IMsCalculationChainMetaModel.ResetMetaModel

Fore Syntax

ResetMetaModel;

Fore.NET Syntax

ResetMetaModel();

Description

The ResetMetaModel method resets metamodel in the calculation chain.

Comments

Use the method, if model parameters in repository have been changed and it should be refreshed in the calculation chain.

Fore Example

Executing the example requires that the repository contains a modeling container with the MS identifier. This container must contain metamodel with the CALCULATIONCHAIN identifier calculating metamodel with the METAMODEL_CONVERT identifier in the calculation chain.

Add links to the Metabase, Ms system assemblies.

Sub UserProc;
Var
    mb: IMetabase;
    msKey: Integer;
    MetaModel: IMsMetaModel;
    CalculationChain: IMsCalculationChainEntries;
    ChainMetaModel: IMsCalculationChainMetaModel;
Begin
    // Get current repository
    mb := MetabaseClass.Active;
    // Get modeling container key including metamodel
    msKey := mb.GetObjectKeyById("MS");
    // Get metamodel
    MetaModel := mb.ItemByIdNamespace("CALCULATIONCHAIN", msKey).Edit As IMsMetaModel;
    // Get metamodel calculation chain
    CalculationChain := MetaModel.CalculationChain;
    // Find metamodel by identifier in the calculation chain
    ChainMetaModel := CalculationChain.FindById("METAMODEL_CONVERT") As IMsCalculationChainMetaModel;
    // Reset found metamodel
    ChainMetaModel.ResetMetaModel;
    // Save changes
    (MetaModel As IMetabaseObject).Save;
End Sub UserProc;

After executing the example, the METAMODEL_CONVERT is reset in the calculation chain.

Fore.NET Example

The requirements and result of the Fore.NET example execution match with those in the Fore example.

Imports Prognoz.Platform.Interop.Ms;
…
Public Shared Sub Main(Params: StartParams);
Var
    mb: IMetabase;
    msKey: uinteger;
    MetaModel: IMsMetaModel;
    CalculationChain: IMsCalculationChainEntries;
    ChainMetaModel: IMsCalculationChainMetaModel;
Begin
    // Get current repository
    mb := Params.Metabase;
    // Get modeling container key including metamodel
    msKey := mb.GetObjectKeyById("MS");
    // Get metamodel
    MetaModel := mb.ItemByIdNamespace["CALCULATIONCHAIN", msKey].Edit() As IMsMetaModel;
    // Get metamodel calculation chain
    CalculationChain := MetaModel.CalculationChain;
    // Find metamodel by identifier in the calculation chain
    ChainMetaModel := CalculationChain.FindById("METAMODEL_CONVERT") As IMsCalculationChainMetaModel;
    // Reset found metamodel
    ChainMetaModel.ResetMetaModel();
    // Save changes
    (MetaModel As IMetabaseObject).Save();
End Sub;
