| std::pair<std::string,_VDBL_colid> _VDBL_standardtable::_next_col | ( | const std::pair< std::string, _VDBL_colid > & | _ci | ) | const [inline, virtual, inherited] |
This virtual function has to be overloaded by the derived table classes, and it performs the step to the next column for a _col_iterator. This virtual function has to be overloaded by the derived table classes, and it performs the step to the previous column for a _col_iterator. return iterator to first column return iterator beyond last column This is the fundamental class for iterators over all rows, defining basic in(de)crementation for overloading, and basic comparison.
