IAlgorithmCalculationResult.HasError

Syntax

HasError: Boolean;

Description

The HasError property returns whether errors occurred on algorithm calculation.

Comments

Available values:

The list of error messages is set using the IMsProblemCalculationCallback.OnError method.

Example

Executing the example requires that the repository contains a ready calculation algorithm with the ALGORITHM identifier. The calculation algorithm should contain configured objects.

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

Sub UserProc;
Var
    MB: IMetabase;
    MObj: IMetabaseObjectDescriptor;
    Algo: ICalcObject;
    CalcAlgo: ICalcAlgorithm;
    CalcResult: IAlgorithmCalculationResult;
    i: Integer;
    Errors: IStringList;
    Error: String;
Begin
    MB := MetabaseClass.Active;
    // Get calculation algorithm
    MObj := MB.ItemById("ALGORITHM");
    Algo := CalcObjectFactory.CreateCalcObject(MObj, True);
    CalcAlgo := Algo As ICalcAlgorithm;
    // Calculate algorithm
    CalcResult := CalcAlgo.Calculate;
    // Check if there are errors on algorithm calculation
    If CalcResult.HasError Then
        Errors := CalcResult.Errors;
        For i := 0 To Errors.Count-1 Do
            Error := Errors.Item(i);
            // Display error message in the console
            Debug.WriteLine(Error);
        End For;
    End If;
End Sub UserProc;

After executing the example, the calculation algorithm is calculated. If errors occurred in calculation, the console displays error messages.
