#include#include class MyObject { public: MyObject() { std::cout << "MyObject created!\n"; } ~MyObject() { std::cout << "MyObject destroyed!\n"; } }; int main() { boost::ptr_map refMap; std::unique_ptr obj1(new MyObject()); std::unique_ptr obj2(new MyObject()); refMap.insert(1, obj1.release()); refMap.insert(2, obj2.release()); refMap.erase(1); refMap.erase(2); }
#includeIn this example, we create a RefPtr Map and insert 10 MyObject instances into the map. As we create each MyObject instance, we increment its reference count by 1. When the map goes out of scope, the reference counts are automatically decremented and any objects with a reference count of 0 are destroyed. In conclusion, the RefPtr Map is a useful container class for managing reference-counted objects in C++. It is part of the Boost C++ Libraries, which provide a broad range of high-quality libraries for C++ programming.#include class MyObject { public: MyObject() { std::cout << "MyObject created!\n"; } ~MyObject() { std::cout << "MyObject destroyed!\n"; } }; int main() { boost::ptr_map refMap; for (int i = 0; i < 10; ++i) { std::unique_ptr obj(new MyObject()); refMap.insert(i, obj.release()); } }
