Class diagram class attribute: list

[ecsgz]

Hello,

how can I add a list of enums or other class references as an attribute of a class? Example:

--------------
ClassA
--------------
- listofElements: List<ClassB>
--------------

Thank you for the help!

Not sure which language that is, but generally you set the multiplicity for attributes to anything other than [1].

Thanks! How can I model it programming language independent? How to use multiplicity and collection attribute properties correctly, if I want to transform out of the class diagram later code, e.g. to Java or even to a XSD.

Moreover: How to define an attribute to be a map, e.g.
- itemMap: Map<ClassB, ClassC>

Key-Value-Coding can be modeled with an association class.

Syntactical representation of UML elements in a specific language is means of code generators. EA has a build-in generator with a proprietary scripting language (though i prefer to achieve even more using the API and simple file I/O).
