Parametri

InputID
The ID of the input to process.

Buffer
A PipelineBuffer that contains the input rows.

Osservazioni

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.

Although the developer can override the ProcessInput method, it is usually sufficient to override the <InputBufferX>_ProcessInputRows method in the ScriptMain class to process data from the input buffers. When additional processing is required, it may be preferable to override the <InputBufferX>_ProcessInput method.

Esempio

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

    Public Overridable Sub Input0_ProcessInput(ByVal Buffer As Input0Buffer)

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

    End Sub
