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

◆ 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 937 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`.

Definition at line 941 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 884 of file regex.h.

References std::distance(), std::pair< _BiIter, _BiIter >::first, and std::pair< _BiIter, _BiIter >::second.

◆ 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 897 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.

Definition at line 906 of file regex.h.

References std::pair< _BiIter, _BiIter >::first, and std::pair< _BiIter, _BiIter >::second.

◆ swap()

constexpr void std::pair< _BiIter , _BiIter >::swap ( pair< _BiIter, _BiIter > & __p )

inlineconstexprnoexceptinherited

Swap the first members and then the second members.

Definition at line 439 of file stl_pair.h.

◆ make_pair()

constexpr pair< typename __decay_and_strip< _BiIter >::__type, typename __decay_and_strip< _BiIter >::__type > make_pair	(	_BiIter &&	__x,
		_BiIter &&	__y
	)

Parameters

__x	The first object.
__y	The second object.

Returns: A newly-constructed pair<> object of the appropriate type.

The C++98 standard says the objects are passed by reference-to-const, but C++03 says they are passed by value (this was LWG issue #181).

Since C++11 they have been passed by forwarding reference and then forwarded to the new members of the pair. To create a pair with a member of reference type, pass a reference_wrapper to this function.

Definition at line 567 of file stl_pair.h.

◆ operator!=()

constexpr bool operator!=	(	const pair< _BiIter , _BiIter > &	__x,
		const pair< _BiIter , _BiIter > &	__y
	)

Definition at line 496 of file stl_pair.h.

◆ operator<()

constexpr bool operator<	(	const pair< _BiIter , _BiIter > &	__x,
		const pair< _BiIter , _BiIter > &	__y
	)

For two pairs of the same type, P is ordered before Q if P.first is less than Q.first, or if P.first and Q.first are equivalent (neither is less than the other) and P.second is less than Q.second.

Definition at line 488 of file stl_pair.h.

◆ operator<=()

constexpr bool operator<=	(	const pair< _BiIter , _BiIter > &	__x,
		const pair< _BiIter , _BiIter > &	__y
	)

Definition at line 507 of file stl_pair.h.

◆ operator==()

constexpr bool operator==	(	const pair< _BiIter , _BiIter > &	__x,
		const pair< _BiIter , _BiIter > &	__y
	)

Definition at line 466 of file stl_pair.h.

◆ operator>()

constexpr bool operator>	(	const pair< _BiIter , _BiIter > &	__x,
		const pair< _BiIter , _BiIter > &	__y
	)

Definition at line 502 of file stl_pair.h.

◆ operator>=()

constexpr bool operator>=	(	const pair< _BiIter , _BiIter > &	__x,
		const pair< _BiIter , _BiIter > &	__y
	)

Definition at line 514 of file stl_pair.h.

◆ swap()

constexpr enable_if< __and_< __is_swappable< _BiIter >, __is_swappable< _BiIter > >::value >::type swap	(	pair< _BiIter , _BiIter > &	__x,
		pair< _BiIter , _BiIter > &	__y
	)

Note: This std::swap overload is not declared in C++03 mode, which has performance implications, e.g. see https://gcc.gnu.org/PR38466
