Synopses

Declared in <bslstl_unorderedset.h>

Return an iterator providing modifiable access to the value_type object in this unordered set that is equivalent to the specified key, if such an entry exists, and the past-the-end (end) iterator otherwise.

Return an iterator providing non-modifiable access to the value_type object in this unordered set that is equivalent to the specified key, if such an entry exists, and the past-the-end (end) iterator otherwise.

Return an iterator providing modifiable access to the value_type object in this unordered set that is equivalent to the specified key, if such an entry exists, and the past-the-end (end) iterator otherwise. The behavior is undefined unless key is equivalent to at most one element in this unordered set.
