Constructor & Destructor Documentation

L1GtPatternWriter::L1GtPatternWriter	(	std::ostream &	destination,
		const std::string &	header,
		const std::string &	footer,
		const std::vector< std::string >	columns,
		const std::vector< boost::uint32_t > &	lengths,
		const std::vector< boost::uint32_t > &	defaultValues,
		const std::vector< int > &	bx,
		bool	debug = `false`
	)

Construct a new pattern writer.

Parameters:

destination	output stream to write to
header	string to be written before pattern lines
footer	string to be written after pattern lines
columns	vector of column names for each pattern line
length	vector of column lengths (in bits!) for each pattern line
defaults	vector of default values (written if the pattern data does not contain entries for the column). Indexed like columns.
bx	vector of bunch crossing numbers to print (empty for 'all')
debug	set to true to enable extensive debug logging
