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:
__sAnother matched sequence to compare to this one.
Return values:
<0this matched sequence will collate before __s.
=0this matched sequence is equivalent to __s.
<0this 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:
__sA string to compare to this sub_match.
Return values:
<0this matched sequence will collate before __s.
=0this matched sequence is equivalent to __s.
<0this matched sequence will collate after __s.

Definition at line 834 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:
__sA C-style string to compare to this sub_match.
Return values:
<0this matched sequence will collate before __s.
=0this matched sequence is equivalent to __s.
<0this matched sequence will collate after __s.

Definition at line 847 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 778 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 791 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.
