我有一个类,看起来像这样：
@H_301_2@template<typename T>
using VectorPtr=std::vector<std::unique_ptr<T>>;
template<typename T>
using VectorRawPtr=std::vector<T*>;
class ItemsSet{ // <-- Compiler say this line contans an error 0_o ?
public:
ItemsSet(VectorPtr<Item>& items);
~ItemsSet() = default;
VectorRawPtr<Item> GetItems();
VectorRawPtr<Item> GetSuitableItemsForPeriod(const IPeriod &period);
double CalculateTotal();
private:
VectorPtr<Item> _items;
};
构造函数看起来像：
@H_301_2@ItemsSet::ItemsSet(VectorPtr<Item> & items) { for(auto &itm: items){ _items.emplace_back(std::move(itm)); } } @H_301_2@/usr/lib/gcc/x86_64-pc-cygwin/5.4.0/include/c++/bits/stl_construct.h: In instantiation of 'void std::_Construct(_T1*,_Args&& ...)
