Method Details

containsValue

public boolean containsValue(Object v)

Specified by:

containsValue in interface Map<K,V>

putAll

public void putAll(Map<? extends K,? extends V> m)

Specified by:

putAll in interface Map<K,V>

reference2ObjectEntrySet

public ObjectSet<Reference2ObjectMap.Entry<K,V>> reference2ObjectEntrySet()

Description copied from interface: Reference2ObjectMap

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 an ObjectSet of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).

Specified by:

reference2ObjectEntrySet in interface Reference2ObjectMap<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 interface Map<K,V>

Specified by:

entrySet in interface Reference2ObjectMap<K,V>

Returns:

a set view of the mappings contained in this map.

See Also:

Map.entrySet()

keySet

public ReferenceSet<K> keySet()

Description copied from interface: Reference2ObjectMap

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

Specified by:

keySet in interface Map<K,V>

Specified by:

keySet in interface Reference2ObjectMap<K,V>

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

values

public ObjectCollection<V> values()

Description copied from interface: Reference2ObjectMap

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

Specified by:

values in interface Map<K,V>

Specified by:

values in interface Reference2ObjectMap<K,V>

Returns:

a set view of the values contained in this map.

See Also:

Map.values()

isEmpty

public boolean isEmpty()
