bsl::map<int, pair<shared_ptr<Statistics>, shared_ptr<Collector<OsLinux>>>>::equal_range

Return a pair of iterators providing non‐modifiable access to the sequence of value_type objects in this map whose keys are equivalent to the specified key, where the first iterator is positioned at the start of the sequence and the second iterator is positioned one past the end of the sequence. The first returned iterator will be lower_bound(key), the second returned iterator will be upper_bound(key), and, if this map contains no value_type objects having keys equivalent to key, then the two returned iterators will have the same value. Note that although a map maintains unique keys, the range may contain more than one element, because a transparent comparator may have been supplied that provides a different (but compatible) partitioning of keys for LOOKUP_KEY as the comparisons used to order the keys in the map.
