ICubeMetaUpdateEx.GetStream

Syntax

GetStream(Tag: String): Object;

Parameters

Tag. Stream name.

Description

The GetStream method gets user data stream from the copied time series database.

Example

Executing the example requires an MDM repository with the MDM_REPO identifier, the file C:\Param.zip that contains a copy of the time series database, and the UserStream user-defined stream.

Sub Main;

Var

RubUpdateEx: ICubeMetaUpdateEx;

mb: IMetabase;

rds: IRdsDatabase;

CrInfo: IMetabaseObjectCreateInfo;

s: string;

progress: IMetabaseUpdateProgress;

iis: IIOStream;

Begin

RubUpdateEx := New CubeMetaUpdateClass.Create As ICubeMetaUpdateEx;

mb := MetabaseClass.Active;

RubUpdateEx.Metabase := mb;

rds := mb.ItemById("RDS_REPO").Bind As IRdsDatabase;

RubUpdateEx.RdsDatabase := rds;

RubUpdateEx.Load("C:\Param.zip");

iis := RubUpdateEx.GetStream("UserStream") As IIOStream;

Debug.WriteLine(iis.ReadByte);

CrInfo := RubUpdateEx.CreateInfo;

CrInfo.Parent := mb.Root;

s := Mb.GenerateId("FC_COPY");

CrInfo.Id := s;

CrInfo.Name := s;

RubUpdateEx.Apply(progress);

End Sub Main;

After executing the example a copy of the time series database with the FC_COPY identifier is created in the repository root from the C:\Param.zip file. The first byte of the UserStream user stream saved to the file is displayed in the console window.
