Detailed Description

template<typename Type, class RawAllocator>
class foonathan::memory::allocator_deallocator< Type[], RawAllocator >

Specialization of allocator_deallocator for array types.

Otherwise the same behavior.

Typedefs
using	allocator_type = typename allocator_reference< RawAllocator >::allocator_type

using	value_type = Type

Member Functions
	allocator_deallocator () noexcept

	allocator_deallocator (allocator_reference< RawAllocator > alloc, std::size_t size) noexcept

void	operator() (value_type *pointer) noexcept

auto	get_allocator () const noexcept -> decltype(std::declval< allocator_reference< allocator_type > >().get_allocator())

std::size_t	array_size () const noexcept

Constructors

allocator_deallocator ( )

noexcept

Effects:: Creates it without any associated allocator. The deallocator must not be used if that is the case.

Notes:: This functions is useful if you have want to create an empty smart pointer without giving it an allocator.

allocator_deallocator	(	allocator_reference< RawAllocator >	alloc,
		std::size_t	size
	)

noexcept

Effects:: Creates it by passing it an allocator_reference and the size of the array that will be deallocated. It will store the reference to the allocator and uses the referenced allocator object for the deallocation.

void operator() ( value_type * pointer )

noexcept

Effects:: Deallocates the memory given to it. Calls deallocate_array(pointer, size, sizeof(value_type), alignof(value_type)) on the referenced allocator object with the size given in the constructor.

Requires:: The deallocator must not have been created by the default constructor.

auto get_allocator ( ) const -> decltype(std::declval<allocator_reference<allocator_type>>().get_allocator())

noexcept

Returns:: The reference to the allocator. It has the same type as the call to allocator_reference::get_allocator().

Requires:: The deallocator must not have been created by the default constructor.

std::size_t array_size ( ) const

noexcept

Returns:: The size of the array that will be deallocated. This is the same value as passed in the constructor, or 0 if it was created by the default constructor.
