ICubeCombinedExecutor.AddCube

Syntax

AddCube(Cube: ICubeInstance; Selection: IDimSelectionSet);

Parameters

Cube. The opened cube instance that must be added for calculation.

Selection. The dimension selection, according to which calculation is executed.

Description

The AddCube method adds a cube to the list for parallel calculation.

Comments

The cube must meet the requirements presented in description of the ICubeCombinedExecutor interface.

Example

Executing the example requires that the repository contains two standard cubes with the STD_CUBE1 and STD_CUBE2 identifiers. Cube settings meet the specified requirements. Each cube contains three dimensions.

Executing the example calculates two cubes at the same time. Calculation results are displayed in the development environment console.
