virtual void getComplexV(uInt rownr, Complex *dataPtr)
std::complex< Double > DComplex
VirtualTaQLColumn & operator=(const VirtualTaQLColumn &)
Assignment is not needed and therefore forbidden (so it is made private).
VirtualTaQLColumn(const VirtualTaQLColumn &)
Copy is not needed and therefore forbidden (so it is made private).
virtual void getIntV(uInt rownr, Int *dataPtr)
