Ok, then it is not in the your DataSource class there is a need for
the calculate method, but in your generic filesystem class, to which
the DataSource refers to (through configuration).
As I understand, CakePHP use a DataSource to provide an implementation
independent interface to the DboSource (plus subclasses)
implementation dependent interface.
Thus your FilewidSource class (the implementation dependent interface)
should provide the calculate method.
Am I correct in my understanding of your issue?
Enjoy ;)
