public void doDelay(final int retryCounter) throws InterruptedException {
    if (retryDelay > 0 || randomBackOff) {
        long sleepFor;
        sleepFor = exponentialBackOff ? (retryDelay << retryCounter) : (randomBackOff ? new Random().nextInt((int) (maximumRetryDelay > 0 ? maximumRetryDelay : DEFAULT_MAXIMUM_RETRY_DELAY)) : retryDelay);
        if (maximumRetryDelay > 0 && sleepFor > maximumRetryDelay) {
            sleepFor = maximumRetryDelay;
        }
        Thread.sleep(sleepFor);
    }
}
