GetCubeModelDesc Command

Purpose

It determines a time series database or a cube that contain a modeling object.

Parameters of Use

Command parameters are passed in the IUiCommandExecutionContext.Data property. Executing the command requires to specify the following value in this property:

Value type Description
IMetabaseObjectDescriptor Repository object.

Application Features

The command returns both any types of cubes and time series databases.

Example

Executing the example requires a form containing a button named Button1 and the UiModel component named UiModel1.

It is required that the repository contains a time series database that includes a modeling container with a model. This model is specified as an object for the UiModel component.

Add links to the Fore, KeFore, Metabase, Ms, UI system assemblies.

The example is a handler of the OnClick event for the Button1 button.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    Result: IMetabaseObjectDescriptor;
    Key: Integer;
Begin
    Key := UiModel1.Object.Key;
    // Execute function
    Result := GetSmhDesc(Key, "GetCubeModelDesc");
    // Display value
    WinApplication.InformationBox(Result.Name + " (" + Result.Id + ")");
End Sub Button1OnClick;

Function GetSmhDesc(Key: Integer; Plugin: String): IMetabaseObjectDescriptor;
Var
    Desc, Result: IMetabaseObjectDescriptor;
    Target: IUiCommandTarget;
    Context: IUiCommandExecutionContext;
Begin
    Desc := MetabaseClass.Active.Item(Key);
    // Get Ms plugin
    Target := WinApplication.Instance.GetPluginTarget("Ms");
    // Create a context to execute a command
    Context := Target.CreateExecutionContext;
    // Send command parameter
    Context.Data := Desc;
    // Execute the command
    Result := Target.Execute(Plugin, Context) As IMetabaseObjectDescriptor;
    Return Result;
End Function GetSmhDesc;

    // Execute function

    // Display value
    WinApp.InformationBox(Result.Name + " (" + Result.Id + ")", New IWin32WindowForeAdapter(Self));
End Sub;

Function GetSmhDesc(Key: uinteger; Plugin: String): IMetabaseObjectDescriptor;
Var
    Mb: IMetabase;
    Desc, Result: IMetabaseObjectDescriptor;
    Target: IUiCommandTarget;
    Context: IUiCommandExecutionContext;
    WinApp: WinApplicationClassClass = New WinApplicationClassClass();
    RunContext: ForeRuntimeContext;
Begin
    // Get current repository
    Mb := Self.Metabase;
    Desc := Mb.Item[Key];
    // Get Ms plugin
    RunContext := (Mb As IForeServices).GetRuntime().Context;
    Target := WinApp.Instance[RunContext].GetPluginTarget("Ms");
    // Create a context to execute a command
    Context := Target.CreateExecutionContext();
    // Send command parameter
    Context.Data := Desc;
    // Execute the command
    Result := Target.Execute(Plugin, Context, RunContext) As IMetabaseObjectDescriptor;
    Return Result;
End Function GetSmhDesc;

After executing the example, clicking the Button1 button displays a message with information about name and identifier of the time series database that contains a modeling container with the specified model.
