Declared in <bslstl_hashtable.h>

If a key equivalent to the specified key already exists in this hash‐table, load false into the specified isInsertedFlag and return a pointer to the existing entry. Otherwise, insert into this hash‐table a newly‐created value_type object, constructed from std::forward<KEY>(key) and the specified args, load true into isInsertedFlag and return a pointer to the newly created entry. Use the optionally specified hint as a starting place for the search for the existing key.
