| 1543 | ); | ||||
| 1544 | |||||
| 1545 | =head1 DESCRIPTION | ||||
| 1546 | |||||
| 1547 | The Class Protocol is the largest and most complex part of the | ||||
| 1548 | Class::MOP meta-object protocol. It controls the introspection and | ||||
| 1549 | manipulation of Perl 5 classes, and it can create them as well. The | ||||
| 1550 | best way to understand what this module can do is to read the | ||||
| 1551 | documentation for each of its methods. | ||||
| 1552 | |||||
| 1553 | =head1 INHERITANCE | ||||
| 1554 | |||||
| 1555 | C<Class::MOP::Class> is a subclass of L<Class::MOP::Module>. | ||||
| 1556 | |||||
| 1557 | =head1 METHODS | ||||
| 1558 | |||||
| 1559 | =head2 Class construction | ||||
| 1560 | |||||
| 1561 | These methods all create new C<Class::MOP::Class> objects. These | ||||
| 1562 | objects can represent existing classes or they can be used to create | ||||
| 1563 | new classes from scratch. | ||||
| 1564 | |||||
| 1565 | The metaclass object for a given class is a singleton. If you attempt | ||||
| 1566 | to create a metaclass for the same class twice, you will just get the | ||||
| 1567 | existing object. | ||||
| 1568 | |||||
| 1569 | =over 4 | ||||
| 1570 | |||||
| 1571 | =item B<< Class::MOP::Class->create($package_name, %options) >> | ||||
| 1572 | |||||
| 1573 | This method creates a new C<Class::MOP::Class> object with the given | ||||
| 1574 | package name. It accepts a number of options: | ||||
| 1575 | |||||
| 1576 | =over 8 | ||||
| 1577 | |||||
| 1578 | =item * version | ||||
| 1579 | |||||
| 1580 | An optional version number for the newly created package. | ||||
| 1581 | |||||
| 1582 | =item * authority | ||||
| 1583 | |||||
| 1584 | An optional authority for the newly created package. | ||||
| 1585 | |||||
| 1586 | =item * superclasses | ||||
| 1587 | |||||
| 1588 | An optional array reference of superclass names. | ||||
| 1589 | |||||
| 1590 | =item * methods | ||||
| 1591 | |||||
| 1592 | An optional hash reference of methods for the class. The keys of the | ||||
| 1593 | hash reference are method names and values are subroutine references. | ||||
| 1594 | |||||
| 1595 | =item * attributes | ||||
| 1596 | |||||
| 1597 | An optional array reference of L<Class::MOP::Attribute> objects. | ||||
| 1598 | |||||
| 1599 | =item * meta_name | ||||
| 1600 | |||||
| 1601 | Specifies the name to install the C<meta> method for this class under. | ||||
| 1602 | If it is not passed, C<meta> is assumed, and if C<undef> is explicitly | ||||
| 1603 | given, no meta method will be installed. | ||||
| 1604 | |||||
| 1605 | =item * weaken | ||||
| 1606 | |||||
| 1607 | If true, the metaclass that is stored in the global cache will be a | ||||
| 1608 | weak reference. | ||||
| 1609 | |||||
| 1610 | Classes created in this way are destroyed once the metaclass they are | ||||
| 1611 | attached to goes out of scope, and will be removed from Perl's internal | ||||
| 1612 | symbol table. | ||||
| 1613 | |||||
| 1614 | All instances of a class with a weakened metaclass keep a special | ||||
| 1615 | reference to the metaclass object, which prevents the metaclass from | ||||
| 1616 | going out of scope while any instances exist. | ||||
| 1617 | |||||
| 1618 | This only works if the instance is based on a hash reference, however. | ||||
| 1619 | |||||
| 1620 | =back | ||||
| 1621 | |||||
| 1622 | =item B<< Class::MOP::Class->create_anon_class(%options) >> | ||||
| 1623 | |||||
| 1624 | This method works just like C<< Class::MOP::Class->create >> but it | ||||
| 1625 | creates an "anonymous" class. In fact, the class does have a name, but | ||||
| 1626 | that name is a unique name generated internally by this module. | ||||
| 1627 | |||||
| 1628 | It accepts the same C<superclasses>, C<methods>, and C<attributes> | ||||
| 1629 | parameters that C<create> accepts. | ||||
| 1630 | |||||
| 1631 | Anonymous classes default to C<< weaken => 1 >>, although this can be | ||||
| 1632 | overridden. | ||||
| 1633 | |||||
| 1634 | =item B<< Class::MOP::Class->initialize($package_name, %options) >> | ||||
| 1635 | |||||
| 1636 | This method will initialize a C<Class::MOP::Class> object for the | ||||
| 1637 | named package. Unlike C<create>, this method I<will not> create a new | ||||
| 1638 | class. | ||||
| 1639 | |||||
| 1640 | The purpose of this method is to retrieve a C<Class::MOP::Class> | ||||
| 1641 | object for introspecting an existing class. | ||||
| 1642 | |||||
| 1643 | If an existing C<Class::MOP::Class> object exists for the named | ||||
| 1644 | package, it will be returned, and any options provided will be | ||||
| 1645 | ignored! | ||||
| 1646 | |||||
| 1647 | If the object does not yet exist, it will be created. | ||||
| 1648 | |||||
| 1649 | The valid options that can be passed to this method are | ||||
| 1650 | C<attribute_metaclass>, C<method_metaclass>, | ||||
| 1651 | C<wrapped_method_metaclass>, and C<instance_metaclass>. These are all | ||||
| 1652 | optional, and default to the appropriate class in the C<Class::MOP> | ||||
| 1653 | distribution. | ||||
| 1654 | |||||
| 1655 | =back | ||||
| 1656 | |||||
| 1657 | =head2 Object instance construction and cloning | ||||
| 1658 | |||||
| 1659 | These methods are all related to creating and/or cloning object | ||||
| 1660 | instances. | ||||
| 1661 | |||||
| 1662 | =over 4 | ||||
| 1663 | |||||
| 1664 | =item B<< $metaclass->clone_object($instance, %params) >> | ||||
| 1665 | |||||
| 1666 | This method clones an existing object instance. Any parameters you | ||||
| 1667 | provide are will override existing attribute values in the object. | ||||
| 1668 | |||||
| 1669 | This is a convenience method for cloning an object instance, then | ||||
| 1670 | blessing it into the appropriate package. | ||||
| 1671 | |||||
| 1672 | You could implement a clone method in your class, using this method: | ||||
| 1673 | |||||
| 1674 | sub clone { | ||||
| 1675 | my ($self, %params) = @_; | ||||
| 1676 | $self->meta->clone_object($self, %params); | ||||
| 1677 | } | ||||
| 1678 | |||||
| 1679 | =item B<< $metaclass->rebless_instance($instance, %params) >> | ||||
| 1680 | |||||
| 1681 | This method changes the class of C<$instance> to the metaclass's class. | ||||
| 1682 | |||||
| 1683 | You can only rebless an instance into a subclass of its current | ||||
| 1684 | class. If you pass any additional parameters, these will be treated | ||||
| 1685 | like constructor parameters and used to initialize the object's | ||||
| 1686 | attributes. Any existing attributes that are already set will be | ||||
| 1687 | overwritten. | ||||
| 1688 | |||||
| 1689 | Before reblessing the instance, this method will call | ||||
| 1690 | C<rebless_instance_away> on the instance's current metaclass. This method | ||||
| 1691 | will be passed the instance, the new metaclass, and any parameters | ||||
| 1692 | specified to C<rebless_instance>. By default, C<rebless_instance_away> | ||||
| 1693 | does nothing; it is merely a hook. | ||||
| 1694 | |||||
| 1695 | =item B<< $metaclass->rebless_instance_back($instance) >> | ||||
| 1696 | |||||
| 1697 | Does the same thing as C<rebless_instance>, except that you can only | ||||
| 1698 | rebless an instance into one of its superclasses. Any attributes that | ||||
| 1699 | do not exist in the superclass will be deinitialized. | ||||
| 1700 | |||||
| 1701 | This is a much more dangerous operation than C<rebless_instance>, | ||||
| 1702 | especially when multiple inheritance is involved, so use this carefully! | ||||
| 1703 | |||||
| 1704 | =item B<< $metaclass->new_object(%params) >> | ||||
| 1705 | |||||
| 1706 | This method is used to create a new object of the metaclass's | ||||
| 1707 | class. Any parameters you provide are used to initialize the | ||||
| 1708 | instance's attributes. A special C<__INSTANCE__> key can be passed to | ||||
| 1709 | provide an already generated instance, rather than having Class::MOP | ||||
| 1710 | generate it for you. This is mostly useful for using Class::MOP with | ||||
| 1711 | foreign classes which generate instances using their own constructors. | ||||
| 1712 | |||||
| 1713 | =item B<< $metaclass->instance_metaclass >> | ||||
| 1714 | |||||
| 1715 | Returns the class name of the instance metaclass. See | ||||
| 1716 | L<Class::MOP::Instance> for more information on the instance | ||||

| 1794 | Methods defined outside the package with a fully qualified name (C<sub | ||||
| 1795 | Package::name { ... }>) will be included. Similarly, methods named | ||||
| 1796 | with a fully qualified name using L<Sub::Name> are also included. | ||||
| 1797 | |||||

| 1801 | method in a class, and these heuristics may get the wrong answer in | ||||
| 1802 | some edge cases. However, for most "normal" cases the heuristics work | ||||

| 1825 | |||||
| 1826 | This method takes a method name and a subroutine reference, and adds | ||||
| 1827 | the method to the class. | ||||
| 1828 | |||||
| 1829 | The subroutine reference can be a L<Class::MOP::Method>, and you are | ||||
| 1830 | strongly encouraged to pass a meta method object instead of a code | ||||
| 1831 | reference. If you do so, that object gets stored as part of the | ||||
| 1832 | class's method map directly. If not, the meta information will have to | ||||
| 1833 | be recreated later, and may be incorrect. | ||||
| 1834 | |||||
| 1835 | If you provide a method object, this method will clone that object if | ||||
| 1836 | the object's package name does not match the class name. This lets us | ||||
| 1837 | track the original source of any methods added from other classes | ||||
| 1838 | (notably Moose roles). | ||||

| 1879 | tree, so it returns a list of methods. | ||||
| 1880 | |||||
| 1881 | Each method is returned as a hash reference with three keys. The keys | ||||
| 1882 | are C<name>, C<class>, and C<code>. The C<code> key has a | ||||
| 1883 | L<Class::MOP::Method> object as its value. | ||||

| 2014 | |||||
| 2015 | Making a class immutable "freezes" the class definition. You can no | ||||
| 2016 | longer call methods which alter the class, such as adding or removing | ||||
| 2017 | methods or attributes. | ||||
| 2018 | |||||
| 2019 | Making a class immutable lets us optimize the class by inlining some | ||||
| 2020 | methods, and also allows us to optimize some methods on the metaclass | ||||
| 2021 | object itself. | ||||
| 2022 | |||||
| 2023 | After immutabilization, the metaclass object will cache most informational | ||||
| 2024 | methods that returns information about methods or attributes. Methods which | ||||
| 2025 | would alter the class, such as C<add_attribute> and C<add_method>, will | ||||
| 2026 | throw an error on an immutable metaclass object. | ||||
| 2027 | |||||

| 2105 | =head2 Method Modifiers | ||||
| 2106 | |||||
| 2107 | Method modifiers are hooks which allow a method to be wrapped with | ||||
| 2108 | I<before>, I<after> and I<around> method modifiers. Every time a | ||||
| 2109 | method is called, its modifiers are also called. | ||||
| 2110 | |||||
| 2111 | A class can modify its own methods, as well as methods defined in | ||||
| 2112 | parent classes. | ||||
| 2113 | |||||
| 2114 | =head3 How method modifiers work? | ||||
| 2115 | |||||
| 2116 | Method modifiers work by wrapping the original method and then | ||||
| 2117 | replacing it in the class's symbol table. The wrappers will handle | ||||
| 2118 | calling all the modifiers in the appropriate order and preserving the | ||||
| 2119 | calling context for the original method. | ||||
| 2120 | |||||
| 2121 | The return values of C<before> and C<after> modifiers are | ||||
| 2122 | ignored. This is because their purpose is B<not> to filter the input | ||||
| 2123 | and output of the primary method (this is done with an I<around> | ||||
| 2124 | modifier). | ||||
| 2125 | |||||
| 2126 | This may seem like an odd restriction to some, but doing this allows | ||||
| 2127 | for simple code to be added at the beginning or end of a method call | ||||
| 2128 | without altering the function of the wrapped method or placing any | ||||
| 2129 | extra responsibility on the code of the modifier. | ||||
| 2130 | |||||
| 2131 | Of course if you have more complex needs, you can use the C<around> | ||||
| 2132 | modifier which allows you to change both the parameters passed to the | ||||
| 2133 | wrapped method, as well as its return value. | ||||
| 2134 | |||||
| 2135 | Before and around modifiers are called in last-defined-first-called | ||||
| 2136 | order, while after modifiers are called in first-defined-first-called | ||||
| 2137 | order. So the call tree might looks something like this: | ||||
| 2138 | |||||
| 2139 | before 2 | ||||
| 2140 | before 1 | ||||
| 2141 | around 2 | ||||
| 2142 | around 1 | ||||
| 2143 | primary | ||||
| 2144 | around 1 | ||||
| 2145 | around 2 | ||||
| 2146 | after 1 | ||||
| 2147 | after 2 | ||||
| 2148 | |||||
| 2149 | =head3 What is the performance impact? | ||||

| 2151 | Of course there is a performance cost associated with method | ||||
| 2152 | modifiers, but we have made every effort to make that cost directly | ||||
| 2153 | proportional to the number of modifier features you use. | ||||
| 2154 | |||||
| 2155 | The wrapping method does its best to B<only> do as much work as it | ||||
| 2156 | absolutely needs to. In order to do this we have moved some of the | ||||
| 2157 | performance costs to set-up time, where they are easier to amortize. | ||||
| 2158 | |||||
| 2159 | All this said, our benchmarks have indicated the following: | ||||
| 2160 | |||||
| 2161 | simple wrapper with no modifiers 100% slower | ||||
| 2162 | simple wrapper with simple before modifier 400% slower | ||||
| 2163 | simple wrapper with simple after modifier 450% slower | ||||
| 2164 | simple wrapper with simple around modifier 500-550% slower | ||||
| 2165 | simple wrapper with all 3 modifiers 1100% slower | ||||
| 2166 | |||||
| 2167 | These numbers may seem daunting, but you must remember, every feature | ||||
| 2168 | comes with some cost. To put things in perspective, just doing a | ||||
| 2169 | simple C<AUTOLOAD> which does nothing but extract the name of the | ||||
| 2170 | method called and return it costs about 400% over a normal method | ||||
| 2171 | call. | ||||

| 2177 | This wraps the specified method with the supplied subroutine | ||||
| 2178 | reference. The modifier will be called as a method itself, and will | ||||
| 2179 | receive the same arguments as are passed to the method. | ||||
| 2180 | |||||
| 2181 | When the modifier exits, the wrapped method will be called. | ||||
| 2182 | |||||
| 2183 | The return value of the modifier will be ignored. | ||||

| 2197 | This wraps the specified method with the supplied subroutine | ||||
| 2198 | reference. | ||||
| 2199 | |||||
| 2200 | The first argument passed to the modifier will be a subroutine | ||||
| 2201 | reference to the wrapped method. The second argument is the object, | ||||
| 2202 | and after that come any arguments passed when the method is called. | ||||
| 2203 | |||||
| 2204 | The around modifier can choose to call the original method, as well as | ||||
| 2205 | what arguments to pass if it does so. | ||||
| 2206 | |||||
| 2207 | The return value of the modifier is what will be seen by the caller. | ||||
