IRdsSortAttributes.LoadFrom

Fore Syntax

LoadFrom(Element: Variant);

Fore.NET Syntax

LoadFrom(Element: object);

Parameters

Element. Object, from which parameters of attribute values sorting will be loaded.

Description

The LoadFrom method loads parameters of attribute values sorting from XML.

Comments

Use IRdsSortAttributes.SaveTo to save parameters of attributes' sorting.

Fore Example

Executing the example requires that the repository contains an MDM repository with the RDS identifier. This repository must contain a table MDM dictionary with the D_EXP_IMP identifier, that includes export schemes. The file system must contain the file C:\SortAtt.xml, that stores options of filter applied to attribute values in export scheme of the dictionary in XML format.

Add links to the Metabase, Rds and Xml system assemblies.

Sub UserProc;
Var
    mb: IMetabase;
    rdsKey: Integer;
    dictObj: IMetabaseObject;
    Dict: IRdsDictionary;
    sExport: IMetaRdsExportSchema;
    dictSort: IRdsSortAttributes;
    Doc: IXmlDomDocument;
Begin
    mb := MetabaseClass.Active;
    // Get key of the MDM repository
    rdsKey := mb.GetObjectKeyById("RDS");
    // Get table MDM dictionary
    dictObj := mb.ItemByIdNamespace("D_EXP_IMP", rdsKey).Edit;
    Dict := dictObj As IRdsDictionary;
    // Get the first export scheme
    sExport := Dict.ExportSchemas.Item(0) As IMetaRdsExportSchema;
    // Get sorting parameters
    dictSort := sExport.SortAttributes;
    // Load sorting parameters from file
    Doc := New DOMDocument.Create;
    Doc.load("C:\SortAtt.xml");
    dictSort.LoadFrom(Doc.documentElement);
    // Save the dictionary
    dictObj.Save;
End Sub UserProc;

After executing the example attribute sorting parameters in the first export scheme are loaded from the file C:\SortAtt.xml.

    // Save the dictionary
    dictObj.Save();
End Sub;

After executing the example attribute sorting parameters in the first export scheme are loaded from the file C:\SortAtt.xml.
