This UML diagram was made with Umbrello, and the source is in\nXMI in CVS.

I cannot stress enough the advantages of these changes:

\n\n
    \n
  1. the code is cleaner
    2. \n
  2. module dependencies are cleaner
    3. \n
  3. impossible to use methods outside the interface
    4. \n
  4. the algorithms are independent of the data classes
    5. \n
\n\n

The last advantage is really important: it allows alternative implementations of the data classes. For example, we could make debug\ndata classes, which, unlike the normal classes, do all sorts of checks when using methods of these classes. For example, they can\nexplicitely check that parameters are not null, of the right class, and generally make sense. This makes them, possibly, slower,\nbut also more type save, and as such great for debugging and development sessions.

\n\n

Another important application of making the CDK library independent of the data classes (and only depending on the\ninterfaces), is that we can have data classes\nshared with other Java libraries, such as JOElib, Octet,\nCML (Jumbo 5.0 is out!), and even proprietary libraries.\nThis approach is already used in the CDK-Taverna \nlibrary, and I anticipate much wider use with the arrival of Bioclipse.
