Detailed Description

template<class V = GslVector, class M = GslMatrix>
class QUESO::AsciiTable< V, M >

Class for reading ASCII values from a table in a file.

Definition at line 45 of file AsciiTable.h.

Constructor & Destructor Documentation

template<class V , class M >

QUESO::AsciiTable< V, M >::AsciiTable	(	const BaseEnvironment &	env,
		unsigned int	numRows,
		unsigned int	numExtraCols,
		const std::vector< bool > *	extraColIsString,
		const std::string &	fileName
	)

Default constructor.

This constructor reads the data from file fileName, checking whether the data in each column of the file is or not a string, and whether the data in each row is or not valid.
