StepLong (Spectator)

java.lang.Object
- com.netflix.spectator.impl.StepLong

All Implemented Interfaces:

StepValue
```
public class StepLong
extends Object
implements StepValue
```
Utility class for managing a set of AtomicLong instances mapped to a particular step interval. The current implementation keeps an array of with two items where one is the current value being updated and the other is the value from the previous interval and is only available for polling.
This class is an internal implementation detail only intended for use within spectator. It is subject to change without notice.
