State Group

The State group is used by State Machine diagrams to show the enableable states a Class or element might be in and the transitions from one state to another. These diagrams are often placed under a Class element in the Project Browser to illustrate how a particular element changes over time.

The State group provides elements common to State Machine diagrams; basically the State, start and end nodes and the Object Flow relation. State Machine diagrams are used to model the states or conditions that elements might be in at runtime, such as active, inactive, idle, accelerating or braking. States can have substates; for example, accelerate or brake might be substates of active.
