  - comparator
```
public CharComparator comparator()
```
    Description copied from interface: Char2LongSortedMap
    
    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 Char2LongSortedMap
    
    Specified by:

  - char2LongEntrySet
```
public ObjectSortedSet<Char2LongMap.Entry> char2LongEntrySet()
```
    Description copied from interface: Char2LongMap
    
    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:
    
    char2LongEntrySet in interface Char2LongMap
    
    Specified by:
    
    char2LongEntrySet in interface Char2LongSortedMap
    
    Overrides:
    
    char2LongEntrySet in class Char2LongMaps.EmptyMap
    
    Returns:
    
    a type-specific set view of the mappings contained in this map.

@Deprecated
public ObjectSortedSet<Map.Entry<Character,Long>> entrySet()
