If a key equivalent to the specified key already exists in this _map, assign the specified obj to the value associated with that key, and return an iterator referring to the existing item. Otherwise, insert into this map a newly‐created value_type object constructed from (std::forward<KEY>(key), std::forward<BDE_OTHER_TYPE>(obj)...)), and return an iterator referring to the newly‐created entry. Use the specified hint as a starting point for checking to see if the key already in the map.
