Re: UML class diagrams: hiding the attribute list

Responding to Preuß...

Why would you want to omit class properties?


Why would you show all class properties if they aren't important for the point you want to communicate?

The diagram is part of an OOA or OOD model that specifies the solution to the problem at a given level of abstraction. That specification should be precise, unambiguous, and complete relative to OOA/D abstraction. So if the property isn't relevant to the solution it shouldn't be in the model.

What you say would be true for throw-away models that were used for pure communication peripherally to development. But then one would simply not include the properties and would not worry, as the OP did, about how to indicate unspecified properties.
