class std::sub_match< _BiIter >"A sequence of characters matched by a particular marked sub-expression\&.
.PP
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 the same character type as the pattern matched by the regular expression\&.
.PP
A \fCsub_match<Iter>\fP has a public base class of type \fCpair<Iter, Iter>\fP, so inherits pair's data members named \fCfirst\fP and \fCsecond\fP\&. The iterators that make up the pair are the usual half-open interval referencing the actual original pattern matched\&.
