    bslalg::BidirectionalLink* hint,

Description

If a key equivalent to the specified key already exists in this hash‐table, assign the specified obj to the value associated with that key, 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 key and obj, 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.

Return Value

pointer to the existing or newly created entry
