protected PTFPartition	NoopWithMap._transformRawInput(PTFPartition iPart)
abstract int	ValueBoundaryScanner.computeEnd(int rowIdx, PTFPartition p)
abstract int	ValueBoundaryScanner.computeStart(int rowIdx, PTFPartition p)
protected Object	ValueBoundaryScanner.computeValueUseCache(int r, PTFPartition p) Uses cache to lookup row value.
