Member Function Documentation
| static pointer std::allocator_traits< _Alloc >::allocate | ( | _Alloc & | __a, |
| size_type | __n | ||
| ) | [inline, static] |
Allocate memory.
- Parameters:
-
__a An allocator. __n The number of objects to allocate space for.
Calls a.allocate(n)
Definition at line 345 of file bits/alloc_traits.h.
| static pointer std::allocator_traits< _Alloc >::allocate | ( | _Alloc & | __a, |
| size_type | __n, | ||
| const_void_pointer | __hint | ||
| ) | [inline, static] |
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 360 of file bits/alloc_traits.h.
| static void std::allocator_traits< _Alloc >::construct | ( | _Alloc & | __a, |
| _Tp * | __p, | ||
| _Args &&... | __args | ||
| ) | [inline, static] |
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...
