  • Method Details

    • comparator

      public java.util.Comparator<? super K> comparator()
      Description copied from interface: Reference2DoubleSortedMap
      Returns the comparator associated with this sorted set, or null if it uses its keys' natural ordering.
      Specified by:
      comparator in interface Reference2DoubleSortedMap<K>
      Specified by:
      comparator in interface java.util.SortedMap<K,​java.lang.Double>
      See Also:
      SortedMap.comparator()

    • reference2DoubleEntrySet

      public it.unimi.dsi.fastutil.objects.ObjectSortedSet<Reference2DoubleMap.Entry<K>> reference2DoubleEntrySet()
      Description copied from interface: Reference2DoubleMap
      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:
      reference2DoubleEntrySet in interface Reference2DoubleMap<K>
      Specified by:
      reference2DoubleEntrySet in interface Reference2DoubleSortedMap<K>
      Overrides:
      reference2DoubleEntrySet in class Reference2DoubleMaps.Singleton<K>
      Returns:
      a type-specific set view of the mappings contained in this map.

      Returns a set view of the mappings contained in this map.
