296 | # Right now, this method does not handle the case where two |

298 | # class. This can happen fairly easily when ClassA applies metaclass |
299 | # Role1, and then a subclass, ClassB, applies a metaclass Role2. In |
300 | # reality, the way to resolve the problem is to apply Role1 to |
301 | # ClassB's metaclass. However, we cannot currently detect this, and so |
302 | # we simply fail to fix the incompatibility. |
303 | # |
304 | # The algorithm for fixing it is not that complicated. |

307 | # Moose::Meta::Class). |

310 | # applied. This second point is where things break down. There is no |

312 | # that, we'd need to able to reliably determine the origin of each |
313 | # method and attribute in each metaclass. If all the unshared methods |
314 | # & attributes come from roles, and there is no name collision, then |
315 | # we can apply the missing roles to the child's metaclass. |

477 | |

478 | Moose::Meta::Class - The Moose metaclass |
c0e30cf5 |
479 | |
c0e30cf5 |
480 | =head1 DESCRIPTION |
481 | |
ac2dc464 |
482 | This is a subclass of L<Class::MOP::Class> with Moose specific |
e522431d |
483 | extensions. |
484 | |
ac2dc464 |
485 | For the most part, the only time you will ever encounter an |
486 | instance of this class is if you are doing some serious deep |
487 | introspection. To really understand this class, you need to refer |
6ba6d68c |
488 | to the L<Class::MOP::Class> documentation. |

490 | =head1 METHODS |

494 | =item B<initialize> |
495 | |
61bdd94f |
496 | =item B<create> |
497 | |
17594769 |
498 | Overrides original to accept a list of roles to apply to |
61bdd94f |
499 | the created class. |
500 | |
17594769 |
501 | my $metaclass = Moose::Meta::Class->create( 'New::Class', roles => [...] ); |
502 | |
503 | =item B<create_anon_class> |
504 | |
505 | Overrides original to support roles and caching. |
506 | |
507 | my $metaclass = Moose::Meta::Class->create_anon_class( |
508 | superclasses => ['Foo'], |
509 | roles => [qw/Some Roles Go Here/], |
510 | cache => 1, |
511 | ); |
512 | |
5cf3dbcf |
513 | =item B<make_immutable> |
514 | |
ac2dc464 |
515 | Override original to add default options for inlining destructor |
516 | and altering the Constructor metaclass. |
517 | |
518 | =item B<create_immutable_transformer> |
519 | |
520 | Override original to lock C<add_role> and memoize C<calculate_all_roles> |
521 | |
65e14c86 |
522 | =item B<new_object> |
523 | |
524 | We override this method to support the C<trigger> attribute option. |
525 | |
a15dff8d |
526 | =item B<construct_instance> |
527 | |
ac2dc464 |
528 | This provides some Moose specific extensions to this method, you |
529 | almost never call this method directly unless you really know what |
530 | you are doing. |
6ba6d68c |
531 | |
532 | This method makes sure to handle the moose weak-ref, type-constraint |
ac2dc464 |
533 | and type coercion features. |
ef1d5f4b |
534 | |
093b12c2 |
535 | =item B<get_method_map> |
e9ec68d6 |
536 | |
ac2dc464 |
537 | This accommodates Moose::Meta::Role::Method instances, which are |
538 | aliased, instead of added, but still need to be counted as valid |
e9ec68d6 |
539 | methods. |
540 | |
78cd1d3b |
541 | =item B<add_override_method_modifier ($name, $method)> |
542 | |
ac2dc464 |
543 | This will create an C<override> method modifier for you, and install |
02a0fb52 |
544 | it in the package. |
545 | |
78cd1d3b |
546 | =item B<add_augment_method_modifier ($name, $method)> |
547 | |
ac2dc464 |
548 | This will create an C<augment> method modifier for you, and install |
02a0fb52 |
549 | it in the package. |
550 | |
2b14ac61 |
551 | =item B<calculate_all_roles> |
552 | |
ef333f17 |
553 | =item B<roles> |
554 | |
ac2dc464 |
555 | This will return an array of C<Moose::Meta::Role> instances which are |
02a0fb52 |
556 | attached to this class. |
557 | |
ef333f17 |
558 | =item B<add_role ($role)> |
559 | |
ac2dc464 |
560 | This takes an instance of C<Moose::Meta::Role> in C<$role>, and adds it |
02a0fb52 |
561 | to the list of associated roles. |
562 | |
ef333f17 |
563 | =item B<does_role ($role_name)> |
564 | |
ac2dc464 |
565 | This will test if this class C<does> a given C<$role_name>. It will |
566 | not only check it's local roles, but ask them as well in order to |
02a0fb52 |
567 | cascade down the role hierarchy. |
568 | |
d79e62fd |
569 | =item B<excludes_role ($role_name)> |
570 | |
ac2dc464 |
571 | This will test if this class C<excludes> a given C<$role_name>. It will |
572 | not only check it's local roles, but ask them as well in order to |
d79e62fd |
573 | cascade down the role hierarchy. |
574 | |
9e93dd19 |
575 | =item B<add_attribute ($attr_name, %params|$params)> |
4e848edb |
576 | |
9e93dd19 |
577 | This method does the same thing as L<Class::MOP::Class::add_attribute>, but adds |
578 | support for taking the C<$params> as a HASH ref. |
