60 | =head1 NAME | ||||
61 | |||||
62 | Moose::Meta::Method::Overridden - A Moose Method metaclass for overridden methods | ||||
63 | |||||
64 | =head1 VERSION | ||||
65 | |||||
66 | version 2.0602 | ||||
67 | |||||
68 | =head1 DESCRIPTION | ||||
69 | |||||
70 | This class implements method overriding logic for the L<Moose> | ||||
71 | C<override> keyword. | ||||
72 | |||||
73 | The overriding subroutine's parent will be invoked explicitly using | ||||
74 | the C<super> keyword from the parent class's method definition. | ||||
75 | |||||
76 | =head1 METHODS | ||||
77 | |||||
78 | =over 4 | ||||
79 | |||||
80 | =item B<< Moose::Meta::Method::Overridden->new(%options) >> | ||||
81 | |||||
82 | This constructs a new object. It accepts the following options: | ||||
83 | |||||
84 | =over 8 | ||||
85 | |||||
86 | =item * class | ||||
87 | |||||
88 | The metaclass object for the class in which the override is being | ||||
89 | declared. This option is required. | ||||
90 | |||||
91 | =item * name | ||||
92 | |||||
93 | The name of the method which we are overriding. This method must exist | ||||
94 | in one of the class's superclasses. This option is required. | ||||
95 | |||||
96 | =item * method | ||||
97 | |||||
98 | The subroutine reference which implements the overriding. This option | ||||
99 | is required. | ||||
