allocator_deleter< Type, RawAllocator > Class Template Reference

Detailed Description

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

Similar to allocator_deallocator but calls the destructors of the object.

Otherwise behaves the same.

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

Member Functions
	allocator_deleter () noexcept=default
	allocator_deleter (allocator_reference< RawAllocator > alloc) noexcept
void	operator() (value_type *pointer) noexcept
auto	get_allocator () const noexcept -> decltype(std::declval< allocator_reference< allocator_type > >().get_allocator())

Constructors

allocator_deleter() [1/2]

allocator_deleter ( )

defaultnoexcept

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 )

noexcept

Effects:

Creates it by passing it an allocator_reference. It will store the reference to it and uses the referenced allocator object for the deallocation.

Member Functions

operator()()

void operator() ( value_type *  pointer )

noexcept

Effects:

Calls the destructor and deallocates the memory given to it. Calls deallocate_node(pointer, sizeof(value_type), alignof(value_type)) on the referenced allocator object 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().
