Function Documentation

◆ pair() [1/2]

template<typename _T1, typename _T2>
pair ( _T1 ,
_T2  )->pair< _T1, _T2 >
related

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

◆ pair() [2/2]

template<class _T1, class _T2>
template<typename... _Args1, typename... _Args2>
std::pair< _T1, _T2 >::pair ( piecewise_construct_t ,
tuple< _Args1... > __first,
tuple< _Args2... > __second )
inlineconstexpr

"piecewise construction" using a tuple of arguments for each member.

Parameters
__firstArguments for the first member of the pair.
__secondArguments for the second member of the pair.

The elements of each tuple will be used as the constructor arguments for the data members of the pair.

Definition at line 2251 of file tuple.

References pair().

◆ __addressof()

template<typename _Tp>
_Tp * std::__addressof ( _Tp & __r)
inlineconstexprnoexcept

Same as C++11 std::addressof.

constexpr

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.

template<typename _Tp>
__conditional_t< __move_if_noexcept_cond< _Tp >::value, const _Tp &, _Tp && > std::move_if_noexcept ( _Tp & __x)
nodiscardconstexprnoexcept

Conditionally convert a value to an rvalue.

Parameters
__xA thing of arbitrary type.
Returns
The parameter, possibly cast to an rvalue-reference.

Same as std::move unless the type's move constructor could throw and the type is copyable, in which case an lvalue-reference is returned instead.

◆ ignore

_Swallow_assign std::ignore
inlineconstexpr

Used with std::tie to ignore an element of a tuple

When using std::tie to assign the elements of a tuple to variables, unwanted elements can be ignored by using std::ignore. For example:

int x, y;
std::tie(x, std::ignore, y) = std::make_tuple(1, 2, 3);
std::make_tuple
constexpr tuple< typename __decay_and_strip< _Elements >::__type... > make_tuple(_Elements &&... __args)
Create a tuple containing copies of the arguments.
Definition tuple:2000
std::ignore
constexpr _Swallow_assign ignore
Definition tuple:2232
std::tie
constexpr tuple< _Elements &... > tie(_Elements &... __args) noexcept
Return a tuple of lvalue references bound to the arguments.
Definition tuple:2168

This assignment will perform x=1; std::ignore=2; y=3; which results in the second element being ignored.
