An object of this class is essentially a pair of iterators marking a matched subexpression within a regular expression pattern match. Such objects can be converted to and compared with std::basic_string objects of a similar base character type as the pattern matched by the regular expression. The iterators that make up the pair are the usual half-open interval referencing the actual original pattern matched. Definition at line 741 of file regex.h.
