose specific |
e522431d |
526 | extensions. |
527 | |
ac2dc464 |
528 | For the most part, the only time you will ever encounter an |
529 | instance of this class is if you are doing some serious deep |
530 | introspection. To really understand this class, you need to refer |
6ba6d68c |
531 | to the L<Class::MOP::Class> documentation. |
532 | |

533 | =head1 METHODS |

537 | =item B<initialize> |
538 | |
61bdd94f |
539 | =item B<create> |
540 | |
17594769 |
541 | Overrides original to accept a list of roles to apply to |
61bdd94f |
542 | the created class. |
543 | |
17594769 |
544 | my $metaclass = Moose::Meta::Class->create( 'New::Class', roles => [...] ); |
545 | |
546 | =item B<create_anon_class> |
547 | |
548 | Overrides original to support roles and caching. |
549 | |
550 | my $metaclass = Moose::Meta::Class->create_anon_class( |
551 | superclasses => ['Foo'], |
552 | roles => [qw/Some Roles Go Here/], |
553 | cache => 1, |
554 | ); |
555 | |
5cf3dbcf |
556 | =item B<make_immutable> |
557 | |
ac2dc464 |
558 | Override original to add default options for inlining destructor |
559 | and altering the Constructor metaclass. |
560 | |
561 | =item B<create_immutable_transformer> |
562 | |
563 | Override original to lock C<add_role> and memoize C<calculate_all_roles> |
564 | |
8c9d74e7 |
565 | =item B<new_object> |
566 | |
02a0fb52 |
567 | We override this method to support the C<trigger> attribute option. |
568 | |
a15dff8d |
569 | =item B<construct_instance> |
570 | |
ac2dc464 |
571 | This provides some Moose specific extensions to this method, you |
572 | almost never call this method directly unless you really know what |
573 | you are doing. |
6ba6d68c |
574 | |
575 | This method makes sure to handle the moose weak-ref, type-constraint |
ac2dc464 |
576 | and type coercion features. |
ef1d5f4b |
577 | |
093b12c2 |
578 | =item B<get_method_map> |
e9ec68d6 |
579 | |
ac2dc464 |
580 | This accommodates Moose::Meta::Role::Method instances, which are |
581 | aliased, instead of added, but still need to be counted as valid |
e9ec68d6 |
582 | methods. |
583 | |
78cd1d3b |
584 | =item B<add_override_method_modifier ($name, $method)> |
585 | |
ac2dc464 |
586 | This will create an C<override> method modifier for you, and install |
02a0fb52 |
587 | it in the package. |
588 | |
78cd1d3b |
589 | =item B<add_augment_method_modifier ($name, $method)> |
590 | |
ac2dc464 |
591 | This will create an C<augment> method modifier for you, and install |
02a0fb52 |
592 | it in the package. |
593 | |
2b14ac61 |
594 | =item B<calculate_all_roles> |
595 | |
ef333f17 |
596 | =item B<roles> |
597 | |
ac2dc464 |
598 | This will return an array of C<Moose::Meta::Role> instances which are |
02a0fb52 |
599 | attached to this class. |
600 | |
ef333f17 |
601 | =item B<add_role ($role)> |
602 | |
ac2dc464 |
603 | This takes an instance of C<Moose::Meta::Role> in C<$role>, and adds it |
02a0fb52 |
604 | to the list of associated roles. |
605 | |
ef333f17 |
606 | =item B<does_role ($role_name)> |
607 | |
ac2dc464 |
608 | This will test if this class C<does> a given C<$role_name>. It will |
609 | not only check it's local roles, but ask them as well in order to |
02a0fb52 |
610 | cascade down the role hierarchy. |
611 | |
d79e62fd |
612 | =item B<excludes_role ($role_name)> |
613 | |
ac2dc464 |
614 | This will test if this class C<excludes> a given C<$role_name>. It will |
615 | not only check it's local roles, but ask them as well in order to |
d79e62fd |
616 | cascade down the role hierarchy. |
617 | |
9e93dd19 |
618 | =item B<add_attribute ($attr_name, %params|$params)> |
4e848edb |
619 | |
9e93dd19 |
620 | This method does the same thing as L<Class::MOP::Class::add_attribute>, but adds |
621 | support for taking the C<$params> as a HASH ref. |
ac1ef2f9 |
622 | |
11c86f15 |
623 | =item B<throw_error $message, %extra> |
624 | |
625 | Throws the error created by C<create_error> using C<raise_error> |
626 | |
627 | =item B<create_error $message, %extra> |
628 | |
629 | Creates an error message or object. |
630 | |
631 | The default behavior is C<create_error_confess>. |
632 | |
633 | If C<error_class> is set uses C<create_error_object>. Otherwise uses |
634 | C<error_builder> (a code reference or variant name), and calls the appropriate |
635 | C<create_error_$builder> method. |
636 | |
637 | =item B<error_builder $builder_name> |
638 | |
639 | Get or set the error builder. Defaults to C<confess>. |
640 | |
641 | =item B<error_class $class_name> |
642 | |
643 | Get or set the error class. Has no default. |
644 | |
645 | =item B<create_error_confess %args> |
646 | |
647 | Creates an error using L<Carp/longmess> |
648 | |
649 | =item B<create_error_croak %args> |
650 | |
651 | Creates an error using L<Carp/shortmess> |
652 | |
653 | =item B<create_error_object %args> |
654 | |
655 | Calls C<new> on the C<class> parameter in C<%args>. Usable with C<error_class> |
656 | to support custom error objects for your meta class. |
657 | |
658 | =item B<raise_error $error> |
659 | |
660 | Dies with an error object or string. |
