  • Method Details

    • mark

      void mark()
      Mark the occurrence of an event.

    • mark

      void mark(long n)
      Mark the occurrence of a given number of events.
      Parameters:
      n - the number of events

    • getCount

      long getCount()
      Description copied from interface: Metered
      Returns the number of events which have been marked.
      Specified by:
      getCount in interface Counting
      Specified by:
      getCount in interface Metered
      Returns:
      the number of events which have been marked

    • getFifteenMinuteRate

      double getFifteenMinuteRate()
      Description copied from interface: Metered
      Returns the fifteen-minute exponentially-weighted moving average rate at which events have occurred since the meter was created. This rate has the same exponential decay factor as the fifteen-minute load average in the top Unix command.
      Specified by:
      getFifteenMinuteRate in interface Metered
      Returns:
      the fifteen-minute exponentially-weighted moving average rate at which events have occurred since the meter was created

    • getFiveMinuteRate

      double getFiveMinuteRate()
      Description copied from interface: Metered
      Returns the five-minute exponentially-weighted moving average rate at which events have occurred since the meter was created. This rate has the same exponential decay factor as the five-minute load average in the top Unix command.
      Specified by:
      getFiveMinuteRate in interface Metered
      Returns:
      the five-minute exponentially-weighted moving average rate at which events have occurred since the meter was created

    • getMeanRate

      double getMeanRate()
      Description copied from interface: Metered
      Returns the mean rate at which events have occurred since the meter was created.
      Specified by:
      getMeanRate in interface Metered
      Returns:
      the mean rate at which events have occurred since the meter was created

    • getOneMinuteRate

      double getOneMinuteRate()
      Description copied from interface: Metered
      Returns the one-minute exponentially-weighted moving average rate at which events have occurred since the meter was created. This rate has the same exponential decay factor as the one-minute load average in the top Unix command.
      Specified by:
      getOneMinuteRate in interface Metered
      Returns:
      the one-minute exponentially-weighted moving average rate at which events have occurred since the meter was created
