equal_range overloads
Declared in <bslstl_multimap.h>
Return a pair of iterators providing modifiable access to the sequence of value_type objects in this multimap whose keys are equivalent to the specified key, where the first iterator is positioned at the start of the sequence and the second 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 multimap contains no value_type object with an equivalent key, then the two returned iterators will have the same value.
bsl::pair<iterator, iterator>
equal_range(key_type const& key);Return a pair of iterators providing non-modifiable access to the sequence of value_type objects in this multimap 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 multimap contains no value_type objects having keys equivalent to key, then the two returned iterators will have the same value.
pair<const_iterator, const_iterator>
equal_range(key_type const& key) const;Return a pair of iterators providing modifiable access to the sequence of value_type objects in this multimap whose keys are equivalent to the specified key, where the first iterator is positioned at the start of the sequence and the second 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 multimap contains no value_type object with an equivalent key, then the two returned iterators will have the same value.
