RootReference (Nitrite MVStore Adapter 4.2.1 API)

java.lang.Object
- org.dizitart.no2.mvstore.compat.v1.mvstore.RootReference

```
public final class RootReference
extends Object
```
Class RootReference is an immutable structure to represent state of the MVMap as a whole (not related to a particular B-Tree node). Single structure would allow for non-blocking atomic state change. The most important part of it is a reference to the root node.
