Functions
void	csv::CSVReader::set_col_names (const std::vector< std::string > &)
	Sets this reader's column names and associated data.

CSV Settings
CSVFormat	csv::CSVReader::_format

Parser State
internals::ColNamesPtr	csv::CSVReader::col_names = std::make_shared<internals::ColNames>()
	Pointer to a object containing column information.
std::unique_ptr< internals::parser::CSVParserDriverBase >	csv::CSVReader::parser = nullptr
	Helper class which actually does the parsing.
std::unique_ptr< RowCollection >	csv::CSVReader::records {new RowCollection(100)}
	Queue of parsed CSV rows.
std::unique_ptr< std::istream >	csv::CSVReader::owned_stream = nullptr
	Optional owned stream used by two paths: 1) Emscripten filename-constructor fallback to stream parsing 2) Opt-in ownership constructor taking std::unique_ptr<std::istream>
size_t	csv::CSVReader::n_cols = 0
	The number of columns in this CSV.
size_t	csv::CSVReader::_n_rows = 0
	How many rows (minus header) have been read so far.

Worker Reading Functions
Functions that actively drive parser execution and produce rows.
bool	csv::CSVReader::read_csv (size_t bytes=internals::CSV_CHUNK_SIZE_DEFAULT)
	Read a chunk of CSV data.

Detailed Description

Internals of CSVReader.

Only maintainers and those looking to extend the parser should read this.

Function Documentation

read_csv()

bool csv::CSVReader::read_csv ( size_t  bytes = internals::CSV_CHUNK_SIZE_DEFAULT )

protected

Read a chunk of CSV data.

Note

This method may run on a worker thread or synchronously on the caller thread when CSVFormat::threading(false) is active. Only one read_csv() invocation should be active at a time.
