Notas

The Script component developer does not use the ScriptBuffer class directly, but indirectly, through the derived classes in the BufferWrapper project item that represent the component's input and outputs.

If you use only the <InputBufferX>_ProcessInputRow method to loop through rows, then the NextRow method is called for you by the <InputBufferX>_ProcessInput method.

Ejemplos

The following sample code from the autogenerated ComponentWrapper project item demonstrates how the Script component uses the NextRow method.

    Public Overridable Sub Input0_ProcessInput(ByVal Buffer As Input0Buffer)

        While Buffer.NextRow()
            Input0_ProcessInputRow(Buffer)
        End While

    End Sub
