61 | =head1 NAME | ||||
62 | |||||
63 | metaclass - a pragma for installing and using Class::MOP metaclasses | ||||
64 | |||||
65 | =head1 VERSION | ||||
66 | |||||
67 | version 2.0602 | ||||
68 | |||||
69 | =head1 SYNOPSIS | ||||
70 | |||||
71 | package MyClass; | ||||
72 | |||||
73 | # use Class::MOP::Class | ||||
74 | use metaclass; | ||||
75 | |||||
76 | # ... or use a custom metaclass | ||||
77 | use metaclass 'MyMetaClass'; | ||||
78 | |||||
79 | # ... or use a custom metaclass | ||||
80 | # and custom attribute and method | ||||
81 | # metaclasses | ||||
82 | use metaclass 'MyMetaClass' => ( | ||||
83 | 'attribute_metaclass' => 'MyAttributeMetaClass', | ||||
84 | 'method_metaclass' => 'MyMethodMetaClass', | ||||
85 | ); | ||||
86 | |||||
87 | # ... or just specify custom attribute | ||||
88 | # and method classes, and Class::MOP::Class | ||||
89 | # is the assumed metaclass | ||||
90 | use metaclass ( | ||||
91 | 'attribute_metaclass' => 'MyAttributeMetaClass', | ||||
92 | 'method_metaclass' => 'MyMethodMetaClass', | ||||
93 | ); | ||||
94 | |||||
95 | # if we'd rather not install a 'meta' method, we can do this | ||||
96 | use metaclass meta_name => undef; | ||||
97 | # or if we'd like it to have a different name, | ||||
98 | use metaclass meta_name => 'my_meta'; | ||||
99 | |||||
100 | =head1 DESCRIPTION | ||||
101 | |||||
102 | This is a pragma to make it easier to use a specific metaclass | ||||
103 | and a set of custom attribute and method metaclasses. It also | ||||
104 | installs a C<meta> method to your class as well, unless C<undef> | ||||
105 | is passed to the C<meta_name> option. | ||||
106 | |||||
107 | Note that if you are using Moose, you most likely do B<not> want | ||||
108 | to be using this - look into L<Moose::Util::MetaRole> instead. | ||||
109 | |||||
