92 | =head1 NAME | ||||
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 | |||||
107 | =over 4 | ||||
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). | ||||
