public static <R> R retry(long time, TimeUnit unit, long sleepMillis, Callable<R> operation, Predicate<Exception> retryPredicate, R defaultResult) throws InterruptedException Retries for given amount of time (time, unit) the passed in operation, sleeping givensleepMills
between retries. In case operation returnsnull
, it is assumed "is not done yet" state, so retry will happen (if time barrier allows). If time barrier passes, and stillnull
("is not done yet") is returned from operation, thedefaultResult
is returned.- Throws:
