ICubeMetaLoader.LoadEmptyValues

Fore Syntax

LoadEmptyValues: Boolean;

Fore.NET Syntax

LoadEmptyValues: boolean;

Description

The LoadEmptyValues property determines whether to load empty values of time series.

Comments

Available values:

True. Empty values of time series are loaded to the database.
False. Default value. Empty values of time series are not imported.

Fore Example

Executing the example requires that the repository contains a time series database with the TSBD identifier. The database contains an import object with the OBJ_IMPORT identifier that imports data from all sources except for time series databases.

Add links to the Cubes and Metabase system assemblies.

Sub UserProc;
Var
    Metabase: IMetabase;
    RubrDescr: IMetabaseObjectDescriptor;
    ImpRequestDef: IImportRequestDefinition;
    MetaLoader: ICubeMetaLoader;
Begin
    Metabase := MetabaseClass.Active;
    RubrDescr := Metabase.ItemById("TSDB");
    // Get import object
    ImpRequestDef := Metabase.ItemByIdNamespace("OBJ_IMPORT", RubrDescr.Key).Edit As IImportRequestDefinition;
    MetaLoader := ImpRequestDef.ProviderParams As ICubeMetaLoader;
    // Set up parameters empty value loading
    MetaLoader.LoadEmptyValues := True;
    (ImpRequestDef As IMetabaseObject).Save;
End Sub UserProc;

After executing the example import object parameters are changed: empty values are imported to the time series database.

Fore.NET Example

The requirements and result of the Fore.NET example execution match with those in the Fore example.

Imports Prognoz.Platform.Interop.Metabase;
Imports Prognoz.Platform.Interop.Cubes;
…
Public Shared Sub Main(Params: StartParams);
Var
    Metabase: IMetabase;
    RubrDescr: IMetabaseObjectDescriptor;
    ImpRequestDef: IImportRequestDefinition;
    MetaLoader: ICubeMetaLoader;
Begin
    Metabase := Params.Metabase;
    RubrDescr := Metabase.ItemById["TSDB"];
    // Get import object
    ImpRequestDef := Metabase.ItemByIdNamespace["OBJ_IMPORT", RubrDescr.Key].Edit() As IImportRequestDefinition;
    MetaLoader := ImpRequestDef.ProviderParams As ICubeMetaLoader;
    // Set up parameters empty value loading
    MetaLoader.LoadEmptyValues := True;
    (ImpRequestDef As IMetabaseObject).Save();
End Sub;
