Classes
| Class | Description | |
|---|---|---|
 | AccessRightsValue | valid string values for the accessRights item property |
| BrowseNodeInfoWPF | WPF TreeViewItem additional OPC item information |
| BrowseTreeProperties | An instance of this class is contained in the XmlServer and BrowseTreeList objects. It's not intended to be instantiated otherwise. |
| DataBindFormat | Formatting and Transformation definitions. |
| DataBindInfo | DataBind item information passed to DataBind event handlers. If a bound property has this type then the set accessor gets an object of this type and acts as the callback handler. |
| DataBindList | DataBind subscription list as returned from the ListBuilder method GetDataBindList. |
| DataBindObjectLink | This definition links a DataLink Definition to an object in the user application. |
| DataBindSubscription | Data for one DataBind subscription |
| DefinitionList | The XML definition file is deserialized into such an object. |
| DefinitionListInfo | Info class returned by the QueryLists method. |

| ItemList | List definition class with a number of item definitions. The definitions on list level are the hierarchical parameters that may be defined on OPC XML-DA list level. |
| ListBuilder | This class contains methods to handle ItemLists and build request list for XML-DA server calls. The definition list XML files are typically created with the ListBuilder Tool. First the definition lists are loaded from an XML file that is on disk or embedded in the application EXE file. Then lists are extracted into objects required for the XML-DA server calls. Additional methods help writing dynamic data elements into the extracted list. |
