PipelineComponent Class

Defines the base class that is used when developing managed data flow components.

Namespace: Microsoft.SqlServer.Dts.Pipeline
Assembly: Microsoft.SqlServer.PipelineHost (in microsoft.sqlserver.pipelinehost.dll)

Syntax

'Declaration
Public Class PipelineComponent
public class PipelineComponent
public ref class PipelineComponent
public class PipelineComponent
public class PipelineComponent

Remarks

Inherit from this class to create your own data flow component. This class implements the required component interfaces, IDTSDesigntimeComponent90 and IDTSRuntimeComponent90. You override the base class implementation of these methods to provide the functionality of your component. PipelineComponent provides helper methods in addition to the methods of the component interfaces to help you in developing your component.

Example

The following code example shows a component that implements the DtsPipelineComponentAttribute and inherits from the PipelineComponent class.

using System;
using Microsoft.SqlServer.Dts.Pipeline.Wrapper;
namespace Microsoft.Samples.SqlServer.Dts
{
    [DtsPipelineComponent(DisplayName="SampleComponent")]
    public class SampleComponent : PipelineComponent
    {
        public override ProvideComponentProperties()
        {
            // TODO: Implement component intialization.
        }
        public override DTSValidationStatus Validate()
        {
            // TODO: Implement component validation.
        }
        public override void ProcessInput( int inputID, PipelineBuffer buffer)
        {
            // TODO: For transformation and destination components,
            //  implement code to process incoming rows.
        }
    }
}
Imports System 
Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper 
Namespace Microsoft.Samples.SqlServer.Dts 

 <DtsPipelineComponent(DisplayName="SampleComponent")> _ 
 Public Class SampleComponent 
 Inherits PipelineComponent 

   Public Overrides Sub ProvideComponentProperties() 
    ' TODO: Implement component intialization.
   End Sub 

   Public Overrides Function Validate() As DTSValidationStatus 
    ' TODO: Implement component validation.
   End Function 

   Public Overrides Sub ProcessInput(ByVal inputID As Integer, ByVal buffer As PipelineBuffer) 
    ' TODO: For transformation and destination components,
    '  implement code to process incoming rows.
   End Sub 
 End Class 
End Namespace
