IMetaAttributesSet.CreateSubset

Syntax

CreateSubset(Attributes: String; Operation: SubsetOperation): IMetaAttributesSubset;

Parameters

Attributes - attribute identifiers that must be included in a set. Identifiers are enumerated via the sign ;.

Operation - operation of building of attributes set.

Description

The CreateSubset method creates the set of attributes.

Example

Executing the example requires that the repository contains a time series database with the OBJ_FC identifier and an MDM repository with the RDS_REPO identifier. The MDM repository must contain a dictionary with the DICT_CTR identifier.

Sub Main;

Var

MB: IMetabase;

Rubr: IRubricator;

Facts: IMetaDictionary;

Atts: IMetaAttributes;

Attr: IMetaAttribute;

SS: IMetaAttributesSubset;

Rds: IMetabaseObjectDescriptor;

i: Integer;

Begin

MB := MetabaseClass.Active;

Rubr := MB.ItemById("OBJ_FC").Bind As IRubricator;

Facts := Rubr.Facts;

Atts := Facts.Attributes;

SS := Atts.CreateSubset("KEY;REV", SubsetOperation.Select_);

Rds := mb.ItemById("RDS_REPO");

Attr := Atts.FindByValuesObject(MB.GetObjectKeyByIdNamespace("DICT_CTR", Rds.Key));

If Attr <> Null Then

SS.Add(Attr);

End If;

For i := 0 To SS.Count - 1 Do

Debug.WriteLine(SS.Item(i).Name);

End For;

End Sub Main;

After executing the example a set that consists of the attributes KEY and REV is created. If the database time series have an attribute that refers to the DICT_CTR dictionary in the MDM repository, this attribute is also added to the set. Names of all attributes included in the set are displayed in the console window.
