std::experi...ol_resource(3) C++ Standard Libary std::experi...ol_resource(3) NAME std::experimental::pmr::unsynchronized_pool_resource - std::experimen- tal::pmr::unsynchronized_pool_resource Synopsis Defined in header <experimental/memory_resource> class unsynchronized_pool_resource : public (library fundamentals TS) memory_resource; The class std::experimental::pmr::unsynchronized_pool_resource is a general-purpose memory resource class with the following properties: * It owns the allocated memory and frees it on destruction, even if deallocate has not been called for some of the allocated blocks. * It consists of a collection of pools that serves request for different block sizes. Each pool manages a collection of chunks that are then divided into blocks of uniform size. * Calls to do_allocate are dispatched to the pool serving the smallest blocks accommodating the requested size. * Exhausting memory in the pool causes the next allocation request for that pool to allocate an additional chunk of memory from the upstream al- locator to replenish the pool. The chunk size obtained increases geometri- cally. * Allocations requests that exceed the largest block size are served from the upstream allocator directly. * The largest block size and maximum chunk size may be tuned by passing a std::experimental::pmr::pool_options struct to its constructor. unsynchronized_pool_resource is not thread-safe, and cannot be ac- cessed from multiple threads simultaneously; use synchronized_pool_resource if access from multiple threads is required. Member functions constructor constructs an unsynchronized_pool_resource (public member function) destructor destroys an unsynchronized_pool_resource, releas- ing all allocated [virtual] memory (virtual public member function) operator= copy assignment operator is deleted. unsynchro- nized_pool_resource [deleted] is not copy assignable (public member function) Public member functions release release all allocated memory (public member function) upstream_resource returns a pointer to the upstream memory resource (public member function) returns the options that control the pooling be- havior of this options resource (public member function) Protected member functions do_allocate allocate memory [virtual] (virtual protected member function) do_deallocate return memory to the pool [virtual] (virtual protected member function) do_is_equal compare for equality with another memory_resource [virtual] (virtual protected member function) Category: * Noindexed pages http://cppreference.com 2024.06.10 std::experi...ol_resource(3)
