84 | Class::MOP::Method - Method Meta Object |
85 | |
8b978dd5 |
86 | =head1 DESCRIPTION |
87 | |
32202ce2 |
88 | The Method Protocol is very small, since methods in Perl 5 are just |
89 | subroutines within the particular package. We provide a very basic |
86482605 |
90 | introspection interface. |

100 | This will return a B<Class::MOP::Class> instance which is related |

110 | |
32202ce2 |
111 | This is the basic constructor, it returns a B<Class::MOP::Method> |
112 | instance which wraps the given C<$code> reference. You can also |
4c105333 |
113 | set the C<package_name> and C<name> attributes using the C<%params>. |
32202ce2 |
114 | If these are not set, then thier accessors will attempt to figure |
4c105333 |
115 | it out using the C<Class::MOP::get_code_info> function. |
116 | |
117 | =item B<clone (%params)> |
118 | |
32202ce2 |
119 | This will make a copy of the object, allowing you to override |
4c105333 |
120 | any values by stuffing them in C<%params>. |
