allocator_traits< memory_stack< BlockAllocator > > Class Template Reference

Detailed Description

template<class BlockAllocator>
class foonathan::memory::allocator_traits< memory_stack< BlockAllocator > >

Specialization of the allocator_traits for memory_stack classes.

Note

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

Member Functions

allocate_node()

template<class BlockAllocator>

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

static

Returns:

The result of allocate().

allocate_array()

template<class BlockAllocator>

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

static

Returns:

The result of allocate().

deallocate_node()

template<class BlockAllocator>

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

staticnoexcept

Effects:

Does nothing besides bookmarking for leak checking, if that is enabled. Actual deallocation can only be done via unwind().

deallocate_array()

template<class BlockAllocator>

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

staticnoexcept

Effects:

Does nothing besides bookmarking for leak checking, if that is enabled. Actual deallocation can only be done via unwind().

max_node_size()

template<class BlockAllocator>

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

staticnoexcept

Returns:

The maximum size which is next_capacity().

max_array_size()

template<class BlockAllocator>

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

staticnoexcept

Returns:

The maximum size which is next_capacity().

max_alignment()

template<class BlockAllocator>

static std::size_t max_alignment ( const allocator_type & )

staticnoexcept

Returns:

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