# ABSTRACT: A Moose Method metaclass for overridden methods

=head1 NAME

Moose::Meta::Method::Overridden - A Moose Method metaclass for overridden methods

=head1 VERSION

version 2.0604

=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

=over 4

=item B<< Moose::Meta::Method::Overridden->new(%options) >>

This constructs a new object. It accepts the following options:

=over 8

=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.
