  • Method Details

    • 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>

    • object2ReferenceEntrySet

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

      Specified by:
      object2ReferenceEntrySet in interface Object2ReferenceMap<K,​V>
      Returns:
      a type-specific set view of the mappings contained in this map.
      See Also:
      Map.entrySet()

    • entrySet

      public it.unimi.dsi.fastutil.objects.ObjectSet<java.util.Map.Entry<K,​V>> entrySet()
      Returns a set view of the mappings contained in this map.
      Specified by:
      entrySet in interface java.util.Map<K,​V>
      Specified by:
      entrySet in interface Object2ReferenceMap<K,​V>
      Returns:
      a set view of the mappings contained in this map.
      See Also:
      Map.entrySet()

    • keySet

      public it.unimi.dsi.fastutil.objects.ObjectSet<K> keySet()
      Description copied from interface: Object2ReferenceMap
      Specified by:
      keySet in interface java.util.Map<K,​V>
      Specified by:
      keySet in interface Object2ReferenceMap<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
