備註
This method is called when a data flow component has finished reading or writing data in the IDTSBuffer90. In low memory situations, the IDTSBufferManager90 may swap unlocked buffers from memory to disk.
Managed component developers do not need to call this method because the managed PipelineBuffer object automatically locks and unlocks itself.
