Detailed Description

template<std::size_t BlockSize, std::size_t Blocks = 1, std::size_t Align = alignof(std::max_align_t), typename Tag = void>
class bit::memory::static_block_allocator< BlockSize, Blocks, Align, Tag >

This is a block allocator that distributes blocks of memory stored statically.

This type is templated on both the size of the static block, and an additional Tag type that may be used to create individual instantiations

Note

Since this type creates static storage data, two instantiations with the same size/tag will point to the same data – hence the ability to use type-tagging to produce unique instances.

Template Parameters

BlockSize	the size of the static allocation
Blocks	the number of blocks
Align	the alignment of the blocks
Tag	the type used for a tag

Member Function Documentation

allocate_block()

template<std::size_t BlockSize, std::size_t Blocks = 1, std::size_t Align = alignof(std::max_align_t), typename Tag = void>

owner<memory_block> bit::memory::static_block_allocator< BlockSize, Blocks, Align, Tag >::allocate_block ( )

noexcept

Allocates a memory block of size Size.

Returns

a newly allocated memory_block

deallocate_block()

template<std::size_t BlockSize, std::size_t Blocks = 1, std::size_t Align = alignof(std::max_align_t), typename Tag = void>

void bit::memory::static_block_allocator< BlockSize, Blocks, Align, Tag >::deallocate_block ( owner< memory_block >  block )

noexcept

Deallocates a given memory_block.

Parameters

block

the block to deallocate

info()

template<std::size_t BlockSize, std::size_t Blocks = 1, std::size_t Align = alignof(std::max_align_t), typename Tag = void>

allocator_info bit::memory::static_block_allocator< BlockSize, Blocks, Align, Tag >::info ( ) const

noexcept

Gets the info about this allocator.

This defaults to 'static_block_allocator'. Use a named_static_block_allocator to override this

Returns

the info for this allocator

next_block_size()

template<std::size_t BlockSize, std::size_t Blocks = 1, std::size_t Align = alignof(std::max_align_t), typename Tag = void>

std::size_t bit::memory::static_block_allocator< BlockSize, Blocks, Align, Tag >::next_block_size ( ) const

noexcept

Queries the next block size expected from this allocator.

Returns

the size of the next allocated block

Parameters

other

the other allocator to move

Returns
