Member Typedef Documentation¶
typedef _Iterator1 std::pair< _Iterator1 , _Iterator2 >::first_type [inherited]¶
The type of the first member.
typedef _Iterator2 std::pair< _Iterator1 , _Iterator2 >::second_type [inherited]¶
The type of the second member.
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.
Friends And Related Symbol 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
__y The second object.
Returns
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.
constexpr bool operator!= (const pair< _Iterator1 , _Iterator2 > & __x, const pair< _Iterator1 , _Iterator2 > & __y) [related]¶
Uses operator== to find the result.
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.
constexpr bool operator<= (const pair< _Iterator1 , _Iterator2 > & __x, const pair< _Iterator1 , _Iterator2 > & __y) [related]¶
Uses operator< to find the result.
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.
constexpr bool operator> (const pair< _Iterator1 , _Iterator2 > & __x, const pair< _Iterator1 , _Iterator2 > & __y) [related]¶
Uses operator< to find the result.
constexpr bool operator>= (const pair< _Iterator1 , _Iterator2 > & __x, const pair< _Iterator1 , _Iterator2 > & __y) [related]¶
Uses operator< to find the result.
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
