56 | =head1 NAME | ||||
57 | |||||
58 | Moose::Meta::Method::Overridden - A Moose Method metaclass for overridden methods | ||||
59 | |||||
60 | =head1 DESCRIPTION | ||||
61 | |||||
62 | This class implements method overriding logic for the L<Moose> | ||||
63 | C<override> keyword. | ||||
64 | |||||
65 | The overriding subroutine's parent will be invoked explicitly using | ||||
66 | the C<super> keyword from the parent class's method definition. | ||||
67 | |||||
68 | =head1 METHODS | ||||
69 | |||||
70 | =over 4 | ||||
71 | |||||
72 | =item B<< Moose::Meta::Method::Overridden->new(%options) >> | ||||
73 | |||||
74 | This constructs a new object. It accepts the following options: | ||||
75 | |||||
76 | =over 8 | ||||
77 | |||||
78 | =item * class | ||||
79 | |||||
80 | The metaclass object for the class in which the override is being | ||||
81 | declared. This option is required. | ||||
82 | |||||
83 | =item * name | ||||
84 | |||||
85 | The name of the method which we are overriding. This method must exist | ||||
86 | in one of the class's superclasses. This option is required. | ||||
87 | |||||
88 | =item * method | ||||
89 | |||||
90 | The subroutine reference which implements the overriding. This option | ||||
91 | is required. | ||||
