Issue 8414: Section: 14 (uml2-rtf) Source: (, ) Nature: Clarification Severity: Minor Summary: How to show class operation calls in interaction diagrams? A discussion in the umlforum list came to the conclusion that the name in the lifeline header should be the class name. In that case it is not possible to differentiate between "ClassName" only and "RoleName" only. Besides the notational problem I can't see how a class operation call could fit into the interaction meta-model. However it is necessary to show such a call. It's a typical part of an interaction. Resolution: Merged with 18697 Revised Text: Actions taken: March 1, 2005: received issue February 20, 2015: closed issue Discussion: The issue here is to be able to describe calls on static methods. Sequence diagrams in UML 2 do not cover this. It is possible to suggest that the lifeline header text be augmented by the possibility to write class as a keyword before the class name. This would indicate that the lifeline represents the imaginary object performing static methods of that class. There will, however, be cascading effects on static requirements since this lifeline does not have any counterpart in the composite structure of the enclosing classifier. For reasons of time pressure, we suggest to defer.
