Comentários

The ScriptComponent class serves as the base class for the read-only UserComponent class, which is generated by the Script component in the ComponentWrapper project item in a Script component project. The UserComponent class serves as the base class for the ScriptMain class, in which the developer writes custom code, and provides the developer with a set of methods for working with the component's inputs and outputs. It also provides strongly-typed accessor properties for variables and connection managers available to the component.

The Script component developer does not use the ScriptComponent class directly, but indirectly, by coding the methods and properties of the ScriptMain class, which inherits from ScriptComponent through the UserComponent class.

Exemplos

The following code sample demonstrates all the code that a developer has to write to create a transformation with synchronous outputs by using the Script component. For more information on this sample, see Criando uma transformação síncrona com o componente Script.

Public Class ScriptMain
    Inherits UserComponent

    Public Overrides Sub MyAddressInput_ProcessInputRow(ByVal Row As MyAddressInputBuffer)

        Row.City = UCase(Row.City)

    End Sub

End Class
