allocator_traits< temporary_allocator > Class Reference

Detailed Description

Specialization of the allocator_traits for temporary_allocator classes.

Note

It is not allowed to mix calls through the specialization and through the member functions, i.e. temporary_allocator::allocate() and this allocate_node().

Typedefs
using	allocator_type = temporary_allocator
using	is_stateful = std::true_type

Static Functions
static void *	allocate_node (allocator_type &state, std::size_t size, std::size_t alignment)
static void *	allocate_array (allocator_type &state, std::size_t count, std::size_t size, std::size_t alignment)
static std::size_t	max_alignment (const allocator_type &) noexcept
static void	deallocate_node (const allocator_type &, void *, std::size_t, std::size_t) noexcept
static void	deallocate_array (const allocator_type &, void *, std::size_t, std::size_t, std::size_t) noexcept
static std::size_t	max_node_size (const allocator_type &state) noexcept
static std::size_t	max_array_size (const allocator_type &state) noexcept

Member Functions

allocate_node()

static void * allocate_node ( allocator_type &  state, std::size_t  size, std::size_t  alignment  )

static

Returns:

The result of temporary_allocator::allocate().

allocate_array()

static void * allocate_array ( allocator_type &  state, std::size_t  count, std::size_t  size, std::size_t  alignment  )

static

Returns:

The result of temporary_allocator::allocate().

deallocate_node()

static void deallocate_node ( const allocator_type &  , void *  , std::size_t  , std::size_t    )

staticnoexcept

Effects:

Does nothing besides bookmarking for leak checking, if that is enabled. Actual deallocation will be done automatically if the allocator object goes out of scope.

deallocate_array()

static void deallocate_array ( const allocator_type &  , void *  , std::size_t  , std::size_t  , std::size_t    )

staticnoexcept

Effects:

Does nothing besides bookmarking for leak checking, if that is enabled. Actual deallocation will be done automatically if the allocator object goes out of scope.

max_node_size()

static std::size_t max_node_size ( const allocator_type &  state )

staticnoexcept

Returns:

The maximum size which is memory_stack::next_capacity() of the internal stack.

max_array_size()

static std::size_t max_array_size ( const allocator_type &  state )

staticnoexcept

Returns:

The maximum size which is memory_stack::next_capacity() of the internal stack.

max_alignment()

static std::size_t max_alignment ( const allocator_type &  )

staticnoexcept

Returns:

The maximum possible value since there is no alignment restriction (except indirectly through memory_stack::next_capacity()).
