14 * Description: CNssVasDbBuilder is owned by CNssVASDBMgr. It is responsible for creating |

15 * the context manaher, tag manager, vas db event notifier, and tag select |
|
16 * notifier. This class is a singleton, and is created using the InstanceL(), |
|
17 * and deleted using the RemoveInstance() methods. |
