Method Detail

when

public TransitionBuilder<S,E> when(S state)

Start defining a Transition from state state.

Parameters:

state - the state the transition begins in.

Returns:

a TransitionBuilder.

onInternalTransition

public ViaBuilder<S,E> onInternalTransition(S state)

Start defining an Action that will be executed after an internal transition from/to state.

The criteria for the event that causes this transition is defined on the returned ViaBuilder.

Parameters:

state - the state experiencing an internal transition.

Returns:

a ViaBuilder.

onTransitionTo

public ActionToBuilder<S,E> onTransitionTo(S state)

Start defining an Action that will executed after a transition to state.

Further criteria for execution will be defined on the returned ActionToBuilder.

Parameters:

state - the state being transitioned to.

Returns:

an ActionToBuilder.

onTransitionTo

public ActionToBuilder<S,E> onTransitionTo(java.util.function.Predicate<S> filter)

Start defining an Action that will execute after a transition to any state that passes filter.

Further criteria for execution will be defined on the returned ActionToBuilder.

Parameters:

filter - the filter for states being transitioned to.

Returns:

an ActionToBuilder.

onTransitionFrom

public ActionFromBuilder<S,E> onTransitionFrom(S state)

Start defining an Action that will execute after a transition from state.

Parameters:

state - the state being transitioned from.

Returns:

an ActionFromBuilder.

onTransitionFrom

public ActionFromBuilder<S,E> onTransitionFrom(java.util.function.Predicate<S> filter)

Start defining an Action that will execute after a transition from any state that passes filter.

Parameters:

filter - the filter for states being transitioned from.

Returns:

an ActionFromBuilder.

addTransition

public void addTransition(Transition<S,E> transition)

Add a manually defined Transition.

Parameters:

transition - the Transition to add.

addTransitionAction

public void addTransitionAction(TransitionAction<S,E> transitionAction)

Add a manually defined TransitionAction.

Parameters:

transitionAction - the TransitionAction to add.

build

public Fsm<S,E> build(S initialState)
