465 | |

466 | Moose::Meta::Class - The Moose metaclass |
c0e30cf5 |
467 | |
c0e30cf5 |
468 | =head1 DESCRIPTION |
469 | |
ac2dc464 |
470 | This is a subclass of L<Class::MOP::Class> with Moose specific |
e522431d |
471 | extensions. |
472 | |
ac2dc464 |
473 | For the most part, the only time you will ever encounter an |
474 | instance of this class is if you are doing some serious deep |
475 | introspection. To really understand this class, you need to refer |
6ba6d68c |
476 | to the L<Class::MOP::Class> documentation. |

478 | =head1 METHODS |

590868a3 |
482 | =item B<initialize> |
483 | |
61bdd94f |
484 | =item B<create> |
485 | |
17594769 |
486 | Overrides original to accept a list of roles to apply to |
61bdd94f |
487 | the created class. |
488 | |
17594769 |
489 | my $metaclass = Moose::Meta::Class->create( 'New::Class', roles => [...] ); |
490 | |
491 | =item B<create_anon_class> |
492 | |
493 | Overrides original to support roles and caching. |
494 | |
495 | my $metaclass = Moose::Meta::Class->create_anon_class( |
496 | superclasses => ['Foo'], |
497 | roles => [qw/Some Roles Go Here/], |
498 | cache => 1, |
499 | ); |
500 | |
5cf3dbcf |
501 | =item B<make_immutable> |
502 | |
ac2dc464 |
503 | Override original to add default options for inlining destructor |
504 | and altering the Constructor metaclass. |
505 | |
506 | =item B<create_immutable_transformer> |
507 | |
508 | Override original to lock C<add_role> and memoize C<calculate_all_roles> |
509 | |
8c9d74e7 |
510 | =item B<new_object> |
511 | |
02a0fb52 |
512 | We override this method to support the C<trigger> attribute option. |
513 | |
a15dff8d |
514 | =item B<construct_instance> |
515 | |
ac2dc464 |
516 | This provides some Moose specific extensions to this method, you |
517 | almost never call this method directly unless you really know what |
518 | you are doing. |
6ba6d68c |
519 | |
520 | This method makes sure to handle the moose weak-ref, type-constraint |
ac2dc464 |
521 | and type coercion features. |
ef1d5f4b |
522 | |
093b12c2 |
523 | =item B<get_method_map> |
e9ec68d6 |
524 | |
ac2dc464 |
525 | This accommodates Moose::Meta::Role::Method instances, which are |
526 | aliased, instead of added, but still need to be counted as valid |
e9ec68d6 |
527 | methods. |
528 | |
78cd1d3b |
529 | =item B<add_override_method_modifier ($name, $method)> |
530 | |
ac2dc464 |
531 | This will create an C<override> method modifier for you, and install |
02a0fb52 |
532 | it in the package. |
533 | |
78cd1d3b |
534 | =item B<add_augment_method_modifier ($name, $method)> |
535 | |
ac2dc464 |
536 | This will create an C<augment> method modifier for you, and install |
02a0fb52 |
537 | it in the package. |
538 | |
2b14ac61 |
539 | =item B<calculate_all_roles> |
540 | |
ef333f17 |
541 | =item B<roles> |
542 | |
ac2dc464 |
543 | This will return an array of C<Moose::Meta::Role> instances which are |
02a0fb52 |
544 | attached to this class. |
545 | |
ef333f17 |
546 | =item B<add_role ($role)> |
547 | |
ac2dc464 |
548 | This takes an instance of C<Moose::Meta::Role> in C<$role>, and adds it |
02a0fb52 |
549 | to the list of associated roles. |
550 | |
ef333f17 |
551 | =item B<does_role ($role_name)> |
552 | |
ac2dc464 |
553 | This will test if this class C<does> a given C<$role_name>. It will |
554 | not only check it's local roles, but ask them as well in order to |
02a0fb52 |
555 | cascade down the role hierarchy. |
556 | |
d79e62fd |
557 | =item B<excludes_role ($role_name)> |
558 | |
ac2dc464 |
559 | This will test if this class C<excludes> a given C<$role_name>. It will |
560 | not only check it's local roles, but ask them as well in order to |
d79e62fd |
561 | cascade down the role hierarchy. |
562 | |
9e93dd19 |
563 | =item B<add_attribute ($attr_name, %params|$params)> |
4e848edb |
564 | |
9e93dd19 |
565 | This method does the same thing as L<Class::MOP::Class::add_attribute>, but adds |
566 | support for taking the C<$params> as a HASH ref. |
