stopInTheNextMinute

public static void stopInTheNextMinute()

Tell The system that should stop

Returns:

generateEvents

public void generateEvents()

Generates new time table entries (for new events). IN fact this method does more or less everything, this method tells the DAO to look for CrontabEntryArray, generates the CrontabBeans and puts itself as the last event to generate again the list of events. Nice Method. :-)
