Member Functions

try_allocate_node()

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

staticnoexcept

Returns:

The result of memory_pool_collection::try_allocate_node() or nullptr if the allocation size was too big.

try_allocate_array()

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

staticnoexcept

Returns:

The result of memory_pool_collection::try_allocate_array() or nullptr if the allocation size was too big.

try_deallocate_node()

static bool try_deallocate_node ( allocator_type &  state, void *  node, std::size_t  size, std::size_t  alignment  )

staticnoexcept

Effects:

Just forwards to memory_pool_collection::try_deallocate_node().

Returns:

Whether the deallocation was successful.

try_deallocate_array()

static bool try_deallocate_array ( allocator_type &  state, void *  array, std::size_t  count, std::size_t  size, std::size_t  alignment  )

staticnoexcept

Effects:

Forwards to memory_pool_collection::deallocate_array().

Returns:

Whether the deallocation was successful.
