Member Function Documentation
template<typename _Alloc> static pointer std::allocator_traits< _Alloc >::allocate (_Alloc &__a, size_type__n) [inline], [static],
[inherited]
Allocate memory. Parameters:
__a An allocator.
__n The number of objects to allocate space for.
Calls a.allocate(n)
Definition at line 348 of file bits/alloc_traits.h.
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:
__a An allocator.
__n The number of objects to allocate space for.
__hint Aid to locality.
Returns:
Memory of suitable size and alignment for n objects of type value_type
Returns a.allocate(n, hint) if that expression is well-formed, otherwise returns a.allocate(n)
Definition at line 363 of file bits/alloc_traits.h.
template<typename _Alloc> template<typename _Tp , typename... _Args> static void std::allocator_traits< _Alloc >::construct (_Alloc &__a, _Tp
*__p, _Args &&...__args) [inline], [static], [inherited]
Construct an object of type _Tp. Parameters:
__a An allocator.
__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...
Definition at line 389 of file bits/alloc_traits.h.
template<typename _Alloc> static void std::allocator_traits< _Alloc >::deallocate (_Alloc &__a, pointer__p, size_type__n) [inline], [static],
[inherited]
Deallocate memory. Parameters:
__a An allocator.
__p Pointer to the memory to deallocate.
__n The number of objects space was allocated for.
Calls a.deallocate(p, n)
Definition at line 374 of file bits/alloc_traits.h.
template<typename _Alloc> template<class _Tp > static void std::allocator_traits< _Alloc >::destroy (_Alloc &__a, _Tp *__p) [inline],
[static], [inherited]
Destroy an object of type _Tp. Parameters:
__a An allocator.
__p Pointer to the object to destroy
Calls __a.destroy(__p) if that expression is well-formed, otherwise calls __p->~_Tp()
Definition at line 401 of file bits/alloc_traits.h.
template<typename _Alloc> static size_type std::allocator_traits< _Alloc >::max_size (const _Alloc &__a) [inline], [static], [inherited]
The maximum supported allocation size. Parameters:
__a An allocator.
Returns:
__a.max_size() or numeric_limits<size_type>::max()
Returns __a.max_size() if that expression is well-formed, otherwise returns numeric_limits<size_type>::max()
Definition at line 412 of file bits/alloc_traits.h.
template<typename _Alloc> static _Alloc std::allocator_traits< _Alloc >::select_on_container_copy_construction (const _Alloc &__rhs) [inline],
[static], [inherited]
Obtain an allocator to use when copying a container. Parameters:
__rhs An allocator.
Returns:
__rhs.select_on_container_copy_construction() or __rhs
Returns __rhs.select_on_container_copy_construction() if that expression is well-formed, otherwise returns __rhs
