public abstract class FiniteStateMachine<STATE extends Enum<?>,EVENT extends Enum<?>,SUBJECT> extends Lifecycle

A finite state machine that is based on a matrix of transitions.

A finite state machine can fire the following events:

FiniteStateMachine<STATE extends Enum<?>,EVENT extends Enum<?>,SUBJECT>.StateChangedEvent after state changes of a subject.
