Detailed Description

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.

Member Typedef Documentation

◆ first_type

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

The type of the first member.

Definition at line 203 of file stl_pair.h.

◆ second_type

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

The type of the second member.

Definition at line 204 of file stl_pair.h.

Member Function Documentation

◆ swap()

constexpr void std::pair< _Iterator1 , _Iterator2 >::swap ( pair< _Iterator1, _Iterator2 > &  __p)
inlineconstexprnoexceptinherited

Swap the first members and then the second members.

Friends And Related Function Documentation

◆ make_pair()

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
__xThe first object.
__yThe 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 739 of file stl_pair.h.

◆ operator!=()

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

Uses operator== to find the result.

Definition at line 668 of file stl_pair.h.

◆ operator<()

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 660 of file stl_pair.h.

◆ operator<=()

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

Uses operator< to find the result.

Definition at line 679 of file stl_pair.h.

◆ operator==()

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 638 of file stl_pair.h.

◆ operator>()

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

Uses operator< to find the result.

Definition at line 674 of file stl_pair.h.

◆ operator>=()

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

Uses operator< to find the result.

Definition at line 686 of file stl_pair.h.

◆ swap()

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
