BloombergLP::bslstl::HashTable<UnorderedMapKeyConfiguration<basic_string<char> const, pair<basic_string<char> const, Json>>, TransparentHash, TransparentEqualTo, allocator<pair<basic_string<char> const, Json>>>::insertOrAssign

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.
