memory_resource_adapter< RawAllocator > Class Template Reference

Detailed Description

template<class RawAllocator>
class foonathan::memory::memory_resource_adapter< RawAllocator >

Wraps a RawAllocator and makes it a memory_resource.

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

Member Functions
	memory_resource_adapter (allocator_type &&other) noexcept
void *	allocate (std::size_t bytes, std::size_t alignment=max_alignment)
void	deallocate (void *p, std::size_t bytes, std::size_t alignment=max_alignment)
bool	is_equal (const memory_resource &other) const noexcept
allocator_type &	get_allocator () noexcept

Constructors

memory_resource_adapter()

memory_resource_adapter ( allocator_type &&  other )

noexcept

Effects:

Creates the resource by moving in the allocator.

Member Functions

get_allocator() [1/2]

allocator_type & get_allocator ( )

noexcept

Returns:

A reference to the wrapped allocator.

get_allocator() [2/2]

const allocator_type & get_allocator ( ) const

noexcept

Returns:

A reference to the wrapped allocator.

do_allocate()

void * do_allocate ( std::size_t  bytes, std::size_t  alignment  )

overrideprotected

Effects:

Allocates raw memory with given size and alignment. It forwards to allocate_node() or allocate_array() depending on the size.

Returns:

The new memory as returned by the RawAllocator.

Throws:

Anything thrown by the allocation function.

do_deallocate()

void do_deallocate ( void *  p, std::size_t  bytes, std::size_t  alignment  )

overrideprotected

Effects:

Deallocates memory previously allocated by do_allocate. It forwards to deallocate_node() or deallocate_array() depending on the size.

Throws:

Nothing.

do_is_equal()

bool do_is_equal ( const memory_resource &  other ) const

overrideprotectednoexcept

Returns:

Whether or not *this is equal to other by comparing the addresses.
