Creating MDM Dictionary Elements

The user can work with hierarchy of MDM dictionary elements using methods of the IRdsDictionaryElements interface.

Executing the example requires an MDM dictionary with the RDS_DICT identifier.

Example

Add links to the Metabase, Rds system assemblies.

Sub UserProc;
Var
    MB: IMetabase;
    Dict: IRdsDictionary;
    Attrs: IRdsAttributes;
    DictInst: IRdsDictionaryInstance;
    Elements: IRdsDictionaryElements;
    Data: IRdsDictionaryElementData;
    i, j: Integer;
Begin
    MB := MetabaseClass.Active;
    Dict := MB.ItemById("RDS_DICT").Bind As IRdsDictionary;
    Attrs := Dict.Attributes;
    DictInst := Dict.Open(Null);
    Elements := DictInst.Elements;
    Data := Elements.CreateData;
    Data.Value(Data.AttributeIndex(Attrs.Name.Key)) := "First root";
    i := Elements.Insert(-2, Data);
    Data.Value(Data.AttributeIndex(Attrs.Name.Key)) := "Second root";
    j := Elements.Insert(-2, Data);
    Data.Value(Data.AttributeIndex(Attrs.Name.Key)) := "First child";
    Elements.Insert(i, Data);
    Data.Value(Data.AttributeIndex(Attrs.Name.Key)) := "Second child";
    Elements.Insert(j, Data);
End Sub UserProc;

After executing the example four new elements are created in the MDM dictionary: two root elements and one child element for each root one.
