Member Typedef Documentation¶
template<typename _Alloc> typedef __const_void_pointer std::allocator_traits< _Alloc >::const_void_pointer [inherited]¶

Definition at line 172 of file bits/alloc_traits.h.
template<typename _Alloc> typedef __propagate_on_container_move_assignment std::allocator_traits< _Alloc >::propagate_on_container_move_assignment [inherited]¶

Member Function Documentation¶
template<typename _Alloc> static pointer std::allocator_traits< _Alloc >::allocate (_Alloc & __a, size_type __n) [inline], [static], [inherited]¶
Allocate memory.
Parameters:
__n The number of objects to allocate space for.
Calls a.allocate(n)

Referenced by std::__allocate_guarded().
template<typename _Alloc> static pointer std::allocator_traits< _Alloc >::allocate (_Alloc & __a, size_type __n, const_void_pointer __hint) [inline], [static], [inherited]¶
Allocate memory.
Parameters:
__n The number of objects to allocate space for.
__hint Aid to locality.
Returns:
Returns a.allocate(n, hint) if that expression is well-formed, otherwise returns a.allocate(n)
Definition at line 374 of file bits/alloc_traits.h.
template<typename _Alloc> template<typename _Tp , typename... _Args> static auto std::allocator_traits< _Alloc >::construct (_Alloc & __a, _Tp * __p, _Args &&... __args) -> decltype(_S_construct(__a, __p, std::forward<_Args>(__args)...))¶
[inline], [static], [inherited]"
Construct an object of type _Tp.
Parameters:
__p Pointer to memory of suitable size and alignment for Tp
__args Constructor arguments.
Calls __a.construct(__p, std::forward<Args>(__args)...) if that expression is well-formed, otherwise uses placement-new to construct an object of type _Tp at location __p from the arguments __args...

template<typename _Alloc> static void std::allocator_traits< _Alloc >::deallocate (_Alloc & __a, pointer __p, size_type __n) [inline], [static], [inherited]¶
Deallocate memory.
Parameters:
__p Pointer to the memory to deallocate.
__n The number of objects space was allocated for.
Calls a.deallocate(p, n)

Destroy an object of type _Tp.
Parameters:
__p Pointer to the object to destroy
Calls __a.destroy(__p) if that expression is well-formed, otherwise calls __p->~_Tp()
Definition at line 413 of file bits/alloc_traits.h.
