=head1 NAME 

Class::MOP::Method::Generated - Abstract base class for generated methods

=head1 DESCRIPTION

This is a C<Class::MOP::Method> subclass which is used interally 
by C<Class::MOP::Method::Accessor> and C<Class::MOP::Method::Constructor>.

=head1 METHODS

=over 4

=item B<new (%options)>

This creates the method based on the criteria in C<%options>, 
these options are:

=over 4

=item I<is_inline>

This is a boolean to indicate if the method should be generated
as a closure, or as a more optimized inline version.

=back

=item B<is_inline>

This returns the boolean which was passed into C<new>.

=item B<initialize_body>

This is an abstract method and will throw an exception if called.
