| PIStateLambda (std::function< void()> on_enter, std::function< void()> on_exit=nullptr, const PIString &n={}) | |
| Creates a state backed by enter and exit callbacks. | |
| void | onEnter () override |
| Executes the enter callback. | |
| void | onExit () override |
| Executes the exit callback. | |
 Public Member Functions inherited from PIStateBase | |
| PIStateBase (const PIString &n={}) | |

| virtual | ~PIStateBase () |
| Destroys the state together with owned child states and transitions. | |
| virtual void | onEnter () |
| Called when the state becomes active. | |
| virtual void | onExit () |
| Called when the state becomes inactive. | |
| virtual void | onFinish () |
| Called when a final child finishes this state. | |

| void | setInitialState (PIStateBase *s) |
| Sets the initial child state for a non-parallel compound state. | |
| PITransitionBase * | addTransition (PIStateBase *target, int event_id) |
| Adds an event-driven transition from this state to target. | |
| PITransitionTimeout * | addTimeoutTransition (PIStateBase *target, PISystemTime timeout) |
| Adds a timeout transition that fires while this state stays active. | |
| void | setParallel (bool yes) |
| Enables or disables parallel activation of child states. | |
| const PIString & | getName () const |
| Returns the state name. | |

| bool | isAtomic () const |
| Returns true if the state has no children. | |
| bool | isCompound () const |
