IMsCalculationChainMetaModel.ParamsControl

Syntax

Description

The ParamsControl property returns the collection of controlled parameters of a metamodel included in calculation chain.

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.

Add links to the Metabase and Ms system assemblies.

    pMetaModelParam2.DefaultValue:= 1;

    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;

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.
