ICalcObject.Params

Syntax

Description

The Params property returns the collection of calculation algorithm object parameters.

Example

Executing the example requires that the repository contains a calculation algorithm with the ALGORITHM identifier. Calculation blocks are created and set up in the calculation algorithm. The repository should also contain a dictionary with the CALENDAR identifier used by calculation block consumer and sources.

Add links to the Algo, Metabase, Ms, Transform system assemblies. Add links to the assemblies required for working with calculation algorithms.

After executing the example, various settings of calculation algorithm and calculation block will be changed:

Object names will be changed.
Parameters will be added to calculation algorithm and calculation blocks structure.
