public final class GerritTriggerTimer {

    
Average number of milliseconds in a second.
    private static final long MILLISECONDS_PER_SECOND = 1000;
    
Wait this many milliseconds before the first call to a TimerTask
    private static final long DELAY_MILLISECONDS  =  5000;
    private static final Logger logger = LoggerFactory.getLogger(GerritTriggerTimer.class);

    
The instance used by the singleton mechanism.
    private static GerritTriggerTimer instance = null;

    
The timer that is doing the actual scheduling.
    private Timer timer = null;

    
The private constructor (this is a singleton class).
    private GerritTriggerTimer() {
         = new Timer(true);
    }

    
Returns the instance, and creates it first if needed.

Returns:
the instance of this class
    public static GerritTriggerTimer getInstance() {
        if ( == null) {
             = new GerritTriggerTimer();
        }
        return ;
    }

    public void schedule(TimerTask timerTask) {
        long timerPeriod = 
                * PluginImpl.getInstance().getConfig().getDynamicConfigRefreshInterval();
        try {
            .schedule(timerTasktimerPeriod);
        } catch (IllegalArgumentException iae) {
            .error("Attempted use of negative delay"iae);
        } catch (IllegalStateException ise) {
            .error("Attempted re-use of TimerTask"ise);
        }
