| 316 | |||||
| 317 | =head1 DESCRIPTION | ||||
| 318 | |||||
| 319 | Moose is an extension of the Perl 5 object system. | ||||
| 320 | |||||
| 321 | The main goal of Moose is to make Perl 5 Object Oriented programming | ||||
| 322 | easier, more consistent and less tedious. With Moose you can to think | ||||
| 323 | more about what you want to do and less about the mechanics of OOP. | ||||
| 324 | |||||
| 325 | Additionally, Moose is built on top of L<Class::MOP>, which is a | ||||
| 326 | metaclass system for Perl 5. This means that Moose not only makes | ||||
| 327 | building normal Perl 5 objects better, but it provides the power of | ||||
| 328 | metaclass programming as well. | ||||
| 329 | |||||
| 330 | =head2 New to Moose? | ||||
| 331 | |||||
| 332 | If you're new to Moose, the best place to start is the | ||||
| 333 | L<Moose::Manual> docs, followed by the L<Moose::Cookbook>. The intro | ||||
| 334 | will show you what Moose is, and how it makes Perl 5 OO better. | ||||
| 335 | |||||
| 336 | The cookbook recipes on Moose basics will get you up to speed with | ||||
| 337 | many of Moose's features quickly. Once you have an idea of what Moose | ||||
| 338 | can do, you can use the API documentation to get more detail on | ||||
| 339 | features which interest you. | ||||
| 340 | |||||
| 341 | =head2 Moose Extensions | ||||
| 342 | |||||
| 343 | The C<MooseX::> namespace is the official place to find Moose extensions. | ||||
| 344 | These extensions can be found on the CPAN. The easiest way to find them | ||||
| 345 | is to search for them (L<http://search.cpan.org/search?query=MooseX::>), | ||||
| 346 | or to examine L<Task::Moose> which aims to keep an up-to-date, easily | ||||
| 347 | installable list of Moose extensions. | ||||
| 348 | |||||
| 349 | =head1 TRANSLATIONS | ||||
| 350 | |||||
| 351 | Much of the Moose documentation has been translated into other languages. | ||||

| 361 | =head1 BUILDING CLASSES WITH MOOSE | ||||
| 362 | |||||
| 363 | Moose makes every attempt to provide as much convenience as possible during | ||||
| 364 | class construction/definition, but still stay out of your way if you want it | ||||
| 365 | to. Here are a few items to note when building classes with Moose. | ||||
| 366 | |||||
| 367 | Unless specified with C<extends>, any class which uses Moose will | ||||
| 368 | inherit from L<Moose::Object>. | ||||
| 369 | |||||
| 370 | Moose will also manage all attributes (including inherited ones) that are | ||||
| 371 | defined with C<has>. And (assuming you call C<new>, which is inherited from | ||||
| 372 | L<Moose::Object>) this includes properly initializing all instance slots, | ||||
| 373 | setting defaults where appropriate, and performing any type constraint checking | ||||
| 374 | or coercion. | ||||
| 375 | |||||
| 376 | =head1 PROVIDED METHODS | ||||
| 377 | |||||
| 378 | Moose provides a number of methods to all your classes, mostly through the | ||||
| 379 | inheritance of L<Moose::Object>. There is however, one exception. | ||||
| 380 | |||||
| 381 | =over 4 | ||||
| 382 | |||||
| 383 | =item B<meta> | ||||
| 384 | |||||
| 385 | This is a method which provides access to the current class's metaclass. | ||||
| 386 | |||||
| 387 | =back | ||||
| 388 | |||||
| 389 | =head1 EXPORTED FUNCTIONS | ||||
| 390 | |||||
| 391 | Moose will export a number of functions into the class's namespace which | ||||
| 392 | may then be used to set up the class. These functions all work directly | ||||
| 393 | on the current class. | ||||
| 394 | |||||
| 395 | =over 4 | ||||
| 396 | |||||
| 397 | =item B<extends (@superclasses)> | ||||
| 398 | |||||
| 399 | This function will set the superclass(es) for the current class. | ||||
| 400 | |||||
| 401 | This approach is recommended instead of C<use base>, because C<use base> | ||||
| 402 | actually C<push>es onto the class's C<@ISA>, whereas C<extends> will | ||||
| 403 | replace it. This is important to ensure that classes which do not have | ||||
| 404 | superclasses still properly inherit from L<Moose::Object>. | ||||
| 405 | |||||
| 406 | =item B<with (@roles)> | ||||
| 407 | |||||
| 408 | This will apply a given set of C<@roles> to the local class. | ||||
| 409 | |||||
| 410 | =item B<has $name|@$names =E<gt> %options> | ||||
| 411 | |||||
| 412 | This will install an attribute of a given C<$name> into the current class. If | ||||
| 413 | the first parameter is an array reference, it will create an attribute for | ||||
| 414 | every C<$name> in the list. The C<%options> are the same as those provided by | ||||
| 415 | L<Class::MOP::Attribute>, in addition to the list below which are provided by | ||||
| 416 | Moose (L<Moose::Meta::Attribute> to be more specific): | ||||
| 417 | |||||
| 418 | =over 4 | ||||
| 419 | |||||
| 420 | =item I<is =E<gt> 'rw'|'ro'> | ||||
| 421 | |||||
| 422 | The I<is> option accepts either I<rw> (for read/write) or I<ro> (for read | ||||
| 423 | only). These will create either a read/write accessor or a read-only | ||||
| 424 | accessor respectively, using the same name as the C<$name> of the attribute. | ||||
| 425 | |||||
| 426 | If you need more control over how your accessors are named, you can | ||||
| 427 | use the L<reader|Class::MOP::Attribute/reader>, | ||||
| 428 | L<writer|Class::MOP::Attribute/writer> and | ||||
| 429 | L<accessor|Class::MOP::Attribute/accessor> options inherited from | ||||
| 430 | L<Class::MOP::Attribute>, however if you use those, you won't need the | ||||
| 431 | I<is> option. | ||||
| 432 | |||||
| 433 | =item I<isa =E<gt> $type_name> | ||||
| 434 | |||||
| 435 | The I<isa> option uses Moose's type constraint facilities to set up runtime | ||||
| 436 | type checking for this attribute. Moose will perform the checks during class | ||||
| 437 | construction, and within any accessors. The C<$type_name> argument must be a | ||||
| 438 | string. The string may be either a class name or a type defined using | ||||
| 439 | Moose's type definition features. (Refer to L<Moose::Util::TypeConstraints> | ||||
| 440 | for information on how to define a new type, and how to retrieve type meta-data). | ||||
| 441 | |||||
| 442 | =item I<coerce =E<gt> (1|0)> | ||||
| 443 | |||||
| 444 | This will attempt to use coercion with the supplied type constraint to change | ||||
| 445 | the value passed into any accessors or constructors. You B<must> have supplied | ||||
| 446 | a type constraint in order for this to work. See L<Moose::Cookbook::Basics::Recipe5> | ||||
| 447 | for an example. | ||||
| 448 | |||||
| 449 | =item I<does =E<gt> $role_name> | ||||
| 450 | |||||
| 451 | This will accept the name of a role which the value stored in this attribute | ||||
| 452 | is expected to have consumed. | ||||
| 453 | |||||
| 454 | =item I<required =E<gt> (1|0)> | ||||
| 455 | |||||
| 456 | This marks the attribute as being required. This means a value must be | ||||
| 457 | supplied during class construction, I<or> the attribute must be lazy | ||||
| 458 | and have either a default or a builder. Note that c<required> does not | ||||
| 459 | say anything about the attribute's value, which can be C<undef>. | ||||
| 460 | |||||
| 461 | =item I<weak_ref =E<gt> (1|0)> | ||||
| 462 | |||||
| 463 | This will tell the class to store the value of this attribute as a weakened | ||||
| 464 | reference. If an attribute is a weakened reference, it B<cannot> also be | ||||
| 465 | coerced. | ||||
| 466 | |||||
| 467 | =item I<lazy =E<gt> (1|0)> | ||||
| 468 | |||||
| 469 | This will tell the class to not create this slot until absolutely necessary. | ||||
| 470 | If an attribute is marked as lazy it B<must> have a default supplied. | ||||
| 471 | |||||
| 472 | =item I<auto_deref =E<gt> (1|0)> | ||||
| 473 | |||||
| 474 | This tells the accessor to automatically dereference the value of this | ||||
| 475 | attribute when called in list context. The accessor will still return a | ||||
| 476 | reference when called in scalar context. If this behavior isn't desirable, | ||||
| 477 | L<Moose::Meta::Attribute::Native::Trait::Array/elements> or | ||||
| 478 | L<Moose::Meta::Attribute::Native::Trait::Hash/elements> may be a better | ||||
| 479 | choice. The I<auto_deref> option is only legal if your I<isa> option is | ||||
| 480 | either C<ArrayRef> or C<HashRef>. | ||||
| 481 | |||||
| 482 | =item I<trigger =E<gt> $code> | ||||
| 483 | |||||
| 484 | The I<trigger> option is a CODE reference which will be called after | ||||
| 485 | the value of the attribute is set. The CODE ref is passed the | ||||
| 486 | instance itself, the updated value, and the original value if the | ||||
| 487 | attribute was already set. | ||||
| 488 | |||||
| 489 | You B<can> have a trigger on a read-only attribute. | ||||
| 490 | |||||
| 491 | B<NOTE:> Triggers will only fire when you B<assign> to the attribute, | ||||
| 492 | either in the constructor, or using the writer. Default and built values will | ||||
| 493 | B<not> cause the trigger to be fired. | ||||
| 494 | |||||
| 495 | =item I<handles =E<gt> ARRAY | HASH | REGEXP | ROLE | ROLETYPE | DUCKTYPE | CODE> | ||||
| 496 | |||||
| 497 | The I<handles> option provides Moose classes with automated delegation features. | ||||
| 498 | This is a pretty complex and powerful option. It accepts many different option | ||||
| 499 | formats, each with its own benefits and drawbacks. | ||||
| 500 | |||||
| 501 | B<NOTE:> The class being delegated to does not need to be a Moose based class, | ||||
| 502 | which is why this feature is especially useful when wrapping non-Moose classes. | ||||
| 503 | |||||
| 504 | All I<handles> option formats share the following traits: | ||||
| 505 | |||||
| 506 | You cannot override a locally defined method with a delegated method; an | ||||
| 507 | exception will be thrown if you try. That is to say, if you define C<foo> in | ||||
| 508 | your class, you cannot override it with a delegated C<foo>. This is almost never | ||||
| 509 | something you would want to do, and if it is, you should do it by hand and not | ||||
| 510 | use Moose. | ||||
| 511 | |||||
| 512 | You cannot override any of the methods found in Moose::Object, or the C<BUILD> | ||||
| 513 | and C<DEMOLISH> methods. These will not throw an exception, but will silently | ||||
| 514 | move on to the next method in the list. My reasoning for this is that you would | ||||
| 515 | almost never want to do this, since it usually breaks your class. As with | ||||
| 516 | overriding locally defined methods, if you do want to do this, you should do it | ||||
| 517 | manually, not with Moose. | ||||
| 518 | |||||
| 519 | You do not I<need> to have a reader (or accessor) for the attribute in order | ||||
| 520 | to delegate to it. Moose will create a means of accessing the value for you, | ||||
| 521 | however this will be several times B<less> efficient then if you had given | ||||
| 522 | the attribute a reader (or accessor) to use. | ||||
| 523 | |||||
| 524 | Below is the documentation for each option format: | ||||
| 525 | |||||
| 526 | =over 4 | ||||
| 527 | |||||
| 528 | =item C<ARRAY> | ||||
| 529 | |||||
| 530 | This is the most common usage for I<handles>. You basically pass a list of | ||||
| 531 | method names to be delegated, and Moose will install a delegation method | ||||
| 532 | for each one. | ||||
| 533 | |||||
| 534 | =item C<HASH> | ||||
| 535 | |||||
| 536 | This is the second most common usage for I<handles>. Instead of a list of | ||||
| 537 | method names, you pass a HASH ref where each key is the method name you | ||||
| 538 | want installed locally, and its value is the name of the original method | ||||
| 539 | in the class being delegated to. | ||||
| 540 | |||||
| 541 | This can be very useful for recursive classes like trees. Here is a | ||||
| 542 | quick example (soon to be expanded into a Moose::Cookbook recipe): | ||||
| 543 | |||||
| 544 | package Tree; | ||||
| 545 | use Moose; | ||||
| 546 | |||||
| 547 | has 'node' => (is => 'rw', isa => 'Any'); | ||||
| 548 | |||||
| 549 | has 'children' => ( | ||||
| 550 | is => 'ro', | ||||
| 551 | isa => 'ArrayRef', | ||||
| 552 | default => sub { [] } | ||||
| 553 | ); | ||||
| 554 | |||||
| 555 | has 'parent' => ( | ||||
| 556 | is => 'rw', | ||||
| 557 | isa => 'Tree', | ||||
| 558 | weak_ref => 1, | ||||
| 559 | handles => { | ||||
| 560 | parent_node => 'node', | ||||
| 561 | siblings => 'children', | ||||
| 562 | } | ||||
| 563 | ); | ||||
| 564 | |||||
| 565 | In this example, the Tree package gets C<parent_node> and C<siblings> methods, | ||||
| 566 | which delegate to the C<node> and C<children> methods (respectively) of the Tree | ||||
| 567 | instance stored in the C<parent> slot. | ||||
| 568 | |||||
| 569 | You may also use an array reference to curry arguments to the original method. | ||||
| 570 | |||||
| 571 | has 'thing' => ( | ||||
| 572 | ... | ||||
| 573 | handles => { set_foo => [ set => 'foo' ] }, | ||||
| 574 | ); | ||||
| 575 | |||||
| 576 | # $self->set_foo(...) calls $self->thing->set('foo', ...) | ||||
| 577 | |||||
| 578 | The first element of the array reference is the original method name, and the | ||||
| 579 | rest is a list of curried arguments. | ||||
| 580 | |||||
| 581 | =item C<REGEXP> | ||||
| 582 | |||||
| 583 | The regexp option works very similar to the ARRAY option, except that it builds | ||||
| 584 | the list of methods for you. It starts by collecting all possible methods of the | ||||
| 585 | class being delegated to, then filters that list using the regexp supplied here. | ||||
| 586 | |||||
| 587 | B<NOTE:> An I<isa> option is required when using the regexp option format. This | ||||
| 588 | is so that we can determine (at compile time) the method list from the class. | ||||
| 589 | Without an I<isa> this is just not possible. | ||||
| 590 | |||||
| 591 | =item C<ROLE> or C<ROLETYPE> | ||||
| 592 | |||||
| 593 | With the role option, you specify the name of a role or a | ||||
| 594 | L<role type|Moose::Meta::TypeConstraint::Role> whose "interface" then becomes | ||||
| 595 | the list of methods to handle. The "interface" can be defined as; the methods | ||||
| 596 | of the role and any required methods of the role. It should be noted that this | ||||
| 597 | does B<not> include any method modifiers or generated attribute methods (which | ||||
| 598 | is consistent with role composition). | ||||
| 599 | |||||
| 600 | =item C<DUCKTYPE> | ||||
| 601 | |||||
| 602 | With the duck type option, you pass a duck type object whose "interface" then | ||||
| 603 | becomes the list of methods to handle. The "interface" can be defined as; the | ||||
| 604 | list of methods passed to C<duck_type> to create a duck type object. For more | ||||
| 605 | information on C<duck_type> please check | ||||
| 606 | L<Moose::Util::TypeConstraints>. | ||||
| 607 | |||||
| 608 | =item C<CODE> | ||||
| 609 | |||||
| 610 | This is the option to use when you really want to do something funky. You should | ||||
| 611 | only use it if you really know what you are doing, as it involves manual | ||||
| 612 | metaclass twiddling. | ||||
| 613 | |||||
| 614 | This takes a code reference, which should expect two arguments. The first is the | ||||
| 615 | attribute meta-object this I<handles> is attached to. The second is the | ||||
| 616 | metaclass of the class being delegated to. It expects you to return a hash (not | ||||
| 617 | a HASH ref) of the methods you want mapped. | ||||
| 618 | |||||
| 619 | =back | ||||
| 620 | |||||
| 621 | =item I<metaclass =E<gt> $metaclass_name> | ||||
| 622 | |||||
| 623 | This tells the class to use a custom attribute metaclass for this particular | ||||
| 624 | attribute. Custom attribute metaclasses are useful for extending the | ||||
| 625 | capabilities of the I<has> keyword: they are the simplest way to extend the MOP, | ||||
| 626 | but they are still a fairly advanced topic and too much to cover here, see | ||||
| 627 | L<Moose::Cookbook::Meta::Recipe1> for more information. | ||||
| 628 | |||||
| 629 | See L<Metaclass and Trait Name Resolution> for details on how a metaclass name | ||||
| 630 | is resolved to a class name. | ||||
| 631 | |||||
| 632 | =item I<traits =E<gt> [ @role_names ]> | ||||
| 633 | |||||
| 634 | This tells Moose to take the list of C<@role_names> and apply them to the | ||||
| 635 | attribute meta-object. This is very similar to the I<metaclass> option, but | ||||
| 636 | allows you to use more than one extension at a time. | ||||
| 637 | |||||
| 638 | See L<Metaclass and Trait Name Resolution> for details on how a trait name is | ||||
| 639 | resolved to a role name. | ||||
| 640 | |||||
| 641 | Also see L<Moose::Cookbook::Meta::Recipe3> for a metaclass trait | ||||
| 642 | example. | ||||
| 643 | |||||
| 644 | =item I<builder> => Str | ||||
| 645 | |||||
| 646 | The value of this key is the name of the method that will be called to | ||||
| 647 | obtain the value used to initialize the attribute. See the L<builder | ||||
| 648 | option docs in Class::MOP::Attribute|Class::MOP::Attribute/builder> | ||||
| 649 | and/or L<Moose::Cookbook::Basics::Recipe8> for more information. | ||||
| 650 | |||||
| 651 | =item I<default> => SCALAR | CODE | ||||
| 652 | |||||
| 653 | The value of this key is the default value which will initialize the attribute. | ||||
| 654 | |||||
| 655 | NOTE: If the value is a simple scalar (string or number), then it can | ||||
| 656 | be just passed as is. However, if you wish to initialize it with a | ||||
| 657 | HASH or ARRAY ref, then you need to wrap that inside a CODE reference. | ||||
| 658 | See the L<default option docs in | ||||
| 659 | Class::MOP::Attribute|Class::MOP::Attribute/default> for more | ||||
| 660 | information. | ||||
| 661 | |||||
| 662 | =item I<clearer> => Str | ||||
| 663 | |||||
| 664 | Creates a method allowing you to clear the value, see the L<clearer option | ||||
| 665 | docs in Class::MOP::Attribute|Class::MOP::Attribute/clearer> for more | ||||
| 666 | information. | ||||
| 667 | |||||
| 668 | =item I<predicate> => Str | ||||
| 669 | |||||
| 670 | Creates a method to perform a basic test to see if a value has been set in the | ||||
| 671 | attribute, see the L<predicate option docs in | ||||
| 672 | Class::MOP::Attribute|Class::MOP::Attribute/predicate> for more information. | ||||
| 673 | |||||
| 674 | =item I<lazy_build> => (0|1) | ||||

| 680 | |||||
| 681 | This may be a method name (referring to a method on the class with | ||||

| 698 | =item B<has +$name =E<gt> %options> | ||||
| 699 | |||||
| 700 | This is variation on the normal attribute creator C<has> which allows you to | ||||
| 701 | clone and extend an attribute from a superclass or from a role. Here is an | ||||
| 702 | example of the superclass usage: | ||||
| 703 | |||||
| 704 | package Foo; | ||||
| 705 | use Moose; | ||||
| 706 | |||||
| 707 | has 'message' => ( | ||||
| 708 | is => 'rw', | ||||
| 709 | isa => 'Str', | ||||
| 710 | default => 'Hello, I am a Foo' | ||||
| 711 | ); | ||||
| 712 | |||||
| 713 | package My::Foo; | ||||
| 714 | use Moose; | ||||
| 715 | |||||
| 716 | extends 'Foo'; | ||||
| 717 | |||||
| 718 | has '+message' => (default => 'Hello I am My::Foo'); | ||||
| 719 | |||||
| 720 | What is happening here is that B<My::Foo> is cloning the C<message> attribute | ||||
| 721 | from its parent class B<Foo>, retaining the C<is =E<gt> 'rw'> and C<isa =E<gt> | ||||
| 722 | 'Str'> characteristics, but changing the value in C<default>. | ||||
| 723 | |||||
| 724 | Here is another example, but within the context of a role: | ||||
| 725 | |||||
| 726 | package Foo::Role; | ||||
| 727 | use Moose::Role; | ||||
| 728 | |||||
| 729 | has 'message' => ( | ||||
| 730 | is => 'rw', | ||||
| 731 | isa => 'Str', | ||||
| 732 | default => 'Hello, I am a Foo' | ||||
| 733 | ); | ||||
| 734 | |||||
| 735 | package My::Foo; | ||||
| 736 | use Moose; | ||||
| 737 | |||||
| 738 | with 'Foo::Role'; | ||||
| 739 | |||||
| 740 | has '+message' => (default => 'Hello I am My::Foo'); | ||||
| 741 | |||||
| 742 | In this case, we are basically taking the attribute which the role supplied | ||||
| 743 | and altering it within the bounds of this feature. | ||||
| 744 | |||||
| 745 | Note that you can only extend an attribute from either a superclass or a role, | ||||
| 746 | you cannot extend an attribute in a role that composes over an attribute from | ||||
| 747 | another role. | ||||
| 748 | |||||
| 749 | Aside from where the attributes come from (one from superclass, the other | ||||
| 750 | from a role), this feature works exactly the same. This feature is restricted | ||||
| 751 | somewhat, so as to try and force at least I<some> sanity into it. You are only | ||||
| 752 | allowed to change the following attributes: | ||||
| 753 | |||||
| 754 | =over 4 | ||||
| 755 | |||||
| 756 | =item I<default> | ||||
| 757 | |||||
| 758 | Change the default value of an attribute. | ||||
| 759 | |||||
| 760 | =item I<coerce> | ||||
| 761 | |||||
| 762 | Change whether the attribute attempts to coerce a value passed to it. | ||||
| 763 | |||||
| 764 | =item I<required> | ||||
| 765 | |||||
| 766 | Change if the attribute is required to have a value. | ||||
| 767 | |||||
| 768 | =item I<documentation> | ||||
| 769 | |||||
| 770 | Change the documentation string associated with the attribute. | ||||
| 771 | |||||
| 772 | =item I<lazy> | ||||
| 773 | |||||
| 774 | Change if the attribute lazily initializes the slot. | ||||
| 775 | |||||
| 776 | =item I<isa> | ||||
| 777 | |||||
| 778 | You I<are> allowed to change the type without restriction. | ||||
| 779 | |||||
| 780 | It is recommended that you use this freedom with caution. We used to | ||||
| 781 | only allow for extension only if the type was a subtype of the parent's | ||||
| 782 | type, but we felt that was too restrictive and is better left as a | ||||
| 783 | policy decision. | ||||
| 784 | |||||
| 785 | =item I<handles> | ||||
| 786 | |||||
| 787 | You are allowed to B<add> a new C<handles> definition, but you are B<not> | ||||
| 788 | allowed to I<change> one. | ||||
| 789 | |||||
| 790 | =item I<builder> | ||||
| 791 | |||||
| 792 | You are allowed to B<add> a new C<builder> definition, but you are B<not> | ||||
| 793 | allowed to I<change> one. | ||||
| 794 | |||||
| 795 | =item I<metaclass> | ||||
| 796 | |||||
| 797 | You are allowed to B<add> a new C<metaclass> definition, but you are | ||||
| 798 | B<not> allowed to I<change> one. | ||||
| 799 | |||||
| 800 | =item I<traits> | ||||
| 801 | |||||
| 802 | You are allowed to B<add> additional traits to the C<traits> definition. | ||||
| 803 | These traits will be composed into the attribute, but preexisting traits | ||||
| 804 | B<are not> overridden, or removed. | ||||
| 805 | |||||
| 806 | =back | ||||
| 807 | |||||
| 808 | =item B<before $name|@names|\@names|qr/.../ =E<gt> sub { ... }> | ||||

| 810 | =item B<after $name|@names|\@names|qr/.../ =E<gt> sub { ... }> | ||||
| 811 | |||||
| 812 | =item B<around $name|@names|\@names|qr/.../ =E<gt> sub { ... }> | ||||
| 813 | |||||
| 814 | These three items are syntactic sugar for the before, after, and around method | ||||
| 815 | modifier features that L<Class::MOP> provides. More information on these may be | ||||
| 816 | found in L<Moose::Manual::MethodModifiers> and the | ||||
| 817 | L<Class::MOP::Class documentation|Class::MOP::Class/"Method Modifiers">. | ||||
| 818 | |||||
| 819 | =item B<super> | ||||
| 820 | |||||
| 821 | The keyword C<super> is a no-op when called outside of an C<override> method. In | ||||
| 822 | the context of an C<override> method, it will call the next most appropriate | ||||
| 823 | superclass method with the same arguments as the original method. | ||||
| 824 | |||||
| 825 | =item B<override ($name, &sub)> | ||||
| 826 | |||||
| 827 | An C<override> method is a way of explicitly saying "I am overriding this | ||||
| 828 | method from my superclass". You can call C<super> within this method, and | ||||
| 829 | it will work as expected. The same thing I<can> be accomplished with a normal | ||||
| 830 | method call and the C<SUPER::> pseudo-package; it is really your choice. | ||||
| 831 | |||||
| 832 | =item B<inner> | ||||
| 833 | |||||
| 834 | The keyword C<inner>, much like C<super>, is a no-op outside of the context of | ||||
| 835 | an C<augment> method. You can think of C<inner> as being the inverse of | ||||
| 836 | C<super>; the details of how C<inner> and C<augment> work is best described in | ||||
| 837 | the L<Moose::Cookbook::Basics::Recipe6>. | ||||
| 838 | |||||
| 839 | =item B<augment ($name, &sub)> | ||||
| 840 | |||||
| 841 | An C<augment> method, is a way of explicitly saying "I am augmenting this | ||||
| 842 | method from my superclass". Once again, the details of how C<inner> and | ||||
| 843 | C<augment> work is best described in the L<Moose::Cookbook::Basics::Recipe6>. | ||||
| 844 | |||||
| 845 | =item B<confess> | ||||
| 846 | |||||
| 847 | This is the C<Carp::confess> function, and exported here because I use it | ||||
| 848 | all the time. | ||||
| 849 | |||||
| 850 | =item B<blessed> | ||||
| 851 | |||||
| 852 | This is the C<Scalar::Util::blessed> function, it is exported here because I | ||||
| 853 | use it all the time. It is highly recommended that this is used instead of | ||||
| 854 | C<ref> anywhere you need to test for an object's class name. | ||||
| 855 | |||||
| 856 | =back | ||||
| 857 | |||||
| 858 | =head1 METACLASS | ||||
| 859 | |||||
| 860 | When you use Moose, you can specify which metaclass to use: | ||||
| 861 | |||||
| 862 | use Moose -metaclass => 'My::Meta::Class'; | ||||
| 863 | |||||
| 864 | You can also specify traits which will be applied to your metaclass: | ||||
| 865 | |||||
| 866 | use Moose -traits => 'My::Trait'; | ||||
| 867 | |||||
| 868 | This is very similar to the attribute traits feature. When you do | ||||
| 869 | this, your class's C<meta> object will have the specified traits | ||||
| 870 | applied to it. See L<Metaclass and Trait Name Resolution> for more | ||||
| 871 | details. | ||||
| 872 | |||||
| 873 | =head2 Metaclass and Trait Name Resolution | ||||
| 874 | |||||
| 875 | By default, when given a trait name, Moose simply tries to load a | ||||
| 876 | class of the same name. If such a class does not exist, it then looks | ||||
| 877 | for for a class matching | ||||
| 878 | B<Moose::Meta::$type::Custom::Trait::$trait_name>. The C<$type> | ||||
| 879 | variable here will be one of B<Attribute> or B<Class>, depending on | ||||
| 880 | what the trait is being applied to. | ||||
| 881 | |||||
| 882 | If a class with this long name exists, Moose checks to see if it has | ||||
| 883 | the method C<register_implementation>. This method is expected to | ||||
| 884 | return the I<real> class name of the trait. If there is no | ||||
| 885 | C<register_implementation> method, it will fall back to using | ||||
| 886 | B<Moose::Meta::$type::Custom::Trait::$trait> as the trait name. | ||||
| 887 | |||||
| 888 | The lookup method for metaclasses is the same, except that it looks | ||||
| 889 | for a class matching B<Moose::Meta::$type::Custom::$metaclass_name>. | ||||
| 890 | |||||
| 891 | If all this is confusing, take a look at | ||||
| 892 | L<Moose::Cookbook::Meta::Recipe3>, which demonstrates how to create an | ||||
| 893 | attribute trait. | ||||
| 894 | |||||
| 895 | =head1 UNIMPORTING FUNCTIONS | ||||
| 896 | |||||
| 897 | =head2 B<unimport> | ||||
| 898 | |||||
| 899 | Moose offers a way to remove the keywords it exports, through the C<unimport> | ||||
| 900 | method. You simply have to say C<no Moose> at the bottom of your code for this | ||||
| 901 | to work. Here is an example: | ||||
| 902 | |||||
| 903 | package Person; | ||||
| 904 | use Moose; | ||||
| 905 | |||||
| 906 | has 'first_name' => (is => 'rw', isa => 'Str'); | ||||
| 907 | has 'last_name' => (is => 'rw', isa => 'Str'); | ||||
| 908 | |||||
| 909 | sub full_name { | ||||
| 910 | my $self = shift; | ||||
| 911 | $self->first_name . ' ' . $self->last_name | ||||
| 912 | } | ||||
| 913 | |||||
| 914 | no Moose; # keywords are removed from the Person package | ||||
| 915 | |||||
| 916 | =head1 EXTENDING AND EMBEDDING MOOSE | ||||
| 917 | |||||
| 918 | To learn more about extending Moose, we recommend checking out the | ||||
| 919 | "Extending" recipes in the L<Moose::Cookbook>, starting with | ||||
| 920 | L<Moose::Cookbook::Extending::Recipe1>, which provides an overview of | ||||
| 921 | all the different ways you might extend Moose. | ||||
| 922 | |||||
| 923 | =head2 B<< Moose->init_meta(for_class => $class, base_class => $baseclass, metaclass => $metaclass) >> | ||||
| 924 | |||||
| 925 | The C<init_meta> method sets up the metaclass object for the class | ||||
| 926 | specified by C<for_class>. This method injects a a C<meta> accessor | ||||
| 927 | into the class so you can get at this object. It also sets the class's | ||||
| 928 | superclass to C<base_class>, with L<Moose::Object> as the default. | ||||
| 929 | |||||
| 930 | C<init_meta> returns the metaclass object for C<$class>. | ||||
| 931 | |||||
| 932 | You can specify an alternate metaclass with the C<metaclass> option. | ||||
| 933 | |||||
| 934 | For more detail on this topic, see L<Moose::Cookbook::Extending::Recipe2>. | ||||
| 935 | |||||
| 936 | This method used to be documented as a function which accepted | ||||
| 937 | positional parameters. This calling style will still work for | ||||
| 938 | backwards compatibility, but is deprecated. | ||||
| 939 | |||||
| 940 | =head2 B<import> | ||||
| 941 | |||||
| 942 | Moose's C<import> method supports the L<Sub::Exporter> form of C<{into =E<gt> $pkg}> | ||||
| 943 | and C<{into_level =E<gt> 1}>. | ||||
| 944 | |||||
| 945 | B<NOTE>: Doing this is more or less deprecated. Use L<Moose::Exporter> | ||||
| 946 | instead, which lets you stack multiple C<Moose.pm>-alike modules | ||||
| 947 | sanely. It handles getting the exported functions into the right place | ||||
| 948 | for you. | ||||
| 949 | |||||
| 950 | =head2 B<throw_error> | ||||
| 951 | |||||
| 952 | An alias for C<confess>, used by internally by Moose. | ||||
| 953 | |||||
| 954 | =head1 METACLASS COMPATIBILITY AND MOOSE | ||||
| 955 | |||||
| 956 | Metaclass compatibility is a thorny subject. You should start by | ||||
| 957 | reading the "About Metaclass compatibility" section in the | ||||
| 958 | C<Class::MOP> docs. | ||||
| 959 | |||||
| 960 | Moose will attempt to resolve a few cases of metaclass incompatibility | ||||
| 961 | when you set the superclasses for a class, unlike C<Class::MOP>, which | ||||
| 962 | simply dies if the metaclasses are incompatible. | ||||
| 963 | |||||
| 964 | In actuality, Moose fixes incompatibility for I<all> of a class's | ||||
| 965 | metaclasses, not just the class metaclass. That includes the instance | ||||
| 966 | metaclass, attribute metaclass, as well as its constructor class and | ||||
| 967 | destructor class. However, for simplicity this discussion will just | ||||
| 968 | refer to "metaclass", meaning the class metaclass, most of the time. | ||||
| 969 | |||||
| 970 | Moose has two algorithms for fixing metaclass incompatibility. | ||||
| 971 | |||||
| 972 | The first algorithm is very simple. If all the metaclass for the | ||||
| 973 | parent is a I<subclass> of the child's metaclass, then we simply | ||||
| 974 | replace the child's metaclass with the parent's. | ||||
| 975 | |||||
| 976 | The second algorithm is more complicated. It tries to determine if the | ||||
| 977 | metaclasses only "differ by roles". This means that the parent and | ||||
| 978 | child's metaclass share a common ancestor in their respective | ||||
| 979 | hierarchies, and that the subclasses under the common ancestor are | ||||
| 980 | only different because of role applications. This case is actually | ||||
| 981 | fairly common when you mix and match various C<MooseX::*> modules, | ||||
| 982 | many of which apply roles to the metaclass. | ||||
| 983 | |||||
| 984 | If the parent and child do differ by roles, Moose replaces the | ||||
| 985 | metaclass in the child with a newly created metaclass. This metaclass | ||||
| 986 | is a subclass of the parent's metaclass, does all of the roles that | ||||
| 987 | the child's metaclass did before being replaced. Effectively, this | ||||
| 988 | means the new metaclass does all of the roles done by both the | ||||
| 989 | parent's and child's original metaclasses. | ||||
| 990 | |||||
| 991 | Ultimately, this is all transparent to you except in the case of an | ||||
| 992 | unresolvable conflict. | ||||
| 993 | |||||
| 994 | =head2 The MooseX:: namespace | ||||
| 995 | |||||
| 996 | Generally if you're writing an extension I<for> Moose itself you'll want | ||||
| 997 | to put your extension in the C<MooseX::> namespace. This namespace is | ||||
| 998 | specifically for extensions that make Moose better or different in some | ||||
| 999 | fundamental way. It is traditionally B<not> for a package that just happens | ||||
| 1000 | to use Moose. This namespace follows from the examples of the C<LWPx::> | ||||
| 1001 | and C<DBIx::> namespaces that perform the same function for C<LWP> and C<DBI> | ||||
| 1002 | respectively. | ||||
| 1003 | |||||
| 1004 | =head1 CAVEATS | ||||
| 1005 | |||||
| 1006 | =over 4 | ||||
| 1007 | |||||
| 1008 | =item * | ||||
| 1009 | |||||
| 1010 | It should be noted that C<super> and C<inner> B<cannot> be used in the same | ||||
| 1011 | method. However, they may be combined within the same class hierarchy; see | ||||
| 1012 | F<t/014_override_augment_inner_super.t> for an example. | ||||
| 1013 | |||||
| 1014 | The reason for this is that C<super> is only valid within a method | ||||
| 1015 | with the C<override> modifier, and C<inner> will never be valid within an | ||||
| 1016 | C<override> method. In fact, C<augment> will skip over any C<override> methods | ||||
| 1017 | when searching for its appropriate C<inner>. | ||||
| 1018 | |||||
| 1019 | This might seem like a restriction, but I am of the opinion that keeping these | ||||
| 1020 | two features separate (yet interoperable) actually makes them easy to use, since | ||||
| 1021 | their behavior is then easier to predict. Time will tell whether I am right or | ||||
| 1022 | not (UPDATE: so far so good). | ||||

| 1106 | =head1 BUGS | ||||
| 1107 | |||||
| 1108 | All complex software has bugs lurking in it, and this module is no | ||||
| 1109 | exception. | ||||
| 1110 | |||||
| 1111 | Please report any bugs to C<bug-moose@rt.cpan.org>, or through the web | ||||
| 1112 | interface at L<http://rt.cpan.org>. | ||||
| 1113 | |||||
| 1114 | You can also discuss feature requests or possible bugs on the Moose mailing | ||||
| 1115 | list (moose@perl.org) or on IRC at L<irc://irc.perl.org/#moose>. | ||||
| 1116 | |||||
| 1117 | =head1 FEATURE REQUESTS | ||||
| 1118 | |||||
| 1119 | We are very strict about what features we add to the Moose core, especially | ||||
| 1120 | the user-visible features. Instead we have made sure that the underlying | ||||
| 1121 | meta-system of Moose is as extensible as possible so that you can add your | ||||
| 1122 | own features easily. | ||||
| 1123 | |||||
| 1124 | That said, occasionally there is a feature needed in the meta-system | ||||
| 1125 | to support your planned extension, in which case you should either | ||||
| 1126 | email the mailing list (moose@perl.org) or join us on IRC at | ||||
| 1127 | L<irc://irc.perl.org/#moose> to discuss. The | ||||
| 1128 | L<Moose::Manual::Contributing> has more detail about how and when you | ||||
| 1129 | can contribute. | ||||
| 1130 | |||||
| 1131 | =head1 AUTHOR | ||||
| 1132 | |||||
| 1133 | Moose is an open project, there are at this point dozens of people who have | ||||
| 1134 | contributed, and can contribute. If you have added anything to the Moose | ||||
| 1135 | project you have a commit bit on this file and can add your name to the list. | ||||
| 1136 | |||||
| 1137 | =head2 CABAL | ||||
| 1138 | |||||
| 1139 | However there are only a few people with the rights to release a new version | ||||
| 1140 | of Moose. The Moose Cabal are the people to go to with questions regarding | ||||
| 1141 | the wider purview of Moose, and help out maintaining not just the code | ||||
| 1142 | but the community as well. | ||||
