open class DefaultStatesMachine < T : State >(statesManager: StatesManager < T >, handlers: List < CheckableHandlerHolder <in T , T >>, onStateHandlingErrorHandler: StateHandlingErrorHandler < T > = defaultStateHandlingErrorHandler()) : StatesMachine < T > (source)

Default realization of StatesMachine. It uses statesManager for incapsulation of States storing and contexts resolving, and uses launchStateHandling for State handling.
