  • Method Details

    • comparator

      public java.util.Comparator<? super K> comparator()
      Description copied from interface: Object2ByteSortedMap
      Returns the comparator associated with this sorted set, or null if it uses its keys' natural ordering.
      Specified by:
      comparator in interface Object2ByteSortedMap<K>
      Specified by:
      comparator in interface java.util.SortedMap<K,​java.lang.Byte>
      See Also:
      SortedMap.comparator()

    • object2ByteEntrySet

      public it.unimi.dsi.fastutil.objects.ObjectSortedSet<Object2ByteMap.Entry<K>> object2ByteEntrySet()
      Description copied from interface: Object2ByteMap
      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:
      object2ByteEntrySet in interface Object2ByteMap<K>
      Specified by:
      object2ByteEntrySet in interface Object2ByteSortedMap<K>
      Overrides:
      object2ByteEntrySet in class Object2ByteMaps.EmptyMap<K>
      Returns:
      a type-specific set view of the mappings contained in this map.

      Map.entrySet()

    • entrySet

      @Deprecated public it.unimi.dsi.fastutil.objects.ObjectSortedSet<java.util.Map.Entry<K,​java.lang.Byte>> entrySet()
      Deprecated.
      Please use the corresponding type-specific method instead.
      Returns a sorted-set view of the mappings contained in this map.
