Methods
private
getPreInitialState(actorCtx: AnyActorContext, initEvent: any): State<TContext, TEvent, TResolvedTypesMeta>The initial state before evaluating any microsteps. This "pre-initial" state is provided to initial actions executed in the initial state.
createState(stateConfig: State<TContext, TEvent, TResolvedTypesMeta> | StateConfig<TContext, TEvent>): State<TContext, TEvent, TResolvedTypesMeta>
getInitialState(actorCtx: ActorContext<TEvent, State<TContext, TEvent, TResolvedTypesMeta>>, input?: any): State<TContext, TEvent, TResolvedTypesMeta>
Returns the initial State instance, with reference to self as an ActorRef.
getStateNodeById(stateId: string): StateNode<TContext, TEvent>
getStatus(state: State<TContext, TEvent, TResolvedTypesMeta>)
getTransitionData(state: State<TContext, TEvent, TResolvedTypesMeta>, event: TEvent): Array<TransitionDefinition<TContext, TEvent>>
microstep(): Array<State<TContext, TEvent, TResolvedTypesMeta>>
Determines the next state given the current state and event.
Calculates a microstep.
provide(implementations: InternalMachineImplementations<TContext, TEvent, TResolvedTypesMeta, true>): StateMachine<TContext, TEvent, TAction, TActorMap, AreAllImplementationsAssumedToBeProvided<TResolvedTypesMeta> extends false ? MarkAllImplementationsAsProvided<TResolvedTypesMeta> : TResolvedTypesMeta>
Clones this state machine with the provided implementations
and merges the context (if provided).
resolveState(state: State<TContext, TEvent, TResolvedTypesMeta>): state
Resolves the given state to a new State instance relative to this machine.
This ensures that .nextEvents represent the correct values.
resolveStateValue(stateValue: StateValue, ...unnamed 1: Equals<TContext, MachineContext> extends true ? [] : [TContext]): State<TContext, TEvent, TResolvedTypesMeta>
restoreState(state: PersistedMachineState<State<TContext, TEvent, TResolvedTypesMeta>>, _actorCtx: ActorContext<TEvent, State<TContext, TEvent, TResolvedTypesMeta>>): State<TContext, TEvent, TResolvedTypesMeta>

transition(): State<TContext, TEvent, TResolvedTypesMeta>
state: State<TContext, TEvent, TResolvedTypesMeta>,
event: TEvent,
actorCtx: ActorContext<TEvent, State<TContext, TEvent, any>>,
Determines the next state given the current state and received event.
Calculates a full macrostep from all microsteps.
