+The specification of arguments is same as L<"register_hook"> method.

+The method is different from B<hook> and only a set of plugin and function are kept about one method.
+When specifying the method name which exists already, the old method is replaced with the new method.

+Only when C<$hook-E<gt>hookable_call_filter( 'register_method', $method, $action )> has returned truth,
