Declared in <bslstl_unorderedmap.h>

If a key equivalent to the specified key already exists in this unordered_map, assign the specified obj to the value associated with that key, and return a pair containing an iterator referring to the existing item and false. 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 a pair containing an iterator referring to the newly‐created entry and true.

If a key equivalent to the specified key already exists in this unordered_map, assign the specified obj to the value associated with that key, and return a pair containing an iterator referring to the existing item and false. Otherwise, insert into this map a newly‐created value_type object, constructed from (key, std::forward<BDE_OTHER_TYPE>(obj)...)), and return a pair containing an iterator referring to the newly‐created entry and true.

If a key equivalent to the specified key already exists in this unordered_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 unordered_map.
