  - comparator
```
public DoubleComparator comparator()
```
    Description copied from interface: Double2ReferenceSortedMap
    
    Returns the comparator associated with this sorted set, or null if it uses its keys' natural ordering.
    Note that this specification strengthens the one given in SortedMap.comparator().
    
    Specified by:
    
    comparator in interface Double2ReferenceSortedMap<V>
    
    Specified by:
    
    comparator in interface SortedMap<Double,V>

  - double2ReferenceEntrySet
```
public ObjectSortedSet<Double2ReferenceMap.Entry<V>> double2ReferenceEntrySet()
```
    Description copied from interface: Double2ReferenceMap
    
    Returns a type-specific set view of the mappings contained in this map.
    This method is necessary because there is no inheritance along type parameters: it is thus impossible to strengthen Map.entrySet() so that it returns an ObjectSet of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).
    
    Specified by:
    
    double2ReferenceEntrySet in interface Double2ReferenceMap<V>
    
    Specified by:
    
    double2ReferenceEntrySet in interface Double2ReferenceSortedMap<V>
    
    Overrides:
    
    double2ReferenceEntrySet in class Double2ReferenceMaps.Singleton<V>
    
    Returns:
    
    a type-specific set view of the mappings contained in this map.
