86 | =head1 NAME | |||
87 | ||||
88 | Class::MOP::Method::Meta - Method Meta Object for C<meta> methods | |||
89 | ||||
90 | =head1 DESCRIPTION | |||
91 | ||||
92 | This is a L<Class::MOP::Method> subclass which represents C<meta> | |||
93 | methods installed into classes by Class::MOP. | |||
94 | ||||
95 | =head1 METHODS | |||
96 | ||||
97 | =over 4 | |||
98 | ||||
99 | =item B<< Class::MOP::Method::Wrapped->wrap($metamethod, %options) >> | |||
100 | ||||
101 | This is the constructor. It accepts a L<Class::MOP::Method> object and | |||
102 | a hash of options. The options accepted are identical to the ones | |||
103 | accepted by L<Class::MOP::Method>, except that C<body> cannot be passed | |||
104 | (it will be generated automatically). | |||
