Class SegmentNodeStore

java.lang.Object

org.apache.jackrabbit.oak.segment.SegmentNodeStore

All Implemented Interfaces:

org.apache.jackrabbit.oak.spi.commit.Observable, org.apache.jackrabbit.oak.spi.state.NodeStore

public class SegmentNodeStore
extends Object
implements org.apache.jackrabbit.oak.spi.state.NodeStore, org.apache.jackrabbit.oak.spi.commit.Observable

The top level class for the segment store.

The root node of the JCR content tree is actually stored in the node "/root", and checkpoints are stored under "/checkpoints".
