IMsProblem.Convert

Syntax

Parameters

format. Required metamodel format.

Description

The Convert method transforms the metamodel calculated by a problem into an internal one without use of objects, and vice versa.

Comments

By default, problems created in the desktop application use a metamodel that is a separate repository object, and problems created in the web application use internal metamodels that are not separate repository objects.

Example

Executing the example requires that the repository contains a modeling container with the MS identifier containing a model with the MODEL_LINEARREGR identifier.

Add links to the Metabase and Ms system assemblies.

Sub UserProc;
Var
    mb: IMetabase;
    Ms: IMetabaseObjectDescriptor;
    CreateInfo: IMetabaseObjectCreateInfo;
    Problem: IMsProblem;
    Model: IMsModel;
    MetaModel: IMsMetaModel;
    CalcChain: IMsCalculationChainEntries;
Begin
    // Get repository
    Mb := MetabaseClass.Active;
    // Get modeling container
    Ms := mb.ItemById("MS");
    // Create a modeling problem
    CreateInfo := Mb.CreateCreateInfo;
    CreateInfo.ClassId := MetabaseObjectClass.KE_CLASS_MSPROBLEM;
    CreateInfo.Parent := Ms;
    CreateInfo.Permanent := True;
    CreateInfo.Id := Mb.GenerateId("PROBLEM_META", Ms.Key);
    CreateInfo.Name := "Problem with internal metamodel";
    Problem := Mb.CreateObject(CreateInfo).Edit As IMsProblem;
    // Transform problem
    Problem.Convert(MsModelFormat.WithoutObject);
    // Create an internal metamodel
    MetaModel := Problem.CreateMetaModel;
    // Get metamodel calculation chain
    CalcChain := MetaModel.CalculationChain;
    // Get model
    Model := mb.ItemByIdNamespace("MODEL_LINEARREGR", Ms.Key).Edit As IMsModel;
    // Add obtained model to calculation chain
    CalcChain.AddModel(Model);
    // Save changes
    (Problem As IMetabaseObject).Save;
End Sub UserProc;

After executing the example a problem that contains internal metamodel is created in the modeling container.
