|---|---|
| Generic | LookupItemIDs requests are handled in the generic server. NSPlugin.dll is not involved. The generic server creates a thread that calls every 2 seconds the method GetPropertyValue() to update the value of the property item in the generic server cache. |
| GenericNoUpdate | Behaves as mode "Intern" but doesn't start the property value update thread. Servers with only constant property values can prevent the update thread overhead. |
| PluginHandled | Property items are handled much like regular items. On LookupItemIDs client requests the generic server call the plug-in method LookupItemID(). This method creates the property item by calling the generic server method AddItem(). The plug-in must update the value of this item by calling the SetItemValue() method. |
