Method Detail

containsValue

public boolean containsValue(char v)
Specified by:
containsValue in interface Object2CharMap<K>
See Also:
Map.containsValue(Object)

containsValue

public boolean containsValue(Object ov)
Specified by:
containsValue in interface Map<K,Character>

putAll

public void putAll(Map<? extends K,? extends Character> m)
Specified by:
putAll in interface Map<K,Character>

object2CharEntrySet

public ObjectSet<Object2CharMap.Entry<K>> object2CharEntrySet()
Description copied from interface: Object2CharMap
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 Object2CharMap.entrySet() so that it returns an ObjectSet of objects of type Object2CharMap.Entry (the latter makes it possible to access keys and values with type-specific methods).

Specified by:
object2CharEntrySet in interface Object2CharMap<K>
Returns:
a type-specific set view of the mappings contained in this map.
See Also:
Object2CharMap.entrySet()

keySet

public ObjectSet<K> keySet()
Description copied from interface: Object2CharMap
Returns a set view of the keys contained in this map.

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

Specified by:
keySet in interface Object2CharMap<K>
Specified by:
keySet in interface Map<K,Character>
Returns:
a set view of the keys contained in this map.
See Also:
Map.keySet()

values

public CharCollection values()
Description copied from interface: Object2CharMap
Returns a set view of the values contained in this map.

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

Specified by:
values in interface Object2CharMap<K>
Specified by:
values in interface Map<K,Character>
Returns:
a set view of the values contained in this map.
See Also:
Map.values()

isEmpty

public boolean isEmpty()
Specified by:
isEmpty in interface Map<K,Character>

entrySet

public ObjectSet<Map.Entry<K,Character>> entrySet()
Description copied from interface: Object2CharMap
Returns a set view of the mappings contained in this map.

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

Specified by:
entrySet in interface Object2CharMap<K>
Specified by:
entrySet in interface Map<K,Character>
Returns:
a set view of the mappings contained in this map.
See Also:
Map.entrySet()

hashCode

public int hashCode()
Specified by:
hashCode in interface Map<K,Character>
Overrides:
hashCode in class Object

equals

public boolean equals(Object o)
Specified by:
equals in interface Map<K,Character>
Overrides:
equals in class Object

toString

public String toString()
Overrides:
toString in class Object
