ICubeInstanceDestination.FlushCache

Fore Syntax

FlushCache;

Fore.NET Syntax

FlushCache();

Description

The FlushCache method clears cache of the opened cube instance.

Comments

Caching provides a possibility to reduce loading time and provides quicker access to some data. If source data does not correspond to cached data, the cache clearing is required.

Fore Example

To execute the example, add links to the Metabase and Cubes system assemblies. A cube with the CUBE_WDI identifier is supposed to be in the repository.

Sub  UserProc;
Var
    MB: IMetabase;
    CubeInst: ICubeInstance;
    CubeInstDest: ICubeInstanceDestination;
Begin
    MB := MetabaseClass.Active;
    CubeInst := MB.ItemById("CUBE_WDI").Open(Null) As  ICubeInstance;
    CubeInstDest := CubeInst.Destinations.DefaultDestination;
    CubeInstDest.UpdateCache;
    Debug.WriteLine(CubeInstDest.Cached);
    CubeInstDest.FlushCache;
    Debug.WriteLine(CubeInstDest.Cached);
End  Sub  UserProc;

After executing the example the cache of the cube with the CUBE_WDI identifier will be cleared.

Fore.NET Example

Imports System;
Imports Prognoz.Platform.Interop.Metabase;
Imports Prognoz.Platform.Interop.Cubes;

Public Shared Sub Main(Params: StartParams);
Var
    MB: IMetabase;
    CubeInst: ICubeInstance;
    CubeInstDest: ICubeInstanceDestination;
Begin
    MB := Params.Metabase;
    CubeInst := MB.ItemById["CUBE_WDI"].Open(Null) As ICubeInstance;
    CubeInstDest := CubeInst.Destinations.DefaultDestination;
    CubeInstDest.UpdateCache();
    System.Diagnostics.Debug.WriteLine(CubeInstDest.Cached);
    CubeInstDest.FlushCache();
    System.Diagnostics.Debug.WriteLine(CubeInstDest.Cached);
End Sub;

The result of executing the example matches with that of the Fore example.
