+=item B<subclasses>
+
+This returns a list of subclasses for this class.
=back
=item B<get_method_map>
+Returns a HASH ref of name to CODE reference mapping for this class.
+
=item B<method_metaclass>
+Returns the class name of the method metaclass, see L<Class::MOP::Method>
+for more information on the method metaclasses.
+
=item B<add_method ($method_name, $method)>
This will take a C<$method_name> and CODE reference to that
The Class::MOP::Method is codifiable, so you can use it like a normal
CODE reference, see L<Class::MOP::Method> for more information.
-=item B<find_method_by_name ($method_name>
+=item B<find_method_by_name ($method_name)>
This will return a CODE reference of the specified C<$method_name>,
or return undef if that method does not exist.
=item B<attribute_metaclass>
+Returns the class name of the attribute metaclass, see L<Class::MOP::Attribute>
+for more information on the attribute metaclasses.
+
=item B<get_attribute_map>
-=item B<add_attribute ($attribute_meta_object | $attribute_name, %attribute_spec)>
+This returns a HASH ref of name to attribute meta-object mapping.
+
+=item B<add_attribute ($attribute_meta_object | ($attribute_name, %attribute_spec))>
This stores the C<$attribute_meta_object> (or creates one from the
C<$attribute_name> and C<%attribute_spec>) in the B<Class::MOP::Class>
This method will reverse tranforamtion upon the class which
made it immutable.
+=item B<get_immutable_transformer>
+
+Return a transformer suitable for making this class immutable or, if this
+class is immutable, the transformer used to make it immutable.
+
+=item B<get_immutable_options>
+
+If the class is immutable, return the options used to make it immutable.
+
=item B<create_immutable_transformer>
Create a transformer suitable for making this class immutable
