allocator_traits< iteration_allocator< N, BlockAllocator > > Class Template Reference

Detailed Description

template<std::size_t N, class BlockAllocator>
class foonathan::memory::allocator_traits< iteration_allocator< N, BlockAllocator > >

Specialization of the allocator_traits for iteration_allocator.

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

Member Functions

◆ allocate_node()

static void* allocate_node ( allocator_type state,
std::size_t  size,
std::size_t  alignment 
)
static
Returns:
The result of iteration_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 memory_stack::allocate().

◆ deallocate_node()

static void deallocate_node ( allocator_type ,
void *  ,
std::size_t  ,
std::size_t   
)
staticnoexcept
Effects:
Does nothing. Actual deallocation can only be done via memory_stack::unwind().

◆ deallocate_array()

static void deallocate_array ( allocator_type ,
void *  ,
std::size_t  ,
std::size_t  ,
std::size_t   
)
staticnoexcept
Effects:
Does nothing. Actual deallocation can only be done via memory_stack::unwind().

◆ max_node_size()

static std::size_t max_node_size ( const allocator_type state)
staticnoexcept
Returns:
The maximum size which is iteration_allocator::capacity_left().

◆ max_array_size()

static std::size_t max_array_size ( const allocator_type state)
staticnoexcept
Returns:
The maximum size which is iteration_allocator::capacity_left().

◆ 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()).
