Member Function Documentation

template<typename _Alloc>

static _GLIBCXX_NODISCARD 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 305 of file bits/alloc_traits.h.

template<typename _Alloc>

static _GLIBCXX_NODISCARD 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 320 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
	)		[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...

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 332 of file bits/alloc_traits.h.

template<typename _Alloc>

template<typename _Tp >

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