Question

I’m just using StarUML to create my UML Class diagram and something is bothering me. I create an interface representation, which is a circle, however, there is no room to add which methods and attributes the interface defines. Is this normal UML practice?

If not, how do you know (say a class implements this interface and has 4 methods defined) which of the 4 methods came from the interface and which didnt?

Solved:

Ok just incase someone else has this problem- there are two notations, both are possible in StarUML but only one explicitly (the dot notation). To create the <> notation, enter the name as <> IInterface_Name and then draw a realisation line between the implementing classes. Be sure to manually delete the old (wrong) relationship you had by right clicking the class, collection editor and then relations.

It is very simple:

1. If you need just show method of interface – right click on interface and un-select Format/Suppress operation (see blue circle on picture)
2. If you need to display instead of circle just squared form of interface (on my picture it is ISome) use Format/Stereotype Display/Decoration (see red circle on picture bellow)
