Detailed Description

template<class tag, uint64_t mem_size>
class object::RawStorageAllocator< tag, mem_size >

Allocator allocating from RawStorage.

Template Parameters:
tag Type not used for internal purposes but to allow multiple seperated RawStorage pools to be used for allocation. Allocators with the same tag share one RawStorage object (implemented as singleton).
mem_size Size of RawStorage memory pool
