I want to display the multiplicity of a class at the right corner of the class icon. for example, to display 1 at the right hand corner of the class to mark as a singleton class. How can I do that using staruml?

Hi,

Is the notation specified in UML standard specification?

Thanks,

Hello,

Yes, this is a standard specification if I am not wrong.

From OMG, UML Specification 2.5.1, 11.2.3.4 Multiplicities and topologies:

> The multiplicities on ConnectableElements constrain the number of objects that may be created within an instance of the containing StructuredClassifier, according to the semantics of MultiplicityElement.

From the same specification, 11.2.4 Notation:

> The multiplicity for a Property may also be shown as a multiplicity mark in the top right corner of the part box.

Additionally, from "The Unified Modeling Language User Guide" by Grady Booch, et al., Figure 9-6 Multiplicity.

I suppose currently there is no support for this with StarUML Version 4.1.6.

Let me know if there is any way.

Sincerely,

Kenan

Hello,

The 2nd Edition of the UML User Guide had multiplicities for classes as shown by its Figure 9-6.

However, section 7.5 of the OMG Spec 2.5.1 indicates that multiplicities apply to Multiplicity Elements and section 7.8.8.4 indicates that only Variables, Connector Ends, Parameters, Structural Features and Pins are Multiplicity Elements. Therefore, multiplicities apply to attributes, association ends, parts, Ports, etc. but not to Classifiers like Classes anymore.

OMG section 11.2.3.4 is about the multiplicities Connectable Elements (and their Connectors) which are Structural Features (Properties/attributes) of Structured Classifiers (Collaborations and Classes).

Regards, Jean
