IMetaAttribute.Predefined

Syntax

Predefined: Boolean;

Description

The Predefined property returns whether the attribute is a system one.

Comments

The property returns True if an attribute is a system one, and False if an attribute is custom.

Comments

This property can return incorrect result for old versions of system dictionaries of time series database. It is necessary to call the IRubricator.AlterAndSave method to receive correct data before using the Predefined property.

Example

Executing the example requires that the repository contains a time series database with the OBJ_FC identifier.

Sub UserProc;
Var
    MB: IMetabase;
    RubDesc: IMetabaseObjectDescriptor;
    Rubr: IRubricator;
    Attributes: IMetaAttributes;
    Attr: IMetaAttribute;
    i: Integer;
Begin
    MB := MetabaseClass.Active;
    RubDesc := MB.ItemById("OBJ_FC");
    Rubr := RubDesc.Bind As IRubricator;
    Attributes := Rubr.Facts.Attributes;
    For i := 0 To Attributes.Count - 1 Do
        Attr := Attributes.Item(i);
        If Attr.Predefined Then
            Debug.WriteLine(Attribute ' + Attr.Name + ' is system);
        Else
            Debug.WriteLine(Attribute ' + Attr.Name + ' is custom);
        End If;
    End For;
End Sub UserProc;

After executing the example, the console window displays information on the attributes of the database time series.
