Example

Executing the example requires an ETL task with the ETL identifier.

Add links to the Etl and Metabase system assemblies.

Sub UserProc;
Var
    MB: IMetabase;
    EtlTask: IEtlTask;
    Links: IEtlPlainLinks;
    Link: IEtlPlainLink;
    Output: IEtlPlainOutput;
    FileMapp: IEtlPlainLinkFieldMapping;
    Type: Integer;
    Field: IEtlPlainField;
Begin
    MB := MetabaseClass.Active;
    EtlTask := MB.ItemById("ETL").Bind As IEtlTask;
    // Get link between data source and data consumer
    Links := EtlTask.Links;
    Link := Links.Item(0);
    // Get output field
    Output := Link.SourceObjectOutput;
    Field := Output.Fields.Item(0);
    FileMapp := Link.Link(Field);
    // Get link type of data source field
    Type := FileMapp.Type;
    Debug.WriteLine("Link type: " + Type.ToString);
End Sub UserProc;

After executing the example the console window displays a message about link type of data source field of ETL task.
