PipelineComponent.ProcessInput Method

Called at run time when a PipelineBuffer from an upstream component is available to the component to let the component process the incoming rows.

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

public virtual void ProcessInput (
	int inputID,
	PipelineBuffer buffer
)
public void ProcessInput (
	int inputID, 
	PipelineBuffer buffer
)
public function ProcessInput (
	inputID : int, 
	buffer : PipelineBuffer
)

Parameters

inputID

The ID of the input of the component.

buffer

The PipelineBuffer object.

The ProcessInput method is called to provide the component a full PipelineBuffer object that contains rows from the upstream component. The columns contained in buffer include those columns defined in the IDTSInputColumnCollection90 of the component. If the component has synchronous outputs, the buffer will also include the columns added to the output column collection by the component, and all the columns in the output column collection of the components upstream from the component. Columns are located in a buffer row using the FindColumnByLineageID method of the BufferManager.

ProcessInput will be called repeatedly as the data flow task receives full buffers from the upstream components. The final call to ProcessInput is confirmed when the EndOfRowset property is true.


public override void ProcessInput( int inputID, PipelineBuffer buffer )
{
    if( !buffer.EndOfRowset)
    {
        while( buffer.NextRow() )
        {
            // TODO: Read or write data to the columns in the buffer.
        }
    }
}
