I decided to throw out boost from my project. Any way to have best implement of container instead of ptr_map? As I know it holds a smart pointer as a value. Maybe QMap<Key, std::shared_ptr<Type*>> could do that?

    What’s wrong with std::map<Key, std::shared_ptr<Type>>? Advantages over QMap:

    • standard solution
    • has better worst-case time bounds (QMap is a skip list, so expected time bounds are the same)
    • 64-bit clean whenever the compiler/library is (QMap uses int for sizes)
    • interface is more similar to boost::ptr_map
