Detailed Description

   template<typename _BiIter>
       class std::sub_match< _BiIter >" A sequence of characters matched by a particular marked
       sub-expression.

       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.

Member Function Documentation

   template<typename _BiIter > int std::sub_match< _BiIter >::compare (const string_type & __s)
       const [inline]
       Compares this `sub_match` to a string.

       Parameters
           __s A string to compare to this `sub_match`.

       Return values
           negative This matched sequence will collate before `__s`.
           zero This matched sequence is equivalent to `__s`.
           positive This matched sequence will collate after `__s`.

       Definition at line 932 of file regex.h.

   template<typename _BiIter > int std::sub_match< _BiIter >::compare (const sub_match< _BiIter >
       & __s) const [inline]
       Compares this and another matched sequence.

       Parameters
           __s Another matched sequence to compare to this one.

       Return values
           negative This matched sequence will collate before `__s`.
           zero This matched sequence is equivalent to `__s`.
           positive This matched sequence will collate after `__s`.

   template<typename _BiIter > int std::sub_match< _BiIter >::compare (const value_type * __s)
       const [inline]
       Compares this `sub_match` to a string.

       Parameters
           __s A string to compare to this `sub_match`.

       Return values
           negative This matched sequence will collate before `__s`.
           zero This matched sequence is equivalent to `__s`.
           positive This matched sequence will collate after `__s`.

   template<typename _BiIter > difference_type std::sub_match< _BiIter >::length () const
       [inline],  [noexcept]
       Gets the length of the matching sequence.

   template<typename _BiIter > std::sub_match< _BiIter >::operator string_type () const [inline]
       Gets the matching sequence as a string.

       Returns
           the matching sequence as a string.

       This is the implicit conversion operator. It is identical to the str() member function
       except that it will want to pop up in unexpected places and cause a great deal of
       confusion and cursing from the unwary.

   template<typename _BiIter > string_type std::sub_match< _BiIter >::str () const [inline]
