Appendix C. UML at a Glance

Figure C.5. A statechart diagram shows transitions from state to state.

• Show a state in a rectangle with rounded corners.


• Show state transitions with open arrows.


• A statechart need not map directly to a class diagram or an object diagram, although
  you may arrange for a direct translation, as Figure 22.3 in Chapter 22, State, shows on
  page 230.
