104 Class::MOP::Method::Generated - Abstract base class for generated methods
108 This is a C<Class::MOP::Method> subclass which is used interally
109 by C<Class::MOP::Method::Accessor> and C<Class::MOP::Method::Constructor>.
115 =item B<new (%options)>
117 This creates the method based on the criteria in C<%options>,
124 This is a boolean to indicate if the method should be generated
125 as a closure, or as a more optimized inline version.
131 This returns the boolean which was passed into C<new>.
133 =item B<initialize_body>
135 This is an abstract method and will throw an exception if called.
