◆ FillNtupleFromStream()

template<class DataType , class Tuple >

Long64_t ROOT::TreeUtils::FillNtupleFromStream	(	std::istream &	inputStream,
		Tuple &	tuple,
		char	delimiter,
		bool	strictMode
	)

Function to fill tuples (TNtuple/TNtupleD) from a simple ASCII data file.

With auto and decltype - we can get rid of DataType parameter :) (or with a simple typedef inside ntuple class). An input file consists of non-empty lines (separated by newline-characters), possibly empty lines, and comments (treated as empty lines). Each non-empty line should contain N numbers - entry for a tuple. Non-strict mode lets you to have newline-characters inside a tuple's row (as it worked in ROOT prior to v5.3xxx).
