      • getDeadline

        public static long getDeadline​(long timeout)
        Calculate the epoch timestamp when a timeout will expire. This deadline is computed by adding the timeout to System.currentTimeMillis(). This computation is protected against overflow, that is, the deadline will never exceed Long.MAX_VALUE. This allows the user to simply test if the deadline has passed by performing a check against the current epoch time: if (deadline <= System.currentTimeMillis()) { // deadline has passed }
        Parameters:
        timeout - the timeout to compute the deadline with. Must be >= 0 or an IllegalArgumentException will be thrown.
        Returns:
        the timestamp at which the timeout will expire, or Long.MAX_VALUE if the timeout causes an overflow.
