public interface Reference2ObjectSortedMap<K,​V>
extends Reference2ObjectMap<K,​V>, java.util.SortedMap<K,​V>
A type-specific SortedMap; provides some additional methods that use polymorphism to avoid (un)boxing.

Additionally, this interface strengthens entrySet(), keySet(), values(), comparator(), SortedMap.subMap(Object,Object), SortedMap.headMap(Object) and SortedMap.tailMap(Object).
