Class FSMImpl

java.lang.Object
org.glassfish.pfl.basic.fsm.FSMImpl
All Implemented Interfaces:
FSM
public class FSMImpl extends 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.
