ExponentialMovingAverages (Metrics Core 4.1.9 API)

java.lang.Object
- com.codahale.metrics.ExponentialMovingAverages

All Implemented Interfaces:

MovingAverages
```
public class ExponentialMovingAverages
extends Object
implements MovingAverages
```
A triple (one, five and fifteen minutes) of exponentially-weighted moving average rates as needed by Meter.
The rates have the same exponential decay factor as the fifteen-minute load average in the top Unix command.
