ILanerCalculateSerie.SourceStub

Syntax

SourceStub: IVariableStub;

Description

The SourceStub property returns the data of the series as of an abstract data source.The property returns Null if the series does not have the (ILanerCalculateSerie.Source) source.

Example

Executing the example requires a form with the Button1 button, the TabSheetBox component and the UiErAnalyzer component named UiErAnalyzer1 which is used as a data source for TabSheetBox. Workbook of the time series database must be loaded to UiErAnalyzer1.

Click the button to start executing this example.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);

Var

ErAn: IEaxAnalyzer;

Laner: ILaner;

Series: ILanerSeries;

CalcSerie, Serie: ILanerCalculateSerie;

tr: IMsFormulaTransform;

OutVar, InpVar: IMsFormulaTransformVariable;

Slice: IMsFormulaTransformSlice;

Selector: IMsFormulaTransformSelector;

Formula: IMsFormula;

Determ: IMsDeterministicTransform;

TermInfo: IMsFormulaTermInfo;

Begin

ErAn := UiErAnalyzer1.ErAnalyzer;

Laner := ErAn.Laner;

Laner.BeginUpdate;

Series := Laner.Series;

CalcSerie := Series.Item(0) As ILanerCalculateSerie;

Serie := Series.AddCalculateSerieAsSource(CalcSerie.Source);

Serie.Name := Serie.SourceStub.Name + " + 10";

Serie.UseTransform := True;

tr := Serie.Transform.Transform As IMsFormulaTransform;

OutVar := tr.Outputs.Item(0);

Slice := OutVar.Slices.Add(Null);

Selector := tr.CreateSelector;

Selector.Slice := Slice;

Formula := tr.Transform(Selector);

Formula.Kind := MsFormulaKind.Deterministic;

Determ := Formula.Method As IMsDeterministicTransform;

InpVar := tr.Inputs.Add(Serie.SourceStub);

Slice := InpVar.Slices.Add(Null);

TermInfo := tr.CreateTermInfo;

TermInfo.Slice := Slice;

Determ.Expression.AsString := TermInfo.TermInnerText + " + 10";

Laner.EndUpdate;

End Sub Button1OnClick;

After executing the example the calculated series, that is based on the data of the workbook first series, is added to the workbook.
