Class Reference2ObjectMaps.EmptyMap<K,​V>

    • Method Detail

      • containsValue

        public boolean containsValue​(java.lang.Object v)
        Specified by:
        containsValue in interface java.util.Map<K,​V>
      • putAll

        public void putAll​(java.util.Map<? extends K,​? extends V> m)
        Specified by:
        putAll in interface java.util.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.

        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 java.util.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 java.util.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()
        Specified by:
        isEmpty in interface java.util.Map<K,​V>
