caches them for the duration of the current request (see
L<SL::Request/cache>).
+If you know in advance that you will likely need all objects of a
+particular type then you can pre-cache them by calling the manager's
+C<cache_all> function. For example, if you expect to need all unit
+objects, you can use C<SL::DB::Manager::Unit-E<gt>cache_all> before
+you start the actual work. Later you can use
+C<SL::DB::Unit-E<gt>load_cached> to retrieve individual objects and be
+sure that they're already cached.
+
This method can be called both as an instance method and a class
method. It loads objects for the corresponding class (e.g. both
C<SL::DB::Part-E<gt>load_cached(…)> and
Returns the object/class it was called on.
+=item C<clone_and_reset>
+
+This works similar to L<Rose::DB::Object::Helpers/clone_and_reset>: it
+returns a cloned instance of C<$self>. All primary and unique key
+fields have been reset.
+
+The difference between Rose's and this function is that this function
+will also skip setting the following fields if such columns exist for
+C<$self>: C<itime>, C<mtime>.
+
+=item C<presenter>
+
+Returns a proxy wrapper that will dispatch all method calls to the presenter
+with the same name as the class of the involking object.
+
+For the full documentation about its capabilites see
+L<SL::DB::Helper::Presenter>
+
+=item C<as_debug_info>
+
+Returns a hash containing solely the essentials for dumping it with
+L<LXDebug/dump>. The returned hash consists of the column names with
+associated column values in stringified form.
