The UAF Service Functions State viewpoint enables you to get a state-like view of Service Data Flows (which are really the state of a ServiceFunction as it is doing something – sending resources to another ServiceFunction) and ServiceFunctions (which are analogous to the transition of a ServiceFunction from one state to another).
One easy way to model this viewpoint is to:
1 Open the Choices dialog (right-click diagram workspace, and then select Choices) – and select-and-drag Service Data Flows already created in the encyclopedia onto the diagram workspace.
2 Optionally select Format > Symbol Format > Line Style and choose the line style – usually Elliptical Arcs or Straight – Any Orientation work well for a state-machine diagram.
3 Build transitions between the Service Data Flows (represented as circular state nodes) – the transitions are actually the Service Functions needed in the architecture.
