OrientDB Register Hooks

I just tried all the hooks on orientdb, but I'm not sure how to register the ORecordHooks on my graph.

OrientGraph graph = new OrientGraph("remote:localhost/test");
MyHook hook = new MyHook();

      

        
        
        
      

    

The MyHook class looks like this:

public class MyHook extends ORecordHookAbstract implements
        ODatabaseLifecycleListener {

    public MyHook() {
        Orient.instance().addDbLifecycleListener(this);
    }
    @Override
    public DISTRIBUTED_EXECUTION_MODE getDistributedExecutionMode() {
        System.out.println("0");
        return null;
    }
    @Override
    public PRIORITY getPriority() {
        System.out.println("1");
        return PRIORITY.FIRST;
    }
    @Override
    public void onRecordAfterCreate(ORecord iRecord) {
        System.out.println("2");
    }
    @Override
    public RESULT onRecordBeforeCreate(ORecord iRecord) {
        System.out.println("3");
        return ORecordHook.RESULT.RECORD_CHANGED;
    }
    @Override
    public RESULT onRecordBeforeRead(ORecord iRecord) {
        System.out.println("4");
        return ORecordHook.RESULT.RECORD_CHANGED;
    }
    @Override
    public void onRecordAfterRead(ORecord iRecord) {
        System.out.println("5");
    }
    @Override
    public RESULT onRecordBeforeUpdate(ORecord iRecord) {
        System.out.println("6");
        return ORecordHook.RESULT.RECORD_CHANGED;
    }
    @Override
    public void onRecordAfterUpdate(ORecord iRecord) {
        System.out.println("7");
    }
    @Override
    public RESULT onRecordBeforeDelete(ORecord iRecord) {
        System.out.println("8");
        return ORecordHook.RESULT.RECORD_CHANGED;
    }
    @Override
    public void onRecordAfterDelete(ORecord iRecord) {
        System.out.println("9");
    }
    @Override
    public void onCreate(ODatabaseInternal iDatabase) {e
        System.out.println("10");
        iDatabase.registerHook(this);
    }
    @Override
    public void onOpen(ODatabaseInternal iDatabase) {
        System.out.println("11");
        iDatabase.registerHook(this);
    }
    @Override
    public void onClose(ODatabaseInternal iDatabase) {
        System.out.println("12");
        iDatabase.unregisterHook(this);
    }
    @Override
    public void onCreateClass(ODatabaseInternal iDatabase, OClass iClass) {
        System.out.println("13");
    }
    @Override
    public void onDropClass(ODatabaseInternal iDatabase, OClass iClass) {
        System.out.println("14");
    }
}

      

        
        
        
      

    

After creating and removing the bundle of vertices and edges, only Hooks 1, 13 and 12 fire, so this will be getPriority (), onCreateClass () and onClose (). Why aren't any of my ORecordHooks shooting?
