Class 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.
