  - comparator
```
public CharComparator comparator()
```
    Description copied from interface: Char2CharSortedMap
    
    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 Char2CharSortedMap
    
    Specified by:
    
    comparator in interface java.util.SortedMap<java.lang.Character,java.lang.Character>
    
    See Also:
    
    SortedMap.comparator()
  - char2CharEntrySet
```
public ObjectSortedSet<Char2CharMap.Entry> char2CharEntrySet()
```
    Description copied from interface: Char2CharMap
    
    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 Char2CharMap.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).
