Activity Diagram - Frame Notation and Parameters
This section describes the Activity Frame Notation used in a UML Activity Diagram. An Activity Frame Notation provides a boundary to enclose all actions and objects of the activity.
An Activity Frame Notation is a graphical notation used in a UML Activity Diagram to provide a boundary to enclose all actions and objects of the activity.
An Activity Frame Notation is drawn as a large rectangle with rounded corners. The activity name, input parameters and output parameters are written near the top left corner of the rectangle.
Object Notations representing input parameters and output parameters can be placed on edges of the rectangle.
For example, the "Bubble Sorting" activity requires an input parameter, an unsorted list, and an output parameter,
a sorted list. This activity can be drawn with an Activity Frame Notation in a UML activity diagram as shown below:
