510 | =head1 NAME | |||
511 | ||||
512 | Moose::Meta::Class - The Moose metaclass | |||
513 | ||||
514 | =head1 DESCRIPTION | |||
515 | ||||
516 | This class is a subclass of L<Class::MOP::Class> that provides | |||
517 | additional Moose-specific functionality. | |||
518 | ||||
519 | To really understand this class, you will need to start with the | |||
520 | L<Class::MOP::Class> documentation. This class can be understood as a | |||
521 | set of additional features on top of the basic feature provided by | |||
522 | that parent class. | |||
523 | ||||
524 | =head1 INHERITANCE | |||
525 | ||||
526 | C<Moose::Meta::Class> is a subclass of L<Class::MOP::Class>. | |||
527 | ||||
528 | =head1 METHODS | |||
529 | ||||
530 | =over 4 | |||
531 | ||||
532 | =item B<< Moose::Meta::Class->initialize($package_name, %options) >> | |||
533 | ||||
534 | This overrides the parent's method in order to provide its own | |||
535 | defaults for the C<attribute_metaclass>, C<instance_metaclass>, and | |||
536 | C<method_metaclass> options. | |||
537 | ||||
538 | These all default to the appropriate Moose class. | |||
539 | ||||
540 | =item B<< Moose::Meta::Class->create($package_name, %options) >> | |||
541 | ||||
542 | This overrides the parent's method in order to accept a C<roles> | |||
543 | option. This should be an array reference containing roles | |||
544 | that the class does, each optionally followed by a hashref of options | |||
545 | (C<-excludes> and C<-alias>). | |||
546 | ||||
547 | my $metaclass = Moose::Meta::Class->create( 'New::Class', roles => [...] ); | |||
548 | ||||
549 | =item B<< Moose::Meta::Class->create_anon_class >> | |||
550 | ||||
551 | This overrides the parent's method to accept a C<roles> option, just | |||
552 | as C<create> does. | |||
553 | ||||
554 | It also accepts a C<cache> option. If this is true, then the anonymous | |||
555 | class will be cached based on its superclasses and roles. If an | |||
556 | existing anonymous class in the cache has the same superclasses and | |||
557 | roles, it will be reused. | |||
558 | ||||
559 | my $metaclass = Moose::Meta::Class->create_anon_class( | |||
560 | superclasses => ['Foo'], | |||
561 | roles => [qw/Some Roles Go Here/], | |||
562 | cache => 1, | |||
563 | ); | |||
564 | ||||
565 | Each entry in both the C<superclasses> and the C<roles> option can be | |||
566 | followed by a hash reference with arguments. The C<superclasses> | |||
567 | option can be supplied with a L<-version|Class::MOP/Class Loading | |||
568 | Options> option that ensures the loaded superclass satisfies the | |||
569 | required version. The C<role> option also takes the C<-version> as an | |||
570 | argument, but the option hash reference can also contain any other | |||
571 | role relevant values like exclusions or parameterized role arguments. | |||
572 | ||||
573 | =item B<< $metaclass->make_immutable(%options) >> | |||
574 | ||||
575 | This overrides the parent's method to add a few options. Specifically, | |||
576 | it uses the Moose-specific constructor and destructor classes, and | |||
577 | enables inlining the destructor. | |||
578 | ||||
579 | Since Moose always inlines attributes, it sets the C<inline_accessors> option | |||
580 | to false. | |||
581 | ||||
582 | =item B<< $metaclass->new_object(%params) >> | |||
583 | ||||
584 | This overrides the parent's method in order to add support for | |||
585 | attribute triggers. | |||
586 | ||||
587 | =item B<< $metaclass->superclasses(@superclasses) >> | |||
588 | ||||
589 | This is the accessor allowing you to read or change the parents of | |||
590 | the class. | |||
591 | ||||
592 | Each superclass can be followed by a hash reference containing a | |||
593 | L<-version|Class::MOP/Class Loading Options> value. If the version | |||
594 | requirement is not satisfied an error will be thrown. | |||
595 | ||||
596 | =item B<< $metaclass->add_override_method_modifier($name, $sub) >> | |||
597 | ||||
598 | This adds an C<override> method modifier to the package. | |||
599 | ||||
600 | =item B<< $metaclass->add_augment_method_modifier($name, $sub) >> | |||
601 | ||||
602 | This adds an C<augment> method modifier to the package. | |||
603 | ||||
604 | =item B<< $metaclass->calculate_all_roles >> | |||
605 | ||||
606 | This will return a unique array of C<Moose::Meta::Role> instances | |||
607 | which are attached to this class. | |||
608 | ||||
609 | =item B<< $metaclass->calculate_all_roles_with_inheritance >> | |||
610 | ||||
611 | This will return a unique array of C<Moose::Meta::Role> instances | |||
612 | which are attached to this class, and each of this class's ancestors. | |||
613 | ||||
614 | =item B<< $metaclass->add_role($role) >> | |||
615 | ||||
616 | This takes a L<Moose::Meta::Role> object, and adds it to the class's | |||
617 | list of roles. This I<does not> actually apply the role to the class. | |||
618 | ||||
619 | =item B<< $metaclass->role_applications >> | |||
620 | ||||
621 | Returns a list of L<Moose::Meta::Role::Application::ToClass> | |||
622 | objects, which contain the arguments to role application. | |||
623 | ||||
624 | =item B<< $metaclass->add_role_application($application) >> | |||
625 | ||||
626 | This takes a L<Moose::Meta::Role::Application::ToClass> object, and | |||
627 | adds it to the class's list of role applications. This I<does not> | |||
628 | actually apply any role to the class; it is only for tracking role | |||
629 | applications. | |||
630 | ||||
631 | =item B<< $metaclass->does_role($role) >> | |||
632 | ||||
633 | This returns a boolean indicating whether or not the class does the specified | |||
634 | role. The role provided can be either a role name or a L<Moose::Meta::Role> | |||
635 | object. This tests both the class and its parents. | |||
636 | ||||
637 | =item B<< $metaclass->excludes_role($role_name) >> | |||
638 | ||||
639 | A class excludes a role if it has already composed a role which | |||
640 | excludes the named role. This tests both the class and its parents. | |||
641 | ||||
642 | =item B<< $metaclass->add_attribute($attr_name, %params|$params) >> | |||
643 | ||||
644 | This overrides the parent's method in order to allow the parameters to | |||
645 | be provided as a hash reference. | |||
646 | ||||
647 | =item B<< $metaclass->constructor_class($class_name) >> | |||
648 | ||||
649 | =item B<< $metaclass->destructor_class($class_name) >> | |||
650 | ||||
651 | These are the names of classes used when making a class immutable. These | |||
652 | default to L<Moose::Meta::Method::Constructor> and | |||
653 | L<Moose::Meta::Method::Destructor> respectively. These accessors are | |||
654 | read-write, so you can use them to change the class name. | |||
655 | ||||
656 | =item B<< $metaclass->error_class($class_name) >> | |||
657 | ||||
658 | The name of the class used to throw errors. This defaults to | |||
659 | L<Moose::Error::Default>, which generates an error with a stacktrace | |||
660 | just like C<Carp::confess>. | |||
661 | ||||
662 | =item B<< $metaclass->throw_error($message, %extra) >> | |||
663 | ||||
664 | Throws the error created by C<create_error> using C<raise_error> | |||
665 | ||||
