431 | =head1 DESCRIPTION |
432 | |
433 | This module provides Mouse with the ability to create custom type |
434 | constraints to be used in attribute definition. |
435 | |
436 | =head2 Important Caveat |
437 | |
438 | This is B<NOT> a type system for Perl 5. These are type constraints, |
439 | and they are not used by Mouse unless you tell it to. No type |
440 | inference is performed, expressions are not typed, etc. etc. etc. |
441 | |
442 | A type constraint is at heart a small "check if a value is valid" |
443 | function. A constraint can be associated with an attribute. This |
444 | simplifies parameter validation, and makes your code clearer to read, |
445 | because you can refer to constraints by name. |
446 | |
447 | =head2 Slightly Less Important Caveat |
448 | |
449 | It is B<always> a good idea to quote your type names. |
450 | |
451 | This prevents Perl from trying to execute the call as an indirect |
452 | object call. This can be an issue when you have a subtype with the |
453 | same name as a valid class. |
454 | |
455 | For instance: |
456 | |
457 | subtype DateTime => as Object => where { $_->isa('DateTime') }; |
458 | |
459 | will I<just work>, while this: |
460 | |
461 | use DateTime; |
462 | subtype DateTime => as Object => where { $_->isa('DateTime') }; |
463 | |
464 | will fail silently and cause many headaches. The simple way to solve |
465 | this, as well as future proof your subtypes from classes which have |
466 | yet to have been created, is to quote the type name: |
467 | |
468 | use DateTime; |
469 | subtype 'DateTime' => as 'Object' => where { $_->isa('DateTime') }; |
470 | |
471 | =head2 Default Type Constraints |
472 | |
473 | This module also provides a simple hierarchy for Perl 5 types, here is |
474 | that hierarchy represented visually. |
475 | |
476 | Any |
477 | Item |
478 | Bool |
479 | Maybe[`a] |
480 | Undef |
481 | Defined |
482 | Value |
483 | Num |
484 | Int |
485 | Str |
486 | ClassName |
487 | RoleName |
488 | Ref |
489 | ScalarRef |
490 | ArrayRef[`a] |
491 | HashRef[`a] |
492 | CodeRef |
493 | RegexpRef |
494 | GlobRef |
495 | FileHandle |
496 | Object |
497 | Role |
498 | |
499 | B<NOTE:> Any type followed by a type parameter C<[`a]> can be |
500 | parameterized, this means you can say: |
501 | |
502 | ArrayRef[Int] # an array of integers |
503 | HashRef[CodeRef] # a hash of str to CODE ref mappings |
504 | Maybe[Str] # value may be a string, may be undefined |
505 | |
506 | If Mouse finds a name in brackets that it does not recognize as an |
507 | existing type, it assumes that this is a class name, for example |
508 | C<ArrayRef[DateTime]>. |
509 | |
510 | B<NOTE:> Unless you parameterize a type, then it is invalid to include |
511 | the square brackets. I.e. C<ArrayRef[]> will be treated as a new type |
512 | name, I<not> as a parameterization of C<ArrayRef>. |
513 | |
514 | B<NOTE:> The C<Undef> type constraint for the most part works |
515 | correctly now, but edge cases may still exist, please use it |
516 | sparingly. |
517 | |
518 | B<NOTE:> The C<ClassName> type constraint does a complex package |
519 | existence check. This means that your class B<must> be loaded for this |
520 | type constraint to pass. |
521 | |
522 | B<NOTE:> The C<RoleName> constraint checks a string is a I<package |
523 | name> which is a role, like C<'MyApp::Role::Comparable'>. The C<Role> |
524 | constraint checks that an I<object does> the named role. |
525 | |
526 | =head2 Type Constraint Naming |
527 | |
528 | Type name declared via this module can only contain alphanumeric |
529 | characters, colons (:), and periods (.). |
530 | |
531 | Since the types created by this module are global, it is suggested |
532 | that you namespace your types just as you would namespace your |
533 | modules. So instead of creating a I<Color> type for your |
534 | B<My::Graphics> module, you would call the type |
535 | I<My::Graphics::Types::Color> instead. |
536 | |
537 | =head2 Use with Other Constraint Modules |
538 | |
539 | This module can play nicely with other constraint modules with some |
540 | slight tweaking. The C<where> clause in types is expected to be a |
541 | C<CODE> reference which checks it's first argument and returns a |
542 | boolean. Since most constraint modules work in a similar way, it |
543 | should be simple to adapt them to work with Mouse. |
544 | |
545 | For instance, this is how you could use it with |
546 | L<Declare::Constraints::Simple> to declare a completely new type. |
547 | |
548 | type 'HashOfArrayOfObjects', |
549 | { |
550 | where => IsHashRef( |
551 | -keys => HasLength, |
552 | -values => IsArrayRef(IsObject) |
553 | ) |
554 | }; |
555 | |
556 | Here is an example of using L<Test::Deep> and it's non-test |
557 | related C<eq_deeply> function. |
558 | |
559 | type 'ArrayOfHashOfBarsAndRandomNumbers' |
560 | => where { |
561 | eq_deeply($_, |
562 | array_each(subhashof({ |
563 | bar => isa('Bar'), |
564 | random_number => ignore() |
565 | }))) |
566 | }; |
