allocate()

template<typename Type>

std::uint8_t * xrpl::SlabAllocatorSet< Type >::allocate ( std::size_t extra )

noexcept

Returns a suitably aligned pointer, if one is available.

Parameters

extra

The number of extra bytes, above and beyond the size of the object, that should be returned by the allocator.

Returns

a pointer to a block of memory, or nullptr if the allocator can't satisfy this request.

Definition at line 356 of file SlabAllocator.h.

deallocate()

template<typename Type>

bool xrpl::SlabAllocatorSet< Type >::deallocate ( std::uint8_t * ptr )

noexcept

Returns the memory block to the allocator.

Parameters

ptr	A pointer to a memory block.

Returns

true if this memory block belonged to one of the allocators in this set and has been released; false otherwise.
