56 | |
ecb59493 |
57 | Moose::Meta::Method::Overriden - A Moose Method metaclass for overriden methods |
39b3bc94 |
58 | |
59 | =head1 DESCRIPTION |
60 | |
18c2ec0e |
61 | This class implements method overriding logic for the L<Moose> C<override> keyword. |
62 | |
63 | This involves setting up C<super> for the overriding body, and dispatching to |
64 | the correct parent method upon its invocation. |
