public class ActivityState

extends SubmachineState

An activity state represents the execution of a non-atomic sequence of steps that has some duration (i.e., internally it consists of a set of actions and possibly waiting for events). That is, an activity state is a “hierarchical action”, where an associated sub-activity model is executed.

An ActivityState is a SubmachineState that executes a nested activity model. When an input transition to the ActivityState is triggered, execution begins with the initial state of the nested ActivityModel. The outgoing Transition of an ActivityState is enabled when the final state of the nested ActivityModel is reached (i.e., when it completes its execution).

The semantics of an ActivityState are equivalent to the model obtained by statically substituting the contents of the nested model as a composite state replacing the activity state.
