IMsModelParamsControl.Item

Syntax

Item(Index: Integer): IMsModelParamControl;

Parameters

Index. Parameter index in the collection.

Description

The Item method returns parameter from the collection by its index.

Example

Executing the example requires that the repository contains a time series database with the FC_PARAM identifier. The database modeling container contains two metamodels with the METAMODEL and META_CONTROLLED identifiers.

Sub Main;

Var

mb: IMetabase;

Catalog: IRubricator;

Transforms: IMetabaseObjectDescriptor;

MetaModel_1, MetaModel_2: IMsMetaModel;

MMParams: IMsModelParams;

pMetaModelParam1, pMetaModelParam2: IMsModelParam;

MainChainEntries: IMsCalculationChainEntries;

pChain: IMsCalculationChainMetaModel;

ParamsControl: IMsModelParamsControl;

pControl: IMsModelParamControl;

Begin

mb := MetabaseClass.Active;

Catalog := mb.ItemById("FC_PARAM").Bind As IRubricator;

Transforms := Catalog.ModelSpace;

MetaModel_1 := mb.ItemByIdNamespace("METAMODEL", Transforms.Key).Edit As IMsMetaModel;

MMParams := MetaModel_1.Params;

MMParams.Clear;

pMetaModelParam1 := MMParams.Add;

pMetaModelParam1.Name := "Main param";

pMetaModelParam1.Id := "Main_Param";

pMetaModelParam1.Hidden := True;

pMetaModelParam1.DataType := DbDataType.Float;

pMetaModelParam1.DefaultValue := 0.36;

MainChainEntries := MetaModel_1.CalculationChain;

MainChainEntries.Clear;

MetaModel_2 := mb.ItemByIdNamespace("META_CONTROLLED", Transforms.Key).Edit As IMsMetaModel;

MMParams := MetaModel_2.Params;

MMParams.Clear;

pMetaModelParam2 := MMParams.Add;

pMetaModelParam2.Name := "Controlled param";

pMetaModelParam2.Id := "Controlled_param";

pMetaModelParam2.Hidden := True;

pMetaModelParam2.DataType := DbDataType.Integer;

pMetaModelParam2.DefaultValue := 1;

(MetaModel_2 As IMetabaseObject).Save;

pChain := MainChainEntries.AddMetaModel(MetaModel_2);

ParamsControl := pChain.ParamsControl;

pControl := ParamsControl.Item(0);

pControl.ControllingParam := pMetaModelParam1;

pControl.Value := 4;

(MetaModel_1 As IMetabaseObject).Save;

End Sub Main;

After executing the example the parameters are determined for metamodels. The META_CONTROLLED metamodel is included in the chain of the METAMODEL metamodel calculation. The controlled parameter of the calculation chain sets the METAMODEL metamodel parameter, the value is determined for it.
