ILaner.SaveProblem

Syntax

SaveProblem(SerieIndices: Array): IMetabaseObjectDescriptor;

Parameters

SerieIndices. Indexes of saved series given as an array. If the parameter is set to Null, all series will be saved.

Description

The SaveProblem method saves working area data as a modeling problem.

Comments

Saving a data table in the form of a modeling problem is relevant only if the table contains calculated series. Otherwise the empty problem is saved. The problem is saved to the child object of the time series database: that is, the Transformations modeling container. During saving the following objects are created:

Modeling variable - the modeling variables are created based on the calculated series, for which the original series (indicators) are the input (explanatory) variables.
Model - describes the transformation of the modeling variable.
Metamodel - describes the model calculation sequence.
Problem - forms the metamodel manipulation problem.

Example

Executing the example requires a form with the following components: the Button component named Button1, the TabSheetBox component named TabSheetBox1, and the UiErAnalyzer component named UiErAnalyzer1. UiErAnalyzer1 is a data source for TabSheetBox1. A working area of the time series database should be loaded to UiErAnalyzer1.

The example is a handler of the OnClick event for the Button1 component.

Add links to the Express, ExtCtrls, Forms, Laner, Metabase and Tab system assemblies.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    ErA: IEaxAnalyzer;
    Laner: ILaner;
    ar: Array[1] Of Integer;
    ProblDesc: IMetabaseObjectDescriptor;
Begin
    ErA := UiErAnalyzer1.ErAnalyzer;
    Laner := ErA.Laner;
    ar[0] := 0;
    ProblDesc := Laner.SaveProblem(ar);
    Debug.WriteLine(ProblDesc.Name);
End Sub Button1OnClick;

After executing the example the first data series is saved as the modeling problem. The problem name is displayed in the console window.
