Saving and Loading Settings of Objects Tree Workbook

A time series database workbook enables the user to load and save its settings and settings for indicators tree.

The following settings are saved and loaded:

Attributes and their order.
Filtering parameters for each attribute.
The sort order for each attribute.
Names of levels for attribute dimensions.
Determined alternate hierarchy.
Parameters of the Calculation Results panel.

Settings are saved only for the time series databases, which series are used in the workbook.

Example description

Executing the example requires a form with the following components:

The Save button with the SaveButton identifier.
The Load button with the LoadButton identifier.
The LanerBox component.
The LanerResultsBox component.
The UiErAnalyzer component with the UiErAnalyzer1 identifier. The selected component contains a workbook of time series database that is a data source of the LanerBox and LanerResultsBox components.
The MetaAttributesBreadcrumb component with the MetaAttributesBreadcrumb1 identifier. This component must use the same time series database as workbook that is loaded to UiErAnalyzer1.
The MetaAttributesTreeList component connected with MetaAttributesBreadcrumb1.

Add links to the Metabase, Express, Xml and Cubes system assemblies.

The workbook settings are saved by clicking the Save button and loaded by clicking the Load button.

Save settings procedure

This procedure is a handler of the OnClick event for the SaveButton button.

Sub SaveButtonOnClick(Sender: Object; Args: IMouseEventArgs);
Var
    Doc: FreeThreadedDOMDocument60;
    Element: IXmlDomElement;
    Ea: IEaxAnalyzer;
    Wb: IEaxWorkbook;
    WbTree: IEaxWorkbookMetaAttributesTree;
    Rub: IRubricator;
    OpList: IEaxWorkbookRubricatorOptionsList;
    Options: IEaxWorkbookRubricatorOptions;
    Statistics: IEaxWorkbookStatistics;
Begin
    // Save the MetaAttributesBreadcrumb1 settings to XML
    Doc := New FreeThreadedDOMDocument60.Create;
    Element := Doc.createElement("Breadcrumb");
    MetaAttributesBreadcrumb1.SaveState(Element);
    Doc.appendChild(Element);
    // Get workbook
    Ea := UiErAnalyzer1.ErAnalyzer;
    Wb := Ea As IEaxWorkbook;
    // Get object tree parameters
    WbTree := Wb.MetaAttributesTree;
    Rub := MetaAttributesBreadcrumb1.Rubricator.Rubricator;
    // Get directory settings, connected to the object tree
    OpList := WbTree.RubricatorsOptions;
    // Clear settings
    OpList.Clear;
    If Options = Null Then
        Options := OpList.Add(Rub As IMetabaseObjectDescriptor);
        Debug.WriteLine(Time series database:  + Options.RubricatorObject.Name);
    End If;
    // Set indicators tree parameters
    Options.HierarchyAttributes := Doc.xml;
    // Set settings for the Calculation results panel
    Statistics := Wb.Statistics;
    Statistics.Enabled := True;
    Statistics.Visible := False;
    // Save workbook
    (Ea As IMetabaseObject).Save;
End Sub SaveButtonOnClick;

All settings, specified for the workbook that is loaded to LanerBox, are saved after executing the example.

Load Settings Procedure

This procedure is a handler of the OnClick event for the LoadButton button.

Sub LoadButtonOnClick(Sender: Object; Args: IMouseEventArgs);
Var
    Rub: IRubricator;
    RubKey: Integer;
    Doc: FreeThreadedDOMDocument60;
    Element: IXmlDomElement;
    Ea: IEaxAnalyzer;
    Wb: IEaxWorkbook;
    WbTree: IEaxWorkbookMetaAttributesTree;
    OpList: IEaxWorkbookRubricatorOptionsList;
    Options: IEaxWorkbookRubricatorOptions;
Begin
    // Get time series,
    // linked with MetaAttributesBreadcrumb1
    Rub := MetaAttributesBreadcrumb1.Rubricator.Rubricator;
    RubKey := (Rub As IMetabaseObjectDescriptor).Key;
    // Get workbook
    Ea := UiErAnalyzer1.ErAnalyzer;
    Wb := Ea As IEaxWorkbook;
    // Get object tree parameters
    WbTree := Wb.MetaAttributesTree;
    // Get directory settings, connected to the object tree
    OpList := WbTree.RubricatorsOptions;
    Options := OpList.Item(RubKey);
    // Load saved settings from the workbook MetaAttributesBreadcrumb1
    If Options <> Null Then
        Doc := New FreeThreadedDOMDocument60.Create;
        If (Doc.loadXML(Options.HierarchyAttributes)) Then
            Element := Doc.selectSingleNode("Breadcrumb") As IXmlDomElement;
            If (Element <> Null) Then
                MetaAttributesBreadcrumb1.LoadState(Element);
            End If;
        Else
            Debug.WriteLine(Error loading an XML);
        End If;
    End If;
    // Load saved setting from the workbook of the Calculation Results panel
    LanerResultsBox1.ContainerVisible(LanerBoxContainerType.Results) := Wb.Statistics.Visible;
End Sub LoadButtonOnClick;

After executing the example, all saved settings are loaded for the workbook loaded to LanerBox.
