Comentários

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.
