#include<filesystem> 在C++中,<memory>是一个标准库头文件,它包含了std::shared_ptr和std::unique_ptr类,这是一个智能指针库。要在C++代码中包含这个库,你需要在文件的开头添加以下代码: 代码语言:cpp 复制 #include<memory> 在C++中,<functional>是一个标准库头文件,它包含了std::function类,这是一个函数...

It comes with a fake implementation of aunique_ptrfor C++98. The goals of this minimal shared_ptr are: to replace the C++11 std::shared_ptr and boost::shared_ptr where they are not available to be a header only implementation to keep dependencies to a minimum (STL) ...
继承自std::enable_shared_from_this<T>的类能够在其自身实例中通过std::shared_from_this方法创建一个指向自己的std::shared_ptr<T>智能指针。 从一个裸指针创建多个std::shared_ptr<T>实例会造成严重的后果,其行为是未定义的。 std::enable_shared_from_this<T>实际包含了一个用于指向对象自身的std::weak...
It should be used to manage any dynamically allocated object that is not shared by multiple objects. That is, std::unique_ptr should completely own the object it manages, not share that ownership with other classes. std::unique_ptr lives in the <memory> header. Let’s take a look at a...
