code: @Override
      public void addValuesForField() {
          String objID = m_dbObj.getObjectID();
          assert !Utils.isEmpty(objID);
          m_dbTran.addIDValueColumn(m_tableDef, objID);
          m_dbTran.addAllObjectsColumn(m_tableDef, objID, m_tableDef.getShardNumber(m_dbObj));
      }
docs: and the encoded object ID as the value.
