Interface MovingAverages

All Known Implementing Classes:

ExponentialMovingAverages, SlidingTimeWindowMovingAverages

public interface MovingAverages

A triple of moving averages (one-, five-, and fifteen-minute moving average) as needed by Meter.

Included implementations are:

• ExponentialMovingAverages exponential decaying average similar to the top Unix command.
• SlidingTimeWindowMovingAverages simple (unweighted) moving average

Method Summary

Modifier and Type	Method	Description
