    copied!<p>TL;DR: How should I represent a UML Transition (see next line) in a UML Object Diagram?</p> <blockquote> <p>event(event_parameters) [guard_condition] / doStuff()</p> </blockquote> <p>In my BSc thesis project, I am working with UML StateMachines (behavioural, no protocol SMs). Besides the State Machine Diagram representation, I require Object Diagrams.</p> <p>So far, however, I have not managed to accurately represent transitions. I'd like to be able to show transitions that have a trigger (event), a guard (constraint) and/or behaviour.</p> <p>I have searched for related questions (<a href="https://stackoverflow.com/questions/51464/how-do-you-show-events-in-uml-class-diagrams">this one</a> comes close, but doesn't provide the exact information I'm looking for), as well as read the relevant parts of the UML Superstructure, but still can't quite figure it out.</p> <p>So far, I've created an Object Diagram based on the state S1 (and all transitions) shown in the State Machine Diagram below. I should note that I have only added events, since guard and behaviour are giving me similar problems (and would clutter the diagram).</p> <p>State Machine Diagram containing state S1</p> <p><img src="https://i.stack.imgur.com/qvL6d.png" alt="State Machine Diagram containing state S1"></p> <p>(incorrect) Object Diagram for S1, including all transitions (I'm assuming that at least the SignalEvent instances are (somewhat) incorrect.)</p> <p><img src="https://i.stack.imgur.com/fsks7.png" alt="(incorrect) Object Diagram for S1, including all transitions (I&#39;m assuming that at least the SignalEvent instances are (somewhat) incorrect.)"></p>
