Member Function Documentation

template<typename _Alloc>

static pointer std::allocator_traits< _Alloc >::allocate	(	_Alloc &	__a,
		size_type	__n
	)

inlinestaticinherited

Allocate memory.

Parameters

__a	An allocator.
__n	The number of objects to allocate space for.

Calls a.allocate(n)

Definition at line 350 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
	)

inlinestaticinherited

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 365 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)...))

inlinestaticinherited

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 391 of file bits/alloc_traits.h.

template<typename _Alloc>

static void std::allocator_traits< _Alloc >::deallocate	(	_Alloc &	__a,
		pointer	__p,
		size_type	__n
	)

inlinestaticinherited

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 376 of file bits/alloc_traits.h.

template<typename _Alloc>

template<class _Tp >

static void std::allocator_traits< _Alloc >::destroy	(	_Alloc &	__a,
		_Tp *	__p
	)

inlinestaticinherited

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 404 of file bits/alloc_traits.h.

template<typename _Alloc>

static size_type std::allocator_traits< _Alloc >::max_size ( const _Alloc & __a )

inlinestaticnoexceptinherited

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 415 of file bits/alloc_traits.h.

Referenced by std::forward_list< _Tp, _Alloc >::max_size().

static _Alloc std::allocator_traits< _Alloc >::select_on_container_copy_construction ( const _Alloc & __rhs )

inlinestaticinherited

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
