mah*_*nya 6 c++ thread-safety object-pooling
我需要创建一个套接字连接池,它将被提供给多个工作线程.是否有一个线程安全的对象池实现,其功能类似于Apache Commons GenericObjectPool?
我通常使用TBB来实现线程安全的可伸缩池.
template <typename T>
class object_pool
{
std::shared_ptr<tbb::concurrent_bounded_queue<std::shared_ptr<T>>> pool_;
public:
object_pool()
: pool_(new tbb::concurrent_bounded_queue<std::shared_ptr<T>>()){}
// Create overloads with different amount of templated parameters.
std::shared_ptr<T> create()
{
std::shared_ptr<T> obj;
if(!pool_->try_pop(obj))
obj = std::make_shared<T>();
// Automatically collects obj.
return std::shared_ptr<T>(obj.get(), [=](T*){pool_->push(obj);});
}
};
