IMetabaseUpdateNode.ParentNode

Syntax

Description

The ParentNode property returns a parent structure for the update object.

Comments

ParentNode returns Null for a root element of the update structure.

Example

Executing the example requires the update file C:\Update.pef. The repository should contain an object with the OBJ_FOR_PEF identifier. Add a link to the Metabase system assembly.

    Sub UserProc;
    Var
        MB: IMetabase;
        Update: IMetabaseUpdate;
        UFN: IMetabaseUpdateFolderNode;
        UpdateObj: IMetabaseUpdateObjectNode;
        ObjIndex: Integer;
        ParentNode: IMetabaseUpdateFolderNode;
    Begin
        MB := MetabaseClass.Active;
        Update := Mb.CreateUpdate;
        Update.LoadFromFileNF("C:\Update.pefx");
        UFN := Update.RootFolder;
        UpdateObj := UFN.Add(MetabaseUpdateNodeType.DataObject) As IMetabaseUpdateObjectNode;
        UpdateObj.Object := MB.ItemById("OBJ_FOR_PEF");
        ObjIndex := UpdateObj.Index;
        ParentNode := UpdateObj.ParentNode;
        ParentNode.MoveNode(ObjIndex, ParentNode, 0);
        Update.SaveToFileNF("C:\Update.pefx");
    End Sub UserProc;

After executing the example, OBJ_FOR_PEF will be added to the beginning of the list of update objects - C:\Update.pef. Changes are saved.
