    • Method Detail

      • wallClockTime

        long wallClockTime()
        Returns:
        the current clock time in milliseconds. Note that it depends of the system time.

      • time

        long time()
        Returns:
        the current cpu time in nanoseconds. Note that some platforms do not provide nanosecond precision.

      • instant

        Instant instant()
        Returns:
        the current Instant. Similarly to time(), note that some platforms do not provide nanosecond precision.

      • timeDuration

        long timeDuration​(long startTimeNanos,
                  TimeUnit outputTimeUnit)
        It is equivalent to timeDuration(startTime, time(), outputTimeUnit).
        Parameters:
        startTimeNanos - start cpu time in nanoseconds, usually returned by time().
        outputTimeUnit - the TimeUnit of the returned value.
        Returns:
        the duration between the current cpu time and startTime. It returns zero if startTime is less than zero or if startTime is greater than the current cpu time.

      • timeDuration

        long timeDuration​(long startTimeNanos,
                  long endTimeNanos,
                  TimeUnit outputTimeUnit)
        Parameters:
        startTimeNanos - start cpu time in nanoseconds, usually returned by time().
        endTimeNanos - end cpu time in nanoseconds, usually returned by time().
        outputTimeUnit - the TimeUnit of the returned value.
        Returns:
        the duration between the endTime and startTime. It returns zero if startTime or endTime are less than zero or if startTime is greater than the endTime.

      • isTimeExpired

        boolean isTimeExpired​(long endTimeNanos)
        Parameters:
        endTimeNanos - a cpu time in nanoseconds, usually returned by time()
        Returns:
        true if the endTime is less or equals than the current cpu time.

      • remainingTime

        long remainingTime​(long endTimeNanos,
                   TimeUnit outputTimeUnit)
        Parameters:
        endTimeNanos - the end cpu time in nanoseconds.
        outputTimeUnit - the TimeUnit of the returned value.
        Returns:
        the remaining cpu time until the endTime is reached.

      • expectedEndTime

        long expectedEndTime​(long duration,
                     TimeUnit inputTimeUnit)
        Parameters:
        duration - the duration.
        inputTimeUnit - the TimeUnit of the duration.
        Returns:
        the expected end time in nano seconds. If duration is less or equals to zero, the current cpu time is returned (time()).
