| template <class... Args> iterator emplace_hint( const_iterator hint, Args&&... args ); |
（C++11 起） | |
插入一个新元素的容器，使用
hint一个建议，其中的元素。该元件是构成在就地，即没有复制或移动操作进行。 The constructor of the element is called with exactly the same arguments as supplied to the function, forwarded with std::forward<Args>(args)....原文：
Inserts a new element to the container, using
hint as a suggestion where the element should go. The element is constructed in-place, i.e. no copy or move operations are performed. The constructor of the element is called with exactly the same arguments as supplied to the function, forwarded with std::forward<Args>(args)....If rehashing occurs due to the insertion, all iterators are invalidated. Otherwise iterators are not affected. References are not invalidated. Rehashing occurs only if the new number of elements is higher than max_load_factor()*bucket_count().
