Java FSM Library : DynamicEasyFSM Files

EasyFSM (A Java Library; to facilitate Finite State Machine (FSM) creation.
---------------------------------------------------------------------------

Description:
------------

This library facilitates creation of a Finite State Machine (FSM).
Library generates a Finite State Machine (FSM) from a configuration
file specified while invoking the object for the FSM class.

Current library has been built as Java Library Project in Netbeans 7.0.1

Source code (EasyFSM.zip) can be extracted and built in a Netbeans IDE 
or can even be ported to an Eclipse environment.


Usage:
------

Just a test example for usage:

<Code>

    public static void testFSM() {
        try {
            FSM f = new FSM("C://config.xml", new FSMAction() {
                @Override
                public boolean action(String curState, String message, String nextState, Object args) {
                    javax.swing.JOptionPane.showMessageDialog(null, curState + ":" + message +" : " +nextState);
                    /*
                     * Here we can implement our login of how we wish to handle an action
                     */
                    return true;
                }
            });
            System.out.println(f.getCurrentState());
            f.ProcessFSM("MOVELEFT");
            System.out.println(f.getCurrentState());
            f.ProcessFSM("MOVE");
            System.out.println(f.getCurrentState());
            f.ProcessFSM("MOVERIGHT");
            System.out.println(f.getCurrentState());
        } catch (ParserConfigurationException ex) {
            Logger.getLogger(TestOwnCode.class.getName()).log(Level.SEVERE, null, ex);
        } catch (SAXException ex) {
            Logger.getLogger(TestOwnCode.class.getName()).log(Level.SEVERE, null, ex);
        } catch (IOException ex) {
            Logger.getLogger(TestOwnCode.class.getName()).log(Level.SEVERE, null, ex);
        }
    }

    public static void main(String[] args) {
        try {
            testFSM();
        } catch (Exception ex) {
            Logger.getLogger(TestOwnCode.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
    
</Code>

XML Configuration file should be of the following format:

<?xml version="1.0" encoding="UTF-8"?>
