fractionalFileReadASCII()

LookupTable1D< Real, 1 > DataParser::fractionalFileReadASCII	(	const std::string	a_fileName,
		const std::string	a_startRead,
		const std::string	a_stopRead,
		const int	a_xColumn = 0,
		const int	a_yColumn = 1,
		const std::vector< char >	a_ignoreChars = {'#', '/'}
	)

Simple ASCII file parser which reads a file and puts the data into two columns (a lookup table)

This version can read a partial file. It will ignore all lines until the a_startRead string is encountered. After that, it will read files as usual, skipping lines that begin with comments. Empty lines are NOT skipped, since an empty line typically identifies the end of a field from e.g. BOLSIG outputs. Instead to stop reading when an empty line is encountered, one can use a_stopRead="".

Parameters

[in]	a_fileName	Input file name. Must be an ASCII file organized into rows and columns.
[in]	a_startRead	Identifier where we start parsing lines into the table
[in]	a_stopRead	Identifier where we stop parsing lines into the table
[in]	a_xColumn	Which column to use as the x-column.
[in]	a_yColumn	Which column to use as the y-column.
[in]	a_ignoreChars	Characters indicating comments in the file. Lines starting with these characters are ignored.

readPointParticlesASCII()

List< PointParticle > DataParser::readPointParticlesASCII	(	const std::string	a_fileName,
		const unsigned int	a_xColumn = 0,
		const unsigned int	a_yColumn = 1,
		const unsigned int	a_zColumn = 2,
		const unsigned int	a_wColumn = 3,
		const std::vector< char >	a_ignoreChars = {'#', '/'}
	)

Simple file parser which will read particles (position/weight) from an ASCII file.

Particles should be arranged as rows, e.g. in the form x y z w 0.0 0.0 0.0 1

Parameters

[in]	a_fileName	Input file name. Must be an ASCII file organized into rows and columns.
[in]	a_xColumn	Column containing the x-coordinate
[in]	a_yColumn	Column containing the y-coordinate
[in]	a_zColumn	Column containing the z-coordinate
[in]	a_wColumn	Column containing the particle weight
[in]	a_ignoreChars	Characters indicating comments in the file. Lines starting with these characters are ignored.

simpleFileReadASCII()

LookupTable1D< Real, 1 > DataParser::simpleFileReadASCII	(	const std::string	a_fileName,
		const int	a_xColumn = 0,
		const int	a_yColumn = 1,
		const std::vector< char >	a_ignoreChars = {'#', '/'}
	)

Simple file parser which reads a file and puts the data into two columns (a lookup table).

This will read ASCII row/column data into a LookupTable1D (which is a simple x-y data structure). The user can specify which columns to use as the x and y coordinates in the LookupTable1D. If the user ask for a column that does not exist in the input file, the data will not be read into the LookupTable1D.

Parameters

[in]	a_fileName	Input file name. Must be an ASCII file organized into rows and columns.
[in]	a_xColumn	Which column to use as the x-column.
[in]	a_yColumn	Which column to use as the y-column.
[in]	a_ignoreChars	Characters indicating comments in the file. Lines starting with these characters are ignored.

Note

xColumn = 0 is the FIRST column, xColumn=1 is the SECOND column and so on.
