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.

_PCCFP

using std::pair< _BiIter , _BiIter >::_PCCFP = _PCC<!is_same<_BiIter , _U1>::value || !is_same<_BiIter , _U2>::value, _BiIter , _BiIter >

inherited

There is also a templated copy ctor for the pair class itself.

inherited

Two objects may be passed to a pair constructor to be copied.

Member Function Documentation

compare() [1/3]

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.

Definition at line 918 of file regex.h.

compare() [2/3]

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 932 of file regex.h.

compare() [3/3]

template<typename _BiIter>

int std::sub_match< _BiIter >::compare ( const 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 936 of file regex.h.

length()

template<typename _BiIter>

difference_type std::sub_match< _BiIter >::length ( ) const

inlinenoexcept

Gets the length of the matching sequence.

Definition at line 879 of file regex.h.

operator string_type()

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 892 of file regex.h.

str()

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.

Definition at line 901 of file regex.h.
