template<typename _Iterator1, typename _Iterator2, typename _IteratorCategory>¶

class __gnu_parallel::_IteratorPair< _Iterator1, _Iterator2, _IteratorCategory >" A pair of iterators. The usual iterator operations are applied to both child iterators.

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.

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

Swap the first members and then the second members.

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

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

_Iterator1 std::pair< _Iterator1 , _Iterator2 >::first [inherited]¶

The first member.

_Iterator2 std::pair< _Iterator1 , _Iterator2 >::second [inherited]¶

The second member.
