.SS "template<typename _BiIter>
.br
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 a similar base character type as the pattern matched by the regular expression\&.
.PP
The iterators that make up the pair are the usual half-open interval referencing the actual original pattern matched\&.

There is also a templated copy ctor for the \fCpair\fP class itself\&.
