This is the called behavior. Activity diagrams are used to model system behaviors, and the way in which these behaviors are related in an overall flow of the system (that is, dynamic element interactions). As mentioned above, states in state machine diagrams can be nested. Activities (and indirectly Activity diagrams) can be recursively decomposed ("nested") by alternating between Activity definitions and Call Behavior Action usages (See Usage Notes below.) Basically it mean that a state can contain substates and while being in a substate, the class will also fire transitions originating from the superstate. In UML, an activity diagram is used to display the sequence of activities. Draw the detailed work flow for the sub-activity.

Additional kinds of InvocationActions allow for the targeted sending of signals and other objects and the ability for broadcasting signals to available receivers. As mentioned above, states in state machine diagrams can be nested. You should not define output pins or outgoing data flows from the action. uml. This sub clause describes two concrete kinds of ActivityGroups, ActivityPartitions and InterruptibleActivityRegions.
