CsvParser Class Reference

#include "lib/stat/csv.hpp"

Description

Parser to split one line of CSV data into fields.

Remarks

iterator-like throw-away object

• the bool evaluation indicates more fields to extract
• dereference to get the field as string
• increment to move to the next field

Exceptions

error::Invalid

on CSV format violation
