IOrmConditions.Evaluate

Syntax

Evaluate(Value: IOrmRecord): IOrmCondition;

Parameters

Value. Checked record.

Description

The Evaluate method checks if collection conditions are fulfilled for the specified record.

Comments

If all the conditions are fulfilled for the specified record, the method returns Null. If a condition is not fulfilled, the method returns this condition.

Example

Executing the example requires that the repository contains a dictionary with the Evaluate identifier containing a logical attribute with the IS_ACTUAL identifier.

Add links to the Dimensions, Metabase, and Orm system assemblies.

Sub Evaluate;
Var
    MB: IMetabase;
    pDim: IDimInstance;
    pDimModel: IDimensionModel;
    pManager: IDimOrmManager;
    pClass: IDimOrmClass;
    Conds: IOrmConditions;
    pCond: IDimOrmCondition;
    pCondition, pCond_1: IOrmCondition;
    pDimElement: IDimElement;
    pDimElements: IDimElementArray;
    i, ArttrInd: Integer;
    Record: IOrmRecord;
Begin
    MB := MetabaseClass.Active;
    // Get dictionary
    pDim := MB.ItemById("DICT").Open(Null) As IDimInstance;
    // Get dictionary structure
    pDimModel := pDim.Dimension;
    // Create an object that is used to work with conditions
    pManager := New DimOrmManager.Create;
    // Create a class that is used to work with conditions
    pClass := pManager.CreateClass(pDimModel);
    // Create a condition
    pCond := pClass.CreateCondition;
    Conds := pCond.Conditions;
    pCondition := Conds.Add;
    pCondition.AttributeName := "IS_ACTUAL";
    pCondition.Value := True;
    // Get dictionary elements
    pDimElements := pDim.Elements.Elements;
    // Check whether each element complies with condition
    pDimElement := pDim.NewElement;
    For i := 0 To pDimElements.Count - 1 Do
        pDimElement.Element := pDimElements.Element(i);
        Record := pDimElement As IOrmRecord;
        // Perform check
        pCond_1 := Conds.Evaluate(Record);
        // If element does not comply with condition,
        // display its name
        If pCond_1 <> Null Then
            ArttrInd := Record.FindAttribute("NAME");
            Debug.WriteLine(Record.AttributeValue(ArttrInd));
        End If;
    End For;
End Sub Evaluate;

After executing the example the console window displays names of the elements, which do not comply with the condition: the IS_ACTUAL attribute must be set to True.
