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 basic_string<
       value_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.

   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.

   template<typename _BiIter> difference_type std::sub_match< _BiIter >::length () const [inline]
       Gets the length of the matching sequence.
       Definition at line 1101 of file tr1_impl/regex.

   template<typename _BiIter> std::sub_match< _BiIter >::operator basic_string< value_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> basic_string<value_type> std::sub_match< _BiIter >::str () const
       [inline]
       Gets the matching sequence as a string. Returns:
           the matching sequence as a string.
