  • Method Details

    • comparator

      public it.unimi.dsi.fastutil.longs.LongComparator comparator()
      Description copied from interface: Long2ReferenceSortedMap
      Returns the comparator associated with this sorted set, or null if it uses its keys' natural ordering.
      Specified by:
      comparator in interface Long2ReferenceSortedMap<V>
      Specified by:
      comparator in interface java.util.SortedMap<java.lang.Long,​V>
      See Also:
      SortedMap.comparator()

    • long2ReferenceEntrySet

      public it.unimi.dsi.fastutil.objects.ObjectSortedSet<Long2ReferenceMap.Entry<V>> long2ReferenceEntrySet()
      Description copied from interface: Long2ReferenceMap
      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:
      long2ReferenceEntrySet in interface Long2ReferenceMap<V>
      Specified by:
      long2ReferenceEntrySet in interface Long2ReferenceSortedMap<V>
      Overrides:
      long2ReferenceEntrySet in class Long2ReferenceMaps.Singleton<V>
      Returns:
      a type-specific set view of the mappings contained in this map.
