57
74862722 58Moose::Meta::Method::Overridden - A Moose Method metaclass for overridden methods
39b3bc94 59
60=head1 DESCRIPTION
61
cad6578d 62This class implements method overriding logic for the L<Moose>
63C<override> keyword.
18c2ec0e 64
cad6578d 65The overriding subroutine's parent will be invoked explicitly using
66the C<super> keyword from the parent class's method definition.
18c2ec0e 67
68=head1 METHODS
69
70=over 4
71
cad6578d 72=item B<< Moose::Meta::Method::Overridden->new(%options) >>
73
74This constructs a new object. It accepts the following options:
75
76=over 8
77
78=item * class
79
80The metaclass object for the class in which the override is being
81declared. This option is required.
82
83=item * name
84
85The name of the method which we are overriding. This method must exist
86in one of the class's superclasses. This option is required.
87
88=item * method
89
90The subroutine reference which implements the overriding. This option
91is required.
