Member Typedef Documentation

typedef _Iterator1 std::pair< _Iterator1 , _Iterator2 >::first_type [inherited]

The type of the first member.

Definition at line 214 of file stl_pair.h.

typedef _Iterator2 std::pair< _Iterator1 , _Iterator2 >::second_type [inherited]

The type of the second member.

Definition at line 215 of file stl_pair.h.

Member Function Documentation

constexpr void std::pair< _Iterator1 , _Iterator2 >::swap (pair< _Iterator1, _Iterator2 > & __p) [inline], [constexpr], [noexcept], [inherited]

Swap the first members and then the second members.

Definition at line 439 of file stl_pair.h.

Friends And Related Function Documentation

constexpr pair< typename __decay_and_strip< _Iterator1 >::__type, typename __decay_and_strip< _Iterator2 >::__type > make_pair (_Iterator1 && __x, _Iterator2 && __y) [related]

A convenience wrapper for creating a pair from two objects.

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.

constexpr bool operator!= (const pair< _Iterator1 , _Iterator2 > & __x, const pair< _Iterator1 , _Iterator2 > & __y) [related]

Uses operator== to find the result.

Definition at line 496 of file stl_pair.h.

constexpr bool operator< (const pair< _Iterator1 , _Iterator2 > & __x, const pair< _Iterator1 , _Iterator2 > & __y) [related]

Defines a lexicographical order for pairs.

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.

constexpr bool operator<= (const pair< _Iterator1 , _Iterator2 > & __x, const pair< _Iterator1 , _Iterator2 > & __y) [related]

Uses operator< to find the result.

Definition at line 507 of file stl_pair.h.

constexpr bool operator== (const pair< _Iterator1 , _Iterator2 > & __x, const pair< _Iterator1 , _Iterator2 > & __y) [related]

Two pairs of the same type are equal iff their members are equal.

Definition at line 466 of file stl_pair.h.

constexpr bool operator> (const pair< _Iterator1 , _Iterator2 > & __x, const pair< _Iterator1 , _Iterator2 > & __y) [related]

Uses operator< to find the result.

Definition at line 502 of file stl_pair.h.

constexpr bool operator>= (const pair< _Iterator1 , _Iterator2 > & __x, const pair< _Iterator1 , _Iterator2 > & __y) [related]

Uses operator< to find the result.

Definition at line 514 of file stl_pair.h.

constexpr enable_if< __and_< __is_swappable< _Iterator1 >, __is_swappable< _Iterator2 > >::value >::type swap (pair< _Iterator1 , _Iterator2 > & __x, pair< _Iterator1 , _Iterator2 > & __y) [related]

Swap overload for pairs. Calls std::pair::swap().

Note

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