public interface Object2CharMap<K>
A type-specific 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 Object2CharMap.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).

ObjectSet<java.util.Map.Entry<K,java.lang.Character>> entrySet()
Note that this specification strengthens the one given in Map.entrySet()
.
entrySet
in interface java.util.Map<K,java.lang.Character>
Map.entrySet()
ObjectSet<Object2CharMap.Entry<K>> object2CharEntrySet()
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).
entrySet()
ObjectSet<K> keySet()
Note that this specification strengthens the one given in Map.keySet()
.
keySet
in interface java.util.Map<K,java.lang.Character>

CharCollection values()
Note that this specification strengthens the one given in Map.values()
.
