Detailed Description
template<typename T, typename Policy = standard_alloc_policy<T>, typename Traits = object_traits<T>>
class pmem::obj::allocator< T, Policy, Traits >
(EXPERIMENTAL) Encapsulates the information about the persistent memory allocation model using PMDK's libpmemobj.
This information includes the knowledge of the pointer type, their difference type, the type of the size of objects in this allocation model as well as memory allocation and deallocation primitives.
The documentation for this class was generated from the following file:
- libpmemobj++/allocator.hpp
