memory_resource_allocator Class Reference

Detailed Description

Wraps a memory_resource and makes it a RawAllocator.

Member Functions
	memory_resource_allocator (memory_resource *ptr) noexcept
void *	allocate_node (std::size_t size, std::size_t alignment)
void	deallocate_node (void *ptr, std::size_t size, std::size_t alignment) noexcept
std::size_t	max_alignment () const noexcept
memory_resource *	resource () const noexcept

Constructors

memory_resource_allocator()

memory_resource_allocator ( memory_resource *  ptr )

noexcept

Effects:

Creates it by giving it a pointer to the memory_resource.

Requires:

ptr must not be nullptr.

Member Functions

allocate_node()

void * allocate_node	(	std::size_t	size,
		std::size_t	alignment
	)

Effects:

Allocates a node by forwarding to the allocate() function.

Returns:

The node as returned by the memory_resource.

Throws:

Anything thrown by the allocate() function.

deallocate_node()

void deallocate_node ( void *  ptr, std::size_t  size, std::size_t  alignment  )

noexcept

Effects:

Deallocates a node by forwarding to the deallocate() function.

max_alignment()

std::size_t max_alignment ( ) const

noexcept

Returns:

The maximum alignment which is the maximum value of type std::size_t.

resource()

memory_resource * resource ( ) const

noexcept

Returns:

A pointer to the used memory_resource, this is never nullptr.
