SoftStoneDevelop/ArrayPool

A simple thread safety pool of arrays or wrapper on memory.

Array pool and memory owner:

A simple thread safety pool of arrays. If the array in the pool is not used for more than 60 seconds, then it will be deleted.

Direct Manual rent and return from pool:

auto pool = ArrayPool::ArrayPool<int>();
int realSize = 0;

auto arr = pool.Rent(10, realSize);
//arr array realSize equal to 10, because poll was empty when we rent him
pool.Return(arr);

auto arr2 = pool.Rent(5, realSize);
//arr array realSize is still equal to 10, because pool have free array with size 10
pool.Return(arr2);

using namespace std::literals::chrono_literals;
std::this_thread::sleep_for(120s);
//now the pool is empty, because arrays have not been used for too long

Rent and return memory wrapper(MemoryOwner) from wrapper factory:

auto pool = std::make_shared<ArrayPool::ArrayPool<int>>();
ArrayPool::MemoryOwnerFactory<int> memoryFactory(pool);

{
    ArrayPool::MemoryOwner<int> arr = memoryFactory.rentMemory(10);//rent newMemory from pool
}
//return memory to pool in destructor automatically

Rent and return memory wrapper(MemoryOwner*) from wrapper factory:

auto pool = std::make_shared<ArrayPool::ArrayPool<int>>();
ArrayPool::MemoryOwnerFactory<int> memoryFactory(pool);

ArrayPool::MemoryOwner<int>* arr = memoryFactory.newRentMemory(10);//rent newMemory from pool
delete arr;
//return memory to pool manual
