is it better to schedule methods on each object or on class Diagram itself?

[queirozfcom]

if all methods are in diagram the it would be a simple matter of each ing the methods and calling them at the end of diagram definition. if, on the other hand, the methods are scattered across a lot of nodes and edges, it might be a little more difficult to find them all and call them all?

Plus, it may be unnecessary to pass self as parameter to the methods as well.
