类 RootReference<K,V>

java.lang.Object

org.h2.mvstore.RootReference<K,V>

public final class RootReference<K,V>
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.
