=head1 NAME

Moose::Meta::Method::Augmented - A Moose Method metaclass for augmented methods

=head1 VERSION

version 2.1806

=head1 DESCRIPTION

This class implements method augmentation logic for the L<Moose>
C<augment> keyword.

The augmentation subroutine reference will be invoked explicitly using
the C<inner> keyword from the parent class's method definition.

=head1 INHERITANCE

C<Moose::Meta::Method::Augmented> is a subclass of L<Moose::Meta::Method>.

=head1 METHODS

=head2 Moose::Meta::Method::Augmented->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 augmentation is being
declared. This option is required.

=item * name

The name of the method which we are augmenting. This method must exist
in one of the class's superclasses. This option is required.

=item * method

The subroutine reference which implements the augmentation. This
option is required.
