Member Function Documentation
| int dballe::CSVReader::as_int | ( | unsigned | col | ) | const |
Return the given column, as an integer.
A missing value raises an exception.
| int dballe::CSVReader::as_int_withmissing | ( | unsigned | col | ) | const |
Return the given column, as an integer.
A missing value is returned as MISSING_INT.
| wreport::Varcode dballe::CSVReader::as_varcode | ( | unsigned | col | ) | const |
Return the given column, as a Varcode.
A missing value raises an exception.
| void dballe::CSVReader::close | ( | ) |
Sets in to 0.
If close_on_exit is true, close the currently opened file.
| bool dballe::CSVReader::move_to_data | ( | unsigned | number_col = 0 | ) |
Find the first line where the given column exists and starts with a number.
This can be used to skip titles and empty lines, moving to the start of the real data. Real data is identified by using a column that starts with text in the headers and number in the data.
- Returns
- true if a data line has been found, false if we reached EOF
