Interface Summary

Interface	Description
EventTypeClassifier<E,T>	A functional interface to determine the event type of an event.
EventWithType<T>	An interface to be implemented by Events that are distinct from their types.
GenericStateMachine
Guard<E,C>	A functional interface to determine whether a transition is eligible or not.
SimpleStatefulStateMachine<S,E,T>
SimpleStateMachine<S,E,T>	A state machine.
StatefulStateMachine<S,E,T>
StatefulStateMachineWithContext<S,E,T,C>
StateMachine<S,E,T>
StateMachineListener<S,E,T,C>	A marker interface for all kinds of listeners that can be attached to a state machine by StateMachineBuilder.withListener(StateMachineListener).
StateMachineWithContext<S,E,T,C>	A SimpleStateMachine with a computational context.
StateWithEnterHandler<E,C>	An interface to be implemented by States that handle incoming events.
StateWithExitHandler<E,C>	An interface to be implemented by States that handle outgoing events.
StateWithParent<S>
TransitionListener<S,E,T,C>	A transition listener is invoked after a state is exited and before a new state is entered.
