Class Automaton

java.lang.Object

alice.util.Automaton

All Implemented Interfaces:

Serializable, Runnable

Direct Known Subclasses:

CUIConsole

public abstract class Automaton
extends Object
implements Runnable, Serializable

this abstract class is the base class for implementing automaton abstraction automaton state behaviour is expressed in public method and the become method allows to move computation from state to state method representing state must be public (to allow correct behaviour of reflection)
