=head1 NAME
Moose::Meta::Method::Overridden - A Moose Method metaclass for overridden methods
=head1 VERSION
version 2.2207
=head1 DESCRIPTION
This class implements method overriding logic for the L<Moose>
C<override> keyword.
The overriding subroutine's parent will be invoked explicitly using
the C<super> keyword from the parent class's method definition.
=head1 METHODS
=head2 Moose::Meta::Method::Overridden->new(%options)
This constructs a new object. It accepts the following options:
=over 4
=item * class
The metaclass object for the class in which the override is being
declared. This option is required.
=item * name
The name of the method which we are overriding. This method must exist
in one of the class's superclasses. This option is required.
=item * method
The subroutine reference which implements the overriding. This option
is required.
=back
=head1 BUGS
See L<Moose/BUGS> for details on reporting bugs.
