Public ReadOnly Property Buffer As Integer

Property Value

Int32

The integer ID of the PipelineBuffer assigned to the IDTSOutput100 object.

Attributes: ComAliasNameAttribute DispIdAttribute

Examples

The following code example locates the output columns in a buffer using FindColumnByLineageID. The indexes of the columns are stored in an internal member array so they can be accessed using either the PrimeOutput method or the ProcessInput method.

int []columnIndex;  
public override void PreExecute()  
{  
    IDTSOutput100 output = ComponentMetaData.OutputCollection[0];  

    columnIndex = new int[output.OutputColumnCollection.Count];  

    for(int x=0; x< output.OutputColumnCollection.Count; x++)  
    {  
        IDTSOutputColumn100 col = output.OutputColumnCollection[x];  
        columnIndex[x] = BufferManager.FindColumnByLineageID( output.Buffer,col.LineageID);  
    }  
}

Private columnIndex As Integer()   

Public  Overrides Sub PreExecute()   
 Dim output As IDTSOutput100 = ComponentMetaData.OutputCollection(0)   
 columnIndex = New Integer(output.OutputColumnCollection.Count - 1) {}   
 Dim x As Integer = 0   
 While x < output.OutputColumnCollection.Count   
   Dim col As IDTSOutputColumn100 = output.OutputColumnCollection(x)   
   columnIndex(x) = BufferManager.FindColumnByLineageID(output.Buffer, col.LineageID)   
   x -= 1   
 End While   
End Sub

Remarks

This run-time property is primarily used as a parameter for the FindColumnByLineageID method of the BufferManager property to locate a column in a PipelineBuffer.
