I think there is a much higher chance of a dev knowing > the semantics of list<unique_ptr<T>> than boost::ptr_list<T>. Boost include-only libraries are already a dependency, even for 2Geom. The overhead of learning boost::ptr_list when you already know how to use std::list is minimal compared to the overhead of writing boilerplate destructor code on every object that contains an std::list of pointers. std::unique_ptr is only available in C++11 so we cannot use it yet, and std::auto_ptr cannot be put into containers. Here are some examples. std::ptr_list<Object> list, list2 list.push_back(new Object(1, 2, 3)); list.push_back(new DerivedObject()); list.push_back(new Object(3, 2, 1)); list.erase(list.begin()); // calls desctructor std::auto_ptr<Object> x = list.release(list.begin()); // if you want to remove an object without destroying it Regards, Krzysztof ------------------------------------------------------------------------------ CenturyLink Cloud: The Leader in Enterprise Cloud Services.
