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.

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 1170 of file tr1_impl/regex.
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.
Definition at line 1157 of file tr1_impl/regex.
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> 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.
Definition at line 1114 of file tr1_impl/regex.
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.
