IEaxDataAreaTransformations.IndexOf

Fore Syntax

IndexOf(Value: IEaxDataAreaTransformation): Integer;

Fore.NET Syntax

IndexOf(Value: Prognoz.Platform.Interop.Express.IEaxDataAreaTransformation): integer;

Parameters

Value. Data transformation formula.

Description

The IndexOf method returns index of the specified data transformation formula.

Comments

To move data transformation formula inside collection, use IEaxDataAreaTransformations.MoveTo.

Fore Example

Executing the example requires that the repository contains an express report with the EXPRESS identifier containing table. The table contains two formatted formulas.

Add links to the Dimensions, Express, Metabase system assemblies.

Sub UserProc;
Var
    MB: IMetabase;
    Express: IEaxAnalyzer;
    Slice: IEaxDataAreaSlice;
    TrsCalc: IEaxDataAreaTransformations;
    TrCalc_a, TrCalc_b: IEaxDataAreaTransformation;
    SelSet: IDimSelectionSet;
    TransArray: IEaxTransformationTargetsArray;
    i: Integer;
    Tr: IEaxDataAreaTransformation;
Begin
    // Get repository
    MB := MetabaseClass.Active;
    // Get express report
    Express := MB.ItemById("EXPRESS").Edit As IEaxAnalyzer;
    // Get data slice
    Slice := Express.DataArea.Slices.Item(0);
    // Get collection of data transformation formulas
    TrsCalc := Slice.CalcTransformations;
    // Get data transformation formulas
    TrCalc_a := TrsCalc.Item(0);
    TrCalc_b := TrsCalc.Item(1);
    // Move indexes of data transformation formulas
    TrsCalc.MoveTo(1, 0);
    // Display to the console
    Debug.WriteLine
    ("Index of moved data transformation formula = " + TrsCalc.IndexOf(TrCalc_b).ToString);
    // Get selection and display elements of dimension for which formula is set
    SelSet := TrsCalc.TransformationsSelection;
    Debug.WriteLine("Elements in selection - " + SelSet.Item(0).ToString("", ", ", False));
    // Display to the console expression transforming data
    TransArray := TrsCalc.TransformationElements(Null);
    For i := 0 To TransArray.Count - 1 Do
        Tr := TransArray.Transformation(i);
        Debug.WriteLine("Data transformation formula - " + Tr.Expression.AsString);
    End For;
    // Save changes
    (Express As IMetabaseObject).Save;
End Sub UserProc;

After executing the example:

Data transformation formulas exchange indexes.
The console displays index of moved formula.
The console displays elements for which data transformation formula is set.
The console displays expressions of data transformation for all elements.
