IDTSRuntimeComponent100.BufferManager Property

Sets the IDTSBufferManager100 of a pipeline component.

Namespace:  Microsoft.SqlServer.Dts.Pipeline.Wrapper
Assembly:  Microsoft.SqlServer.DTSPipelineWrap (in Microsoft.SqlServer.DTSPipelineWrap.dll)

Syntax

'Declaration
WriteOnly Property BufferManager As IDTSBufferManager100
    Set
'Usage
Dim instance As IDTSRuntimeComponent100
Dim value As IDTSBufferManager100

instance.BufferManager = value

IDTSBufferManager100 BufferManager { set; }

property IDTSBufferManager100^ BufferManager {
    void set (IDTSBufferManager100^ value);
}

abstract BufferManager : IDTSBufferManager100 with get, set

function set BufferManager (value : IDTSBufferManager100)

Remarks

The BufferManager is a read-only, run-time property that first becomes available to data flow components in the PreExecute method.

The FindColumnByLineageID method is used to locate the columns in the IDTSInputColumnCollection100 or IDTSOutputColumnCollection100 of the component, in the PipelineBuffer. This is necessary because the number of columns contained in the IDTSBuffer100 may exceed the number of columns expected by the component.

The BufferManager is also used to create new IDTSBuffer100 objects using the CreateBuffer, CreateFlatBuffer, and CreateVirtualBuffer methods.
