18 | This module contains some Mixin classes for the db objects. | |
19 | ||
20 | A bunch of functions on the db objects are really more like | |
21 | "utility functions": They could live outside the classes | |
22 | and be called "by hand" passing the appropiate reference. | |
23 | They usually only use the public API of the object and | |
24 | rarely use database related stuff. | |
25 | ||
26 | These functions now live here and get "mixed in" into the | |
27 | real objects. | |
