	Returns the index (counting from 0) of the line within the current column this part belongs to.

int	length ()
	Returns the length of the part pointed to by data() in raw chars (not UTF-8 characters).

◆ next()

bool option::PrintUsageImplementation::LinePartIterator::next ( )

inline

Moves iteration to the next part (if any). Has to be called once after each call to nextRow() to move to the 1st part of the row.

Return values

false if moving to next part failed because no further part exists.

See LinePartIterator for details about the iteration.

inline

Moves iteration to the next row (if any). Has to be called once after each call to nextTable() to move to the 1st row of the table.

Return values

false if moving to next row failed because no further row exists.
