| 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> | |||
