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 831 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.

template<typename _BiIter> difference_type std::sub_match< _BiIter >::length () const [inline]
Gets the length of the matching sequence.
Definition at line 775 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 788 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.
