public interface Char2ObjectMap<V> extends Char2ObjectFunction<V>, Map<Character,V>
Map; provides some additional methods that use polymorphism to avoid (un)boxing, and handling of a default return value.
Besides extending the corresponding type-specific function, this interface strengthens entrySet(),
keySet() and values(). Maps returning entry sets of type Char2ObjectMap.FastEntrySet support also fast iteration.
A submap or subset may or may not have an independent default return value (which however must be initialized to the default return value of the originator).

entrySet インタフェース内 Map<Character,V>Map.entrySet()ObjectSet<Char2ObjectMap.Entry<V>> char2ObjectEntrySet()
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen entrySet()
so that it returns an ObjectSet
of objects of type Map.Entry (the latter makes it possible to
access keys and values with type-specific methods).
