IEaxAnalyzeCore.OpenMatrixDataSource

Syntax

OpenMatrixDataSource(DataSource: IMatrixDataSource);

Parameters

DataSource - an abstract multidimensional data source, which data should be loaded to the express report.

Description

The OpenMatrixDataSource property loads data to the express report from a non-cube source.

For example, data of modeling variables obtained as a result of a modeling problem calculation can be used as a non-cube source. Access to data variables is executed by means of the VariableStub property.

Example

Executing the example requires a form, a button named Button1 on the form, the UiErAnalyzer component named UiErAnalyzer1 and some components that show data of the express report loaded to UiErAnalyzer1. The repository should contain a modeling container with the KONT_MODEL identifier. This container contains the Problem_1 modeling problem configured to calculate models.

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

Var

MB: IMetabase;

CrInfo: IMetabaseObjectCreateInfo;

Expr: IEaxAnalyzer;

Problem: IMsProblem;

Setting: IMsProblemCalculationSettings;

Calc: IMsProblemCalculation;

MDS: IMatrixDataSource;

Begin

//Temporary express report

MB := MetabaseClass.Active;

CrInfo := MB.CreateCreateInfo;

CrInfo.ClassID := MetabaseObjectClass.KE_CLASS_EXPRESSREPORT;

Expr := MB.CreateObject(CrInfo).Edit As IEaxAnalyzer;

//Calculated modeling problem

Problem := MB.ItemByIdNamespace("Problem_1", MB.ItemById("KONT_MODEL").Key).Bind As IMsProblem;

Setting := Problem.CreateCalculationSettings;

//Calculate modeling problem

Calc := Problem.Calculate(Setting);

//Data on the first output variable

MDS := Calc.VariableStub(Problem.VariableStubs(MsVariableKind.Output).Item(0));

//Load to express report

Expr.OpenMatrixDataSource(MDS);

//Load express report to "UiErAnalyzer1"

UiErAnalyzer1.ErAnalyzer := Expr;

UiErAnalyzer1.Active := True;

End Sub Button1OnClick;

After executing the example the Problem_1 modeling problem is calculated. Report on the first output variable is loaded to the UiErAnalyzer1 component. Data is displayed in all components using UiErAnalyzer1 as a data source.
