allocator_deleter< Type[], RawAllocator > Class Template Reference

Detailed Description

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

Specialization of allocator_deleter for array types.

Otherwise the same behavior.

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

Member Functions
	allocator_deleter () noexcept
	allocator_deleter (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_deleter() [1/2]

allocator_deleter ( )

noexcept

Effects:

Creates it without any associated allocator. The deleter 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_deleter() [2/2]

allocator_deleter ( 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.

Member Functions

operator()()

void operator() ( value_type *  pointer )

noexcept

Effects:

Calls the destructors and 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 for the deallocation.

Requires:

The deleter must not have been created by the default constructor.

get_allocator()

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 deleter must not be created by the default constructor.

array_size()

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.
