Critics concerning interfaces and subclasses.
It is not clear why this category has the name
The current version of ArgoUML has three critics in this
Operations in Interfaces must be public
Suggestion that there is no point in having non-public
operations in Interfaces, since they must be visible to be
realized by a class.
Interfaces may only have operations
Suggestion that an interfaces has attributes defined.
The UML standard defines interfaces to have operations.
ArgoUML does not allow you to add attributes to
interfaces, so this should never occur in the ArgoUML
model. It might trigger if a project has been loaded with
XMI created by another tool.
Remove Reference to Specific Subclass
Suggestion that in a good design, a class should not
reference its subclasses directly through attributes,
operations or associations.
