org.apache.jackrabbit.oak.plugins.version.VersionHook

All Implemented Interfaces:

CommitHook

public class VersionHook
extends java.lang.Object
implements CommitHook

This class gathers together editors related to handling version storage:

1. VersionEditorProvider
   • VersionEditor - creates version history, handles checking-in, checking-out and restoring, prevents a checked-in node from being modified,
   • VersionStorageEditor - validates changes on the version storage,
2. VersionableCollector - collects all existing versionable UUIDs, so assigned histories won't be removed in the next step,
3. OrphanedVersionCleaner - removes all histories that are empty and have no longer a parent versionable node.
