Member Function Documentation

◆ allocate()

static void * std::allocator_traits< allocator< void > >::allocate ( allocator_type &  ,
size_type  ,
const void *  = nullptr 
)
staticdelete

allocate is ill-formed for allocator<void>

◆ construct()

template<typename _Up , typename... _Args>
static constexpr void std::allocator_traits< allocator< void > >::construct ( allocator_type &  ,
_Up *  __p,
_Args &&...  __args 
)
inlinestaticconstexprnoexcept

Construct an object of type _Up

Parameters
__aAn allocator.
__pPointer to memory of suitable size and alignment for an object of type _Up.
__argsConstructor arguments.

Calls __a.construct(__p, std::forward<_Args>(__args)...) in C++11, C++14 and C++17. Changed in C++20 to call std::construct_at(__p, std::forward<_Args>(__args)...) instead.

Definition at line 633 of file bits/alloc_traits.h.

References std::_Construct().

◆ deallocate()

static void std::allocator_traits< allocator< void > >::deallocate ( allocator_type &  ,
void *  ,
size_type   
)
staticdelete

deallocate is ill-formed for allocator<void>

◆ destroy()

template<typename _Up >
static constexpr void std::allocator_traits< allocator< void > >::destroy ( allocator_type &  ,
_Up *  __p 
)
inlinestaticconstexprnoexcept

Destroy an object of type _Up

Parameters
__aAn allocator.
__pPointer to the object to destroy

Invokes the destructor for *__p.

Definition at line 646 of file bits/alloc_traits.h.

References std::_Destroy().

◆ max_size()

static size_type std::allocator_traits< allocator< void > >::max_size ( const allocator_type &  )
staticdelete

max_size is ill-formed for allocator<void>

◆ select_on_container_copy_construction()

static constexpr allocator_type std::allocator_traits< allocator< void > >::select_on_container_copy_construction ( const allocator_type &  __rhs)
inlinestaticconstexpr

Obtain an allocator to use when copying a container.

Parameters
__rhsAn allocator.
Returns
__rhs
