![]() To restrict flow on a Sequence Flow set the conditionType Tagged Value to 'Expression' and create the script in the conditionExpression Tagged Value.Ī Decision node is used to explicitly model a decision being made. These differ from UML Activity diagrams in that all valid sequence flows are taken by default. To restrict flow on a Control Flow, add a Guard.Ī Sequence Flow is used to connect the elements on a Business Process diagram. ![]() ![]() A distinguishing feature is that only a single Control Flow can be followed from any node, except for an explicit Fork Node. These typically describe different methods of execution (for example Manual) as opposed to what happens.Ī Control Flow is used to connect the elements on an Activity diagram. A number of different Task Types are available. The basic behavior unit in an Activity is the Activity element. UML provides many different forms of Actions, although the simulation makes use of a small subset of these. The basic behavior unit in an Activity is the Action element. This implies a specific cause for the Activity to start, although it could be unspecified. The starting point is defined by a Start Event. No method of specifying why the Activity was started is available. The starting point is defined by an Initial Node.
