Try to emplace an element with key using a placement hint.
Declared in <bdlc_flathashmap.h>
template<class... ARGS>
FlatHashMap<KEY, VALUE, HASH, EQUAL>::iterator
try_emplace(
const_iterator hint,
KEY const& key,
ARGS&&... args);If a key equivalent to the specified key already exists in this map, return an iterator referring to the existing item. Otherwise, insert into this map a newly-created value_type object, constructed from key and the specified args, and return an iterator referring to the newly-created entry. This method requires that the (template parameter) types KEY and VALUE are emplace-constructible from key and args respectively. For C++03, VALUE must also be copy-constructible.
iterator to the existing or newly inserted element
| Name | Description |
|---|---|
| hint | iterator hint (ignored) |
| key | key of the element to emplace |
| args | arguments forwarded to construct the mapped value |
