Constructor & Destructor Documentation
◆ new_block_allocator() [1/5]
template<std::size_t DefaultBlockSize, typename GrowthMultiplier = no_growth_multiplier>
|
defaultnoexcept |
Default-constructs this new_block_allocator.
This is only enabled for non-dynamic new_block_allocators
◆ new_block_allocator() [2/5]
template<std::size_t DefaultBlockSize, typename GrowthMultiplier = no_growth_multiplier>
template<std::size_t USize = DefaultBlockSize, typename = std::enable_if_t<USize!=dynamic_size>>
|
explicit |
Constructs a new_block_allocator with the specified growth policy.
- Note
- This constructor only participates in overload resolution if the DefaultBlockSize is not
dynamic_size
- Parameters
-
growth the growth policy
◆ new_block_allocator() [3/5]
template<std::size_t DefaultBlockSize, typename GrowthMultiplier = no_growth_multiplier>
template<std::size_t USize = DefaultBlockSize, typename = std::enable_if_t<USize==dynamic_size>>
|
explicit |
Constructs a new_block_allocator with the default block_size.
- Note
- This constructor only participates in overload resolution if the DefaultBlockSize is
dynamic_size
- Parameters
-
block_size the default the block size
◆ new_block_allocator() [4/5]
template<std::size_t DefaultBlockSize, typename GrowthMultiplier = no_growth_multiplier>
|
default |
Move-constructs a new_block_allocator from another allocator.
- Parameters
-
other the other new_block_allocator to move
◆ new_block_allocator() [5/5]
template<std::size_t DefaultBlockSize, typename GrowthMultiplier = no_growth_multiplier>
|
default |
Copy-constructs a new_block_allocator from another allocator.
- Parameters
-
other the other new_block_allocator to copy
Member Function Documentation
◆ allocate_block()
template<std::size_t DefaultBlockSize, typename GrowthMultiplier = no_growth_multiplier>
|
noexcept |
Allocates a new'ed memory_block.
- Returns
- a null memory_block
◆ deallocate_block()
template<std::size_t DefaultBlockSize, typename GrowthMultiplier = no_growth_multiplier>
|
noexcept |
Deallocates a new'ed memory_block.
- Parameters
-
block the block to deallocate
◆ info()
template<std::size_t DefaultBlockSize, typename GrowthMultiplier = no_growth_multiplier>
|
noexcept |
Gets the info about this allocator.
This defaults to 'new_block_allocator'. Use a named_new_block_allocator to override this
- Returns
- the info for this allocator
◆ next_block_size()
template<std::size_t DefaultBlockSize, typename GrowthMultiplier = no_growth_multiplier>
|
noexcept |
Queries the next block size expected from this allocator.
- Returns
- the size of the next allocated block
◆ operator=() [1/2]
template<std::size_t DefaultBlockSize, typename GrowthMultiplier = no_growth_multiplier>
|
default |
Move-assigns a new_block_allocator from another allocator.
- Parameters
-
other the other new_block_allocator to move
- Returns
- reference to
(*this)
◆ operator=() [2/2]
template<std::size_t DefaultBlockSize, typename GrowthMultiplier = no_growth_multiplier>
|
default |
Copy-assigns a new_block_allocator from another allocator.
- Parameters
-
other the other new_block_allocator to copy
- Returns
- reference to
(*this)
