477 | =head1 DESCRIPTION |
478 | |
2c3bf4e7 |
479 | This module provides a set of utility functions. Many of these |
480 | functions are intended for use in Moose itself or MooseX modules, but |
481 | some of them may be useful for use in your own code. |

485 | =over 4 |
486 | |
2c3bf4e7 |
487 | =item B<find_meta($class_or_obj)> |
488 | |
489 | This method takes a class name or object and attempts to find a |
3ff98e47 |
490 | metaclass for the class, if one exists. It will B<not> create one if it |
2c3bf4e7 |
491 | does not yet exist. |
492 | |
560c498d |
493 | =item B<does_role($class_or_obj, $role_or_obj)> |
2c3bf4e7 |
494 | |
560c498d |
495 | Returns true if C<$class_or_obj> does the given C<$role_or_obj>. The role can |
496 | be provided as a name or a L<Moose::Meta::Role> object. |
6532ca5a |
497 | |
560c498d |
498 | The class must already have a metaclass for this to work. If it doesn't, this |
499 | function simply returns false. |
6532ca5a |
500 | |
560c498d |
501 | =item B<search_class_by_role($class_or_obj, $role_or_obj)> |
7125b244 |
502 | |
2c3bf4e7 |
503 | Returns the first class in the class's precedence list that does |
560c498d |
504 | C<$role_or_obj>, if any. The role can be either a name or a |
505 | L<Moose::Meta::Role> object. |
7125b244 |
506 | |
2c3bf4e7 |
507 | The class must already have a metaclass for this to work. |
7125b244 |
508 | |
2c3bf4e7 |
509 | =item B<apply_all_roles($applicant, @roles)> |
7125b244 |
510 | |
2c3bf4e7 |
511 | This function applies one or more roles to the given C<$applicant> The |
512 | applicant can be a role name, class name, or object. |
d7d8a8c7 |
513 | |
2c3bf4e7 |
514 | The C<$applicant> must already have a metaclass object. |
515 | |
560c498d |
516 | The list of C<@roles> should a list of names or L<Moose::Meta::Role> objects, |
517 | each of which can be followed by an optional hash reference of options |
518 | (C<-excludes> and C<-alias>). |
d7d8a8c7 |
519 | |
b099a649 |
520 | =item B<ensure_all_roles($applicant, @roles)> |
521 | |
522 | This function is similar to L</apply_all_roles>, but only applies roles that |
523 | C<$applicant> does not already consume. |
524 | |
d26f5671 |
525 | =item B<with_traits($class_name, @role_names)> |
526 | |
527 | This function creates a new class from C<$class_name> with each of |
528 | C<@role_names> applied. It returns the name of the new class. |
529 | |
ab76842e |
530 | =item B<get_all_attribute_values($meta, $instance)> |
531 | |
2c3bf4e7 |
532 | Returns a hash reference containing all of the C<$instance>'s |
533 | attributes. The keys are attribute names. |
ab76842e |
534 | |
535 | =item B<get_all_init_args($meta, $instance)> |
536 | |
2c3bf4e7 |
537 | Returns a hash reference containing all of the C<init_arg> values for |
538 | the instance's attributes. The values are the associated attribute |
539 | values. If an attribute does not have a defined C<init_arg>, it is |
540 | skipped. |
541 | |
542 | This could be useful in cloning an object. |
ab76842e |
543 | |
a3738e5b |
544 | =item B<resolve_metaclass_alias($category, $name, %options)> |
545 | |
546 | =item B<resolve_metatrait_alias($category, $name, %options)> |
547 | |
2c3bf4e7 |
548 | Resolves a short name to a full class name. Short names are often used |
549 | when specifying the C<metaclass> or C<traits> option for an attribute: |
a3738e5b |
550 | |
551 | has foo => ( |
552 | metaclass => "Bar", |
553 | ); |
554 | |
8a8856de |
555 | The name resolution mechanism is covered in |
556 | L<Moose/Metaclass and Trait Name Resolution>. |

558 | =item B<meta_class_alias($to[, $from])> |
559 | |
560 | =item B<meta_attribute_alias($to[, $from])> |
561 | |
562 | Create an alias from the class C<$from> (or the current package, if |
563 | C<$from> is unspecified), so that |
564 | L<Moose/Metaclass and Trait Name Resolution> works properly. |
565 | |
57385c0d |
566 | =item B<english_list(@items)> |
567 | |
568 | Given a list of scalars, turns them into a proper list in English |
569 | ("one and two", "one, two, three, and four"). This is used to help us |
570 | make nicer error messages. |
