Constructor & Destructor Documentation

null_block_allocator() [1/2]

bit::memory::null_block_allocator::null_block_allocator ( null_block_allocator &&  other )

defaultnoexcept

Move-constructs a null_block_allocator from another allocator.

Parameters

other

the other null_block_allocator to move

null_block_allocator() [2/2]

bit::memory::null_block_allocator::null_block_allocator ( const null_block_allocator &  other )

defaultnoexcept

Copy-constructs a null_block_allocator from another allocator.

Parameters

the other null_block_allocator to copy

Member Function Documentation

allocate_block()

owner<memory_block> bit::memory::null_block_allocator::allocate_block ( )

noexcept

Allocates a null memory_block.

Returns

a null memory_block

deallocate_block()

void bit::memory::null_block_allocator::deallocate_block ( owner< memory_block >  block )

noexcept

Deallocates a memory_block.

Parameters

block

the block to deallocate

info()

allocator_info bit::memory::null_block_allocator::info ( ) const

noexcept

Gets the info about this allocator.

This defaults to 'null_block_allocator'. Use a named_null_block_allocator to override this

Returns

the info for this allocator

next_block_size()

std::size_t bit::memory::null_block_allocator::next_block_size ( ) const

noexcept

Queries the next block size expected from this allocator.

Returns

the size of the next allocated block

operator=() [1/2]

null_block_allocator& bit::memory::null_block_allocator::operator= ( null_block_allocator &&  other )

defaultnoexcept

Move-assigns a null_block_allocator from another allocator.

Parameters

other

the other null_block_allocator to move

Returns

reference to (*this)

operator=() [2/2]

null_block_allocator& bit::memory::null_block_allocator::operator= ( const null_block_allocator &  other )

defaultnoexcept

Copy-assigns a null_block_allocator from another allocator.

Parameters

other

the other null_block_allocator to copy

Returns

reference to (*this)
