_main_
Component root {
    
    /* Log Printer to receive a Message in Terminal */
    LogPrinter lp ("ivybus in: ")



    IvyAccess ivybus ("224.1.2.3:2010", "smala", "READY")
    {
        // define your regexs
        String my_regex ("smala (\\S*)")
        //...
    }

    /* creating a connector to display incomming messages in the text */
    ivybus.in.my_regex.[1] => lp.input



   
    Clock cl (1000)
    /* write on the bus any String or textProperty */

    /* every second we write on the bus: smala Hello */
