The mode can be one of the following constant values: | Constant | Meaning | |---|---| | DD_Lock_On_All | Lock on all saves and deletes (default) | | DD_Lock_On_New_Save_Delete | Lock on new saves and deletes | | DD_Lock_On_Save | Lock on all saves | | DD_Lock_On_New_Save | Lock only on new saves | | DD_Lock_On_Delete | Lock only on deletes |
