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 sub_match< _BiIter > & __s) const
       [inline]
       Compares this and another matched sequence.

       Parameters:
           __s Another matched sequence to compare to this one.

       Return values:
           <0 this matched sequence will collate before __s.
           =0 this matched sequence is equivalent to __s.
           <0 this matched sequence will collate after __s.

   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:
           <0 this matched sequence will collate before __s.
           =0 this matched sequence is equivalent to __s.
           <0 this matched sequence will collate after __s.

       Definition at line 815 of file regex.h.

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

       Parameters:
           __s A C-style string to compare to this sub_match.

       Return values:
           <0 this matched sequence will collate before __s.
           =0 this matched sequence is equivalent to __s.
           <0 this matched sequence will collate after __s.

       Definition at line 828 of file regex.h.

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

       Definition at line 759 of file regex.h.

   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.

       Definition at line 772 of file regex.h.

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

       Returns:
           the matching sequence as a string.
