IMsProblemCalculation.PointCount

Syntax

PointCount: Integer;

Description

The PointCount property returns the total number of steps passed on modeling problem calculation.

Comments

The property depends on the number of objects used in calculation.

Example

Public Class MCallback: Object, IMsProblemCalculationCallback

Public Calculation: IMsProblemCalculation;

Public Sub OnError(Message: String);

Begin

Debug.WriteLine(Message);

End Sub OnError;

Public Sub OnFinish;

Begin

Debug.WriteLine(The calculation of problem is finished);

Calculation := Null;

End Sub OnFinish;

Public Sub OnMessage(Message: String);

Begin

Debug.Write(DateTime.Now);

Debug.WriteLine(": " + Message);

End Sub OnMessage;

Public Sub OnModelCalculation(Model: IMsModel);

Begin

Debug.WriteLine(Model calculation: + (Model As IMetabaseObject).Id);

End Sub OnModelCalculation;

Public Sub OnStep;

Begin

Debug.WriteLine(Executed steps: + Calculation.PointPassed.ToString + from + Calculation.PointCount.ToString);

End Sub OnStep;

End Class MCallback;

Sub Main;

Var

MB: IMetabase;

MObj: IMetabaseObject;

Problem: IMsProblem;

CallBack: MCallback;

CalcSett: IMsProblemCalculationSettings;

Calculation: IMsProblemCalculation;

Begin

MB := MetabaseClass.Active;

MObj := MB.ItemByIdNamespace("PROBLEM_1", MB.ItemById("KONT_MODEL").Key).Edit;

Problem := MObj As IMsProblem;

CallBack := New MCallback.Create;

CalcSett := Problem.CreateCalculationSettings;

CalcSett.Callback := CallBack;

Calculation := Problem.Calculate(CalcSett);

CallBack.Calculation := Calculation;

Calculation.Run;

MObj.Save;

End Sub Main;

After executing the example the problem with the PROBLEM_1 identifier will be calculated. To track the events that occur during calculation, an object of the MCallback custom class is used. On handling the OnStep event the number of passed calculation steps is displayed in the console.
