Class FSMImpl

  • All Implemented Interfaces:
    FSM

    public class FSMImpl
    extends java.lang.Object
    implements FSM
    This is the main class that represents an instance of a state machine using a state engine. It may be used as a base class, in which case the guards and actions have access to the derived class. Note that this is optional; an FSM implementation may directly implement the FSM interface if desired.
