Setting Up Event Handling

To work with the tool in Foresight Analytics Platform 10, use the new interface.

A development environment object and a class containing implementation of event handlers for the ETL task are specified on the Event Handling page.

To open ETL task properties, execute one of the following operations:

Select the Task > Properties item in the ETL task's main menu.
Press CTRL+P.

Click the Next button to go to the Event Handling wizard page.

Select a development environment object in the Unit drop-down list, select a class that contains implementation of event handlers for ETL task in the Class drop-down list. A list of handler classes contains all classes inherited by the EtlTaskExecutionEvents class.

If required, an event handler can be created automatically by clicking the Create button. In this case a Fore unit is created. Unit code is generated automatically and opened in the development environment.

Event handler class can have the designer called at each class initialization. The designer must not contain parameters. If the class has several constructors without parameters, the first one is called (located above the others in the code).

Class EventsClass: EtlTaskExecutionEvents
    Constructor Create;
    Begin

    End Constructor Create;

    Public Sub OnStartTask(Task: IEtlTask);
    Begin
    End Sub OnStartTask;

    Public Sub OnEndTask(Task: IEtlTask; Duration, TotalRec, ErrorRec: Integer);
    Begin
    End Sub OnEndTask;

    Public Sub OnStartBlock(Task: IEtlTask; Object: IEtlObject);
    Begin
    End Sub OnStartBlock;

    Public Sub OnEndBlock(Task: IEtlTask; Object: IEtlObject; Duration: Integer; TotalRecIn, TotalRecOut, ErrorRec: IDictionary);
    Begin
    End Sub OnEndBlock;

    Public Sub OnProgress(Task: IEtlTask; Progress: Integer);
    Begin
    End Sub OnProgress;

    Public Sub OnError(Task: IEtlTask; Object: IEtlObject; Excep: IException);
    Begin
    End Sub OnError;
End Class EventsClass;
