Method Detail

containsValue
public boolean containsValue(Object v)
- Specified by:
containsValue
in interfaceMap<K,V>
-
object2ReferenceEntrySet
public ObjectSet<Object2ReferenceMap.Entry<K,V>> object2ReferenceEntrySet()
Description copied from interface:Object2ReferenceMap
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 anObjectSet
of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).- Specified by:
object2ReferenceEntrySet
in interfaceObject2ReferenceMap<K,V>
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
entrySet
public ObjectSet<Map.Entry<K,V>> entrySet()
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 interfaceMap<K,V>
- Specified by:
entrySet
in interfaceObject2ReferenceMap<K,V>
- Returns:
- a set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
keySet
public ObjectSet<K> keySet()
Description copied from interface:Object2ReferenceMap
Note that this specification strengthens the one given in
Map.keySet()
.- Specified by:
keySet
in interfaceMap<K,V>
- Specified by:
keySet
in interfaceObject2ReferenceMap<K,V>
- Returns:
- a set view of the keys contained in this map.
- See Also:
Map.keySet()
-
values
public ReferenceCollection<V> values()
Description copied from interface:Object2ReferenceMap
Note that this specification strengthens the one given in
Map.values()
.- Specified by:
values
in interfaceMap<K,V>
- Specified by:
values
in interfaceObject2ReferenceMap<K,V>
- Returns:
- a set view of the values contained in this map.
- See Also:
Map.values()
-
hashCode
public int hashCode()
-
equals
public boolean equals(Object o)
-
getOrDefault
public V getOrDefault(Object key, V defaultValue)
- Specified by:

replaceAll
public void replaceAll(BiFunction<? super K,? super V,? extends V> function)
- Specified by:
replaceAll
in interfaceMap<K,V>
