Re: UML class diagrams: hiding the attribute list

Not really. You can leave them off but the static model will be

incompleteness.

Ok, thanks... MagicDraw automatically draws an ellipse (...) if you press
DEL for a selected class method/attribute, but I didn't observe this
behaviour for other tools.

What you describe is done for Interface elements (the lollipop symbol)
on the Class Diagram. But an Interface is not a Class; it simple
provides a mapping of external messages to internal class operations.

Yes, you're right; I'm not using abstract interface constructs though, but
I'm "modelling" interfaces as a class (C++), and want to visualize the
interface structure for a not really computer scientific audience too.
So I'm just stereotyping the interface classes with <<interface>>, which is
quite self explaining.

Why would you want to omit class properties? Classes define object sets
and the only distinguishing aspect for set membership are the object
properties. Without a complete list of properties there is no way to
determine unambiguously which objects should belong to the set.

As Ilja wrote - I want to burn the details down to the core. It's for a
thesis, describing some software design; and it's not possible to fully
explain all details.

Does anybody know wether there's a formal obstacle to just 'hide' the
attribute list? Is this commonly accepted?

Thanks a lot,
Hinnerk
