주의

The ScriptBuffer class serves as the base class for the read-only classes representing the input and the outputs that are generated by the Script component in the BufferWrapper project item in a Script component project. The classes in the BufferWrapper project item provide the developer with a set of methods for working with the data flow buffers, as well as typed accessor properties for each column in the buffers.

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.

예제

The following code sample from 스크립트 구성 요소를 사용하여 비동기 변환 만들기 demonstrates several methods and properties of the ScriptBuffer class, including AddRow, NextRow, EndOfRowset, and SetEndOfRowset.

Public Class ScriptMain
    Inherits UserComponent

    Private myRedmondAddressCount As Integer

    Public Overrides Sub CreateNewOutputRows()

        MySummaryOutputBuffer.AddRow()

    End Sub

    Public Overrides Sub MyAddressInput_ProcessInput(ByVal Buffer As MyAddressInputBuffer)

        While Buffer.NextRow()
            MyAddressInput_ProcessInputRow(Buffer)
        End While

        If Buffer.EndOfRowset Then
            MyAddressOutputBuffer.SetEndOfRowset()
            MySummaryOutputBuffer.MyRedmondCount = myRedmondAddressCount
            MySummaryOutputBuffer.SetEndOfRowset()
        End If

    End Sub

    Public Overrides Sub MyAddressInput_ProcessInputRow(ByVal Row As MyAddressInputBuffer)

        With MyAddressOutputBuffer
            .AddRow()
            .AddressID = Row.AddressID
            .City = Row.City
        End With

        If Row.City.ToUpper = "REDMOND" Then
            myRedmondAddressCount += 1
        End If

    End Sub

End Class
