IMatrixModel.LowerBoundI

Syntax

LowerBoundI(DimIndex: Integer): Integer;

Parameters

DimIndex. Number of the dimension, the lower limit of which must be obtained.

Description

The LowerBoundI property returns the lower limit of the dimension, which number is passed as an input parameter.

Comments

The difference between the LowerBoundI property and the LowerBound property is its internal implementation, in which work with data is optimized, which, in turn, speeds up work and saves memory when large-sized matrixes are used.

Example

Executing the example requires that the repository contains a cube with the STD_CUBE identifier.

Add links to the Cubes, Dimensions, Matrix, Metabase system assemblies.

Sub UserProc;
Var
    MB: IMetabase;
    CubeInst: ICubeInstance;
    MDS: IMatrixDataSource;
    DSS: IDimSelectionSet;
    M: IMatrix;
    i: Integer;
Begin
    MB := MetabaseClass.Active;
    // Open cube
    CubeInst := MB.ItemById("STD_CUBE").Open(Null) As ICubeInstance;
    MDS := CubeInst.Destinations.DefaultDestination As IMatrixDataSource;
    // Create selection , by which matrix with data will be obtained
    DSS := MDS.CreateDimSelectionSet;
    For i := 0 To DSS.Count - 1 Do
        DSS.Item(i).SelectAll;
    End For;
    // Calculate output cube matrix
    M := MDS.Execute(DSS);
    // View information about matrix dimensions
    For i := 0 To M.DimensionCount - 1 Do
        Debug.Write("Dimension No.: " + i.ToString);
        Debug.Write("; Lower limit: " + M.LowerBoundI(i).ToString);
        Debug.WriteLine("; Upper limit: " + M.UpperBoundI(i).ToString);
    End For;
End Sub UserProc;

After executing the example a matrix with data is created on the basis of a cube. The lower and upper limits by all the dimensions of the output matrix will be displayed in the console.
