| 93 | |||||
| 94 | Class::MOP::Method::Meta - Method Meta Object for C<meta> methods | ||||
| 95 | |||||
| 96 | =head1 VERSION | ||||
| 97 | |||||
| 98 | version 2.0602 | ||||
| 99 | |||||
| 100 | =head1 DESCRIPTION | ||||
| 101 | |||||
| 102 | This is a L<Class::MOP::Method> subclass which represents C<meta> | ||||
| 103 | methods installed into classes by Class::MOP. | ||||
| 104 | |||||
| 105 | =head1 METHODS | ||||
| 106 | |||||

| 108 | |||||
| 109 | =item B<< Class::MOP::Method::Wrapped->wrap($metamethod, %options) >> | ||||
| 110 | |||||
| 111 | This is the constructor. It accepts a L<Class::MOP::Method> object and | ||||
| 112 | a hash of options. The options accepted are identical to the ones | ||||
| 113 | accepted by L<Class::MOP::Method>, except that C<body> cannot be passed | ||||
| 114 | (it will be generated automatically). | ||||
