UML 2 Activity and Action Models

Object node in activity diagram Activity Activity In the browser an activity is placed in a class view , a use case view or a use case , and may contain parameters, expansion and interruptible activity regions , activity partitions , activity nodes activity action , object node or control node and activity diagrams . The activity's properties are exposed below. Activity parameter To simplify in Bouml a parameter is both a UML parameter and a UML parameter node, this means that the properties of a parameter also contains the properties of a parameter node. In the browser a parameter is placed under its activity and may contains flows. A flow can't directly connect two parameters, a parameter is connected through a flow to an expansion node or an activity node activity action , object node or control node whose must be in the activity owing the parameter. Note . parameter sets are defined on actions, see actions.
