Methods Documentation

get_data_lines(lines)

READ: Set data_lines attribute to lines slice comprising table data values.

get_str_vals()

Return a generator that returns a list of column values (as strings) for each data line.

masks(cols)

READ: Set fill value for each column and then apply that fill value.

In the first step it is evaluated with value from fill_values applies to which column using fill_include_names and fill_exclude_names. In the second step all replacements are done for the appropriate columns.

process_lines(lines)

READ: Strip out comment lines and blank lines from list of lines.

Parameters:

lineslist

All lines in table

Returns:

lineslist

List of lines

str_vals()

WRITE: convert all values in table to a list of lists of strings.

This sets the fill values and possibly column formats from the input formats={} keyword, then ends up calling table.pprint._pformat_col_iter() by a circuitous path. That function does the real work of formatting. Finally replace anything matching the fill_values.

Returns:

valueslist of list of str

write(lines)

Write self.cols in place to lines.

Parameters:

lineslist

List for collecting output of writing self.cols.
