Functions

build

fun build(): StateMachineDefinition<S, E, C, A, R>

Returns the completed fsm.

default

fun default(handler: DslStateMapDefaultEventHandler<S, E, C, A, R>.() -> Unit): DslStateMapDefaultEventHandler<S, E, C, A, R>

Defines a section for default behaviour for the state machine.

initialState

fun initialState(deriveInitialState: StateQuery<C, S>): DslStateMachineHandler<S, E, C, A, R>

Defines an expression that will determine the initial state of the state machine based on the values of the context.

initialStates

fun initialStates(deriveInitialMap: StateMapQuery<C, S>): DslStateMachineHandler<S, E, C, A, R>

Provides for a list of pairs with state and map name that will be pushed and the last entry will be popped and become the current map. This is required when using state machine with named maps.

invariant

fun invariant(message: String, condition: Condition<C>): DslStateMachineHandler<S, E, C, A, R>

onStateChange

fun onStateChange(action: StateChangeAction<C, S>)

Defines an action that will be invoked after a transition to a new state. Any exceptions thrown by the action will be ignored.

stateMap

fun stateMap(name: String, validStates: Set<S>, handler: DslStateMapHandler<S, E, C, A, R>.() -> Unit): DslStateMapHandler<S, E, C, A, R>

creates a named statemap

whenState

fun whenState(currentState: S, handler: DslStateMapEventHandler<S, E, C, A, R>.() -> Unit): DslStateMapEventHandler<S, E, C, A, R>

Defines a section for a specific state.
