    • Deadline

      private Deadline(long deadlineMillis)
      Constructs a new instance with the given UNIX time in milliseconds.
      Parameters:

  • Method Details

    • calculate

      public static Deadline calculate(long timeMillis, TimeValue timeValue)

      timeMillis - A time in UNIX milliseconds, usually the current time.
      timeValue - time value to add to timeMillis.
      Returns:
      a deadline representing the current time plus the given time value.

    • calculate

      public static Deadline calculate(TimeValue timeValue)
      Calculates a deadline from now plus a given time value. Non-positive time values represent an indefinite timeout without a deadline.
      Parameters:
      timeValue - time value to add to timeMillis.
      Returns:
      a deadline representing the current time plus the given time value.
