IMetaMembersSet.CurrentOffset

Syntax

CurrentOffset: Integer;

Description

The CurrentOffset property returns the number of hierarchy levels from dictionary root to elements set.

Comments

To get current element in the set, use the IMetaMembersSet.Current method.

Example

Executing the example requires a time series database with the TSDB identifier.

Add links to the Cubes, Metabase, Rds system assemblies.

Sub UserProc;
Var
    MB: IMetabase;
    Rubr: IMetabaseObject;
    RubrInst: IRubricatorInstance;
    Facts: IMetaDictionaryInstance;
    Hierarchy: IMetaHierarchy;
    HInstance: IMetaHierarchyInstance;
    Members: IMetaMembers;
Begin
    MB := MetabaseClass.Active;
    Rubr := MB.ItemById("TSDB").Bind;
    RubrInst := Rubr.Open(Null) As IRubricatorInstance;
    Facts := RubrInst.GetDictionary(RubricatorDictionary.Facts);
    Hierarchy := Facts.Dictionary.DefaultHierarchy;
    HInstance := Facts.OpenHierarchy(Hierarchy);
    Members := HInstance.GetRootMembers;
    Members.Reset;
    Debug.WriteLine("Number of hierarchy levels: " + Members.CurrentOffset.ToString);
    Debug.WriteLine("Names of root elements in the hierarchy:");
    Debug.Indent;
    While Not Members.Eof Do
        Debug.WriteLine(Members.Current.Name);
        Members.Next;
    End While;
    Debug.Unindent;
End Sub UserProc;

After executing the example the console displays the following:

Number of hierarchy levels.
Name of root elements in factors hierarchy.
