Detailed Description

template<class Ntuple>
class npstat::NtNtupleFill< Ntuple >

This convenience class fills an ntuple using contents of another ntuple

Constructor & Destructor Documentation

NtNtupleFill()

template<class Ntuple >

npstat::NtNtupleFill< Ntuple >::NtNtupleFill ( Ntuple *  destination, const std::vector< unsigned long > &  columnMap  )

The constructor assumes that correctness of the ntuple column numbers has already been verified. Column numbers are thus best generated with AbsNtuple methods "columnIndices". Column number columnMap[0] of the source ntuple (whose "cycleOverRows" method will be called) will be mapped into the first column of the destination ntuple, columnMap[1] into the second, etc. The number of "columnMap" elements must be equal either to the number of columns in the destination ntuple or to zero. In the latter case an automatic trivial sequential column mapping will be generated.
