Class Operations in Diagrams

Operations from Classes can be represented by CallOperation Action elements on any diagram (such as an Activity, Custom or Analysis diagram). When an operation is shown as an Action, the notation of the element displays the name of the operation prefixed by the name of the Class from which it comes.

Notes

• If you want to locate, in the Browser window, the operation that an Action was created from, right-click on the Action in the diagram and select the 'Find | Locate Operation in Project Browser' option
• If you want to display the previously-generated code for the Class containing the operation, click on the Action in the diagram and press either Ctrl+E or F12; the 'Code Editor' view displays, with the code generated for the Class (if no code has been generated for the Class, the 'Code Editor' does not display)
• In a simulation, the CallOperation Action must have a calling operation and a target object ActionPin, the operation belonging to the object that comes from the target ActionPin; if you don't set these properties, simulation will be blocked at the Action
