IDTSOutput100.Buffer Property
Gets the ID of the PipelineBuffer allocated for an IDTSOutput100 object.
Namespace: Microsoft.SqlServer.Dts.Pipeline.Wrapper
Assembly: Microsoft.SqlServer.DTSPipelineWrap (in Microsoft.SqlServer.DTSPipelineWrap.dll)
Syntax
'Declaration
ReadOnly Property Buffer As Integer
Get
'Usage
Dim instance As IDTSOutput100
Dim value As Integer
value = instance.Buffer
int Buffer { get; }
property int Buffer {
int get ();
}
abstract Buffer : int
function get Buffer () : int
Property Value
Type: System.Int32
The integer ID of the PipelineBuffer assigned to the IDTSOutput100 object.
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.
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
