| 1301 | Moose::Meta::Attribute - The Moose attribute metaclass | ||||
| 1302 | |||||

| 1305 | version 2.0602 | ||||
| 1306 | |||||
| 1307 | =head1 DESCRIPTION | ||||
| 1308 | |||||
| 1309 | This class is a subclass of L<Class::MOP::Attribute> that provides | ||||
| 1310 | additional Moose-specific functionality. | ||||
| 1311 | |||||
| 1312 | To really understand this class, you will need to start with the | ||||
| 1313 | L<Class::MOP::Attribute> documentation. This class can be understood | ||||
| 1314 | as a set of additional features on top of the basic feature provided | ||||
| 1315 | by that parent class. | ||||
| 1316 | |||||
| 1317 | =head1 INHERITANCE | ||||
| 1318 | |||||
| 1319 | C<Moose::Meta::Attribute> is a subclass of L<Class::MOP::Attribute>. | ||||
| 1320 | |||||
| 1321 | =head1 METHODS | ||||
| 1322 | |||||
| 1323 | Many of the documented below override methods in | ||||
| 1324 | L<Class::MOP::Attribute> and add Moose specific features. | ||||
| 1325 | |||||
| 1326 | =head2 Creation | ||||
| 1327 | |||||
| 1328 | =over 4 | ||||
| 1329 | |||||
| 1330 | =item B<< Moose::Meta::Attribute->new(%options) >> | ||||
| 1331 | |||||
| 1332 | This method overrides the L<Class::MOP::Attribute> constructor. | ||||
| 1333 | |||||
| 1334 | Many of the options below are described in more detail in the | ||||
| 1335 | L<Moose::Manual::Attributes> document. | ||||
| 1336 | |||||
| 1337 | It adds the following options to the constructor: | ||||
| 1338 | |||||
| 1339 | =over 8 | ||||
| 1340 | |||||
| 1341 | =item * is => 'ro', 'rw', 'bare' | ||||
| 1342 | |||||
| 1343 | This provides a shorthand for specifying the C<reader>, C<writer>, or | ||||
| 1344 | C<accessor> names. If the attribute is read-only ('ro') then it will | ||||
| 1345 | have a C<reader> method with the same attribute as the name. | ||||
| 1346 | |||||
| 1347 | If it is read-write ('rw') then it will have an C<accessor> method | ||||
| 1348 | with the same name. If you provide an explicit C<writer> for a | ||||
| 1349 | read-write attribute, then you will have a C<reader> with the same | ||||
| 1350 | name as the attribute, and a C<writer> with the name you provided. | ||||
| 1351 | |||||
| 1352 | Use 'bare' when you are deliberately not installing any methods | ||||
| 1353 | (accessor, reader, etc.) associated with this attribute; otherwise, | ||||
| 1354 | Moose will issue a deprecation warning when this attribute is added to a | ||||
| 1355 | metaclass. | ||||
| 1356 | |||||
| 1357 | =item * isa => $type | ||||
| 1358 | |||||
| 1359 | This option accepts a type. The type can be a string, which should be | ||||
| 1360 | a type name. If the type name is unknown, it is assumed to be a class | ||||
| 1361 | name. | ||||
| 1362 | |||||
| 1363 | This option can also accept a L<Moose::Meta::TypeConstraint> object. | ||||
| 1364 | |||||
| 1365 | If you I<also> provide a C<does> option, then your C<isa> option must | ||||
| 1366 | be a class name, and that class must do the role specified with | ||||
| 1367 | C<does>. | ||||
| 1368 | |||||
| 1369 | =item * does => $role | ||||
| 1370 | |||||
| 1371 | This is short-hand for saying that the attribute's type must be an | ||||
| 1372 | object which does the named role. | ||||
| 1373 | |||||
| 1374 | =item * coerce => $bool | ||||
| 1375 | |||||
| 1376 | This option is only valid for objects with a type constraint | ||||
| 1377 | (C<isa>) that defined a coercion. If this is true, then coercions will be applied whenever | ||||
| 1378 | this attribute is set. | ||||
| 1379 | |||||
| 1380 | You can make both this and the C<weak_ref> option true. | ||||
| 1381 | |||||
| 1382 | =item * trigger => $sub | ||||
| 1383 | |||||
| 1384 | This option accepts a subroutine reference, which will be called after | ||||
| 1385 | the attribute is set. | ||||
| 1386 | |||||
| 1387 | =item * required => $bool | ||||
| 1388 | |||||
| 1389 | An attribute which is required must be provided to the constructor. An | ||||
| 1390 | attribute which is required can also have a C<default> or C<builder>, | ||||
| 1391 | which will satisfy its required-ness. | ||||
| 1392 | |||||
| 1393 | A required attribute must have a C<default>, C<builder> or a | ||||
| 1394 | non-C<undef> C<init_arg> | ||||
| 1395 | |||||
| 1396 | =item * lazy => $bool | ||||
| 1397 | |||||
| 1398 | A lazy attribute must have a C<default> or C<builder>. When an | ||||
| 1399 | attribute is lazy, the default value will not be calculated until the | ||||
| 1400 | attribute is read. | ||||
| 1401 | |||||
| 1402 | =item * weak_ref => $bool | ||||
| 1403 | |||||
| 1404 | If this is true, the attribute's value will be stored as a weak | ||||
| 1405 | reference. | ||||
| 1406 | |||||
| 1407 | =item * auto_deref => $bool | ||||
| 1408 | |||||
| 1409 | If this is true, then the reader will dereference the value when it is | ||||
| 1410 | called. The attribute must have a type constraint which defines the | ||||
| 1411 | attribute as an array or hash reference. | ||||
| 1412 | |||||
| 1413 | =item * lazy_build => $bool | ||||
| 1414 | |||||
| 1415 | Setting this to true makes the attribute lazy and provides a number of | ||||
| 1416 | default methods. | ||||
| 1417 | |||||
| 1418 | has 'size' => ( | ||||
| 1419 | is => 'ro', | ||||
| 1420 | lazy_build => 1, | ||||
| 1421 | ); | ||||
| 1422 | |||||
| 1423 | is equivalent to this: | ||||

| 1451 | Note the doubled underscore in the builder name. Internally, Moose | ||||

| 1476 | =item B<< $attr->initialize_instance_slot($meta_instance, $instance, $params) >> | ||||
| 1477 | |||||
| 1478 | This method is used internally to initialize the attribute's slot in | ||||
| 1479 | the object C<$instance>. | ||||
| 1480 | |||||
| 1481 | This overrides the L<Class::MOP::Attribute> method to handle lazy | ||||
| 1482 | attributes, weak references, and type constraints. | ||||

| 1492 | |||||
| 1493 | I<Attribute (x) does not pass the type constraint (Int) with 'forty-two'> | ||||
| 1494 | |||||
| 1495 | Before setting the value, a check is made on the type constraint of | ||||
| 1496 | the attribute, if it has one, to see if the value passes it. If the | ||||
| 1497 | value fails to pass, the set operation dies. | ||||
| 1498 | |||||
| 1499 | Any coercion to convert values is done before checking the type constraint. | ||||
| 1500 | |||||
| 1501 | To check a value against a type constraint before setting it, fetch the | ||||
| 1502 | attribute instance using L<Class::MOP::Class/find_attribute_by_name>, | ||||
| 1503 | fetch the type_constraint from the attribute using L<Moose::Meta::Attribute/type_constraint> | ||||
| 1504 | and call L<Moose::Meta::TypeConstraint/check>. See L<Moose::Cookbook::Basics::Company_Subtypes> | ||||
| 1505 | for an example. | ||||

| 1514 | |||||
| 1515 | This method overrides the parent to also install delegation methods. | ||||
| 1516 | |||||
| 1517 | If, after installing all methods, the attribute object has no associated | ||||
| 1518 | methods, it throws an error unless C<< is => 'bare' >> was passed to the | ||||
| 1519 | attribute constructor. (Trying to add an attribute that has no associated | ||||
| 1520 | methods is almost always an error.) | ||||
| 1521 | |||||
| 1522 | =item B<< $attr->remove_accessors >> | ||||

| 1525 | |||||
| 1526 | =item B<< $attr->inline_set($instance_var, $value_var) >> | ||||
| 1527 | |||||
| 1528 | This method return a code snippet suitable for inlining the relevant | ||||
| 1529 | operation. It expect strings containing variable names to be used in the | ||||
| 1530 | inlining, like C<'$self'> or C<'$_[1]'>. | ||||
| 1531 | |||||
| 1532 | =item B<< $attr->install_delegation >> | ||||
| 1533 | |||||
| 1534 | This method adds its delegation methods to the attribute's associated | ||||
| 1535 | class, if it has any to add. | ||||
| 1536 | |||||
| 1537 | =item B<< $attr->remove_delegation >> | ||||
| 1538 | |||||
| 1539 | This method remove its delegation methods from the attribute's | ||||
| 1540 | associated class. | ||||
| 1541 | |||||
| 1542 | =item B<< $attr->accessor_metaclass >> | ||||

| 1546 | |||||
| 1547 | =item B<< $attr->delegation_metaclass >> | ||||

| 1561 | =item B<< $attr->does($role) >> | ||||
| 1562 | |||||
| 1563 | This indicates whether the I<attribute itself> does the given | ||||
| 1564 | role. The role can be given as a full class name, or as a resolvable | ||||
| 1565 | trait name. | ||||
| 1566 | |||||
| 1567 | Note that this checks the attribute itself, not its type constraint, | ||||
| 1568 | so it is checking the attribute's metaclass and any traits applied to | ||||
| 1569 | the attribute. | ||||
| 1570 | |||||
| 1571 | =item B<< Moose::Meta::Class->interpolate_class_and_new($name, %options) >> | ||||
| 1572 | |||||
| 1573 | This is an alternate constructor that handles the C<metaclass> and | ||||
| 1574 | C<traits> options. | ||||
| 1575 | |||||
| 1576 | Effectively, this method is a factory that finds or creates the | ||||
| 1577 | appropriate class for the given C<metaclass> and/or C<traits>. | ||||
| 1578 | |||||
| 1579 | Once it has the appropriate class, it will call C<< $class->new($name, | ||||
| 1580 | %options) >> on that class. | ||||
| 1581 | |||||
| 1582 | =item B<< $attr->clone_and_inherit_options(%options) >> | ||||
| 1583 | |||||
| 1584 | This method supports the C<has '+foo'> feature. It does various bits | ||||
| 1585 | of processing on the supplied C<%options> before ultimately calling | ||||
| 1586 | the C<clone> method. | ||||
| 1587 | |||||
| 1588 | One of its main tasks is to make sure that the C<%options> provided | ||||
| 1589 | does not include the options returned by the | ||||
| 1590 | C<illegal_options_for_inheritance> method. | ||||
| 1591 | |||||
| 1592 | =item B<< $attr->illegal_options_for_inheritance >> | ||||
| 1593 | |||||
| 1594 | This returns a blacklist of options that can not be overridden in a | ||||
| 1595 | subclass's attribute definition. | ||||
| 1596 | |||||
| 1597 | This exists to allow a custom metaclass to change or add to the list | ||||
| 1598 | of options which can not be changed. | ||||
| 1599 | |||||
| 1600 | =item B<< $attr->type_constraint >> | ||||
| 1601 | |||||
| 1602 | Returns the L<Moose::Meta::TypeConstraint> object for this attribute, | ||||
| 1603 | if it has one. | ||||
| 1604 | |||||
| 1605 | =item B<< $attr->has_type_constraint >> | ||||
| 1606 | |||||
| 1607 | Returns true if this attribute has a type constraint. | ||||
| 1608 | |||||
| 1609 | =item B<< $attr->verify_against_type_constraint($value) >> | ||||
| 1610 | |||||
| 1611 | Given a value, this method returns true if the value is valid for the | ||||
| 1612 | attribute's type constraint. If the value is not valid, it throws an | ||||
| 1613 | error. | ||||
| 1614 | |||||
| 1615 | =item B<< $attr->handles >> | ||||
| 1616 | |||||
| 1617 | This returns the value of the C<handles> option passed to the | ||||
| 1618 | constructor. | ||||
| 1619 | |||||
| 1620 | =item B<< $attr->has_handles >> | ||||

| 1633 | |||||
| 1634 | Returns true if this attribute is lazy. | ||||
| 1635 | |||||
| 1636 | =item B<< $attr->is_lazy_build >> | ||||
| 1637 | |||||
| 1638 | Returns true if the C<lazy_build> option was true when passed to the | ||||
| 1639 | constructor. | ||||
| 1640 | |||||
| 1641 | =item B<< $attr->should_coerce >> | ||||
| 1642 | |||||
| 1643 | Returns true if the C<coerce> option passed to the constructor was | ||||
| 1644 | true. | ||||
| 1645 | |||||
| 1646 | =item B<< $attr->should_auto_deref >> | ||||
| 1647 | |||||
| 1648 | Returns true if the C<auto_deref> option passed to the constructor was | ||||
| 1649 | true. | ||||
| 1650 | |||||
| 1651 | =item B<< $attr->trigger >> | ||||
| 1652 | |||||
| 1653 | This is the subroutine reference that was in the C<trigger> option | ||||
| 1654 | passed to the constructor, if any. | ||||
| 1655 | |||||
| 1656 | =item B<< $attr->has_trigger >> | ||||

| 1658 | Returns true if this attribute has a trigger set. | ||||

| 1669 | =item B<< $attr->applied_traits >> | ||||
| 1670 | |||||
| 1671 | This returns an array reference of all the traits which were applied | ||||
