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 895 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 908 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 839 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 852 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.
