Class PmsgComplexStateMachine

java.lang.Object
java.util.Observable
pygar.state.PmsgComplexStateMachine
All Implemented Interfaces:
java.util.Observer
@ThreadSafe
public class PmsgComplexStateMachine
extends java.util.Observable
implements java.util.Observer
UNDER CONSTRUCTION!! NOT READY FOR USE This class implements a special type of compound state machine that is composed of instances of the PmessageStateMachine superclass. The specialization allows an instance of this class to receive messages and then route them to the component state machines based on the session, groupID, and senderID. The class itself exhibits three predefined states: sBegin, sActive, sEnd which correspond to the initial situation, the state when the entire state machine is active and the state reached when all the components have reached their final state. The class is modelled on StateMachine but it is not a subclass because we not want to support any but the predefined states; therefore, addTransition() is not available in this class. N.b. not currently in use anywhere. Requires modifications to use current version of other classes. See especially //TODO CRITICAL where code is commented out
