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 the same character type as the pattern matched by the regular expression.

A sub_match<Iter> has a public base class of type pair<Iter, Iter>, so inherits pair's data members named first and second. The iterators that make up the pair are the usual half-open interval referencing the actual original pattern matched.

Since: C++11

Member Function Documentation

◆ compare() [1/3]

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

negative	This matched sequence will collate before `__s`.
zero	This matched sequence is equivalent to `__s`.
positive	This matched sequence will collate after `__s`.

Definition at line 994 of file regex.h.

◆ compare() [2/3]

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

negative	This matched sequence will collate before `__s`.
zero	This matched sequence is equivalent to `__s`.
positive	This matched sequence will collate after `__s`.

◆ 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

negative	This matched sequence will collate before `__s`.
zero	This matched sequence is equivalent to `__s`.
positive	This matched sequence will collate after `__s`.

◆ length()

template<typename _BiIter >

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

inlinenoexcept

Gets the length of the matching sequence.

Definition at line 941 of file regex.h.

References std::distance().

◆ 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 954 of file regex.h.

References std::sub_match< _BiIter >::str().

◆ 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.

◆ swap()

template<typename _BiIter >

void std::sub_match< _BiIter >::swap ( sub_match< _BiIter > & __s )

inlinenoexcept

Swap the values of two sub_match objects.
