443 | =head1 NAME |
444 | |
6ba6d68c |
445 | Moose::Meta::Attribute - The Moose attribute metaclass |
c0e30cf5 |
446 | |
447 | =head1 DESCRIPTION |
448 | |
e522431d |
449 | This is a subclass of L<Class::MOP::Attribute> with Moose specific |
6ba6d68c |
450 | extensions. |
451 | |
452 | For the most part, the only time you will ever encounter an |
453 | instance of this class is if you are doing some serious deep |
454 | introspection. To really understand this class, you need to refer |
455 | to the L<Class::MOP::Attribute> documentation. |

457 | =head1 METHODS |
458 | |
6ba6d68c |
459 | =head2 Overridden methods |
460 | |
461 | These methods override methods in L<Class::MOP::Attribute> and add |
462 | Moose specific features. You can safely assume though that they |
463 | will behave just as L<Class::MOP::Attribute> does. |

481 | =head2 Additional Moose features |
482 | |
8449e6e7 |
483 | Moose attributes support type-constraint checking, weak reference |
6ba6d68c |
484 | creation and type coercion. |

487 | |

488 | =item B<clone_and_inherit_options> |
489 | |
490 | This is to support the C<has '+foo'> feature, it clones an attribute |
491 | from a superclass and allows a very specific set of changes to be made |
492 | to the attribute. |
493 | |
a15dff8d |
494 | =item B<has_type_constraint> |
495 | |
6ba6d68c |
496 | Returns true if this meta-attribute has a type constraint. |
497 | |
a15dff8d |
498 | =item B<type_constraint> |
499 | |
6ba6d68c |
500 | A read-only accessor for this meta-attribute's type constraint. For |
501 | more information on what you can do with this, see the documentation |
502 | for L<Moose::Meta::TypeConstraint>. |
a15dff8d |
503 | |

504 | =item B<has_handles> |
505 | |
506 | Returns true if this meta-attribute performs delegation. |
507 | |
508 | =item B<handles> |
509 | |
510 | This returns the value which was passed into the handles option. |
511 | |
6ba6d68c |
512 | =item B<is_weak_ref> |
a15dff8d |
513 | |
02a0fb52 |
514 | Returns true if this meta-attribute produces a weak reference. |
4b598ea3 |
515 | |
ca01a97b |
516 | =item B<is_required> |
517 | |
02a0fb52 |
518 | Returns true if this meta-attribute is required to have a value. |
ca01a97b |
519 | |
520 | =item B<is_lazy> |
521 | |
02a0fb52 |
522 | Returns true if this meta-attribute should be initialized lazily. |
ca01a97b |
523 | |
524 | NOTE: lazy attributes, B<must> have a C<default> field set. |
525 | |
34a66aa3 |
526 | =item B<should_coerce> |
4b598ea3 |
527 | |
02a0fb52 |
528 | Returns true if this meta-attribute should perform type coercion. |
6ba6d68c |
529 | |
536f0b17 |
530 | =item B<should_auto_deref> |
531 | |
532 | Returns true if this meta-attribute should perform automatic |
533 | auto-dereferencing. |
534 | |
535 | NOTE: This can only be done for attributes whose type constraint is |
536 | either I<ArrayRef> or I<HashRef>. |
537 | |
8c9d74e7 |
538 | =item B<has_trigger> |
539 | |
02a0fb52 |
540 | Returns true if this meta-attribute has a trigger set. |
541 | |
8c9d74e7 |
542 | =item B<trigger> |
543 | |
02a0fb52 |
544 | This is a CODE reference which will be executed every time the |
545 | value of an attribute is assigned. The CODE ref will get two values, |
546 | the invocant and the new value. This can be used to handle I<basic> |
547 | bi-directional relations. |
548 | |
ddbdc0cb |
549 | =item B<documentation> |
550 | |
551 | This is a string which contains the documentation for this attribute. |
552 | It serves no direct purpose right now, but it might in the future |
553 | in some kind of automated documentation system perhaps. |
554 | |
555 | =item B<has_documentation> |
556 | |
557 | Returns true if this meta-attribute has any documentation. |
