Значение свойства

The IDTSBufferManager90 object.

Замечания

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 IDTSInputColumnCollection90 or IDTSOutputColumnCollection90 of the component, in the PipelineBuffer. This is necessary because the number of columns contained in the IDTSBuffer90 may exceed the number of columns expected by the component.

The BufferManager is also used to create new IDTSBuffer90 objects using the CreateBuffer, CreateFlatBuffer, and CreateVirtualBuffer methods.
