public static class Object2LongSortedMaps.EmptySortedMap<K>
extends Object2LongMaps.EmptyMap<K>
implements Object2LongSortedMap<K>, java.io.Serializable, java.lang.Cloneable
An immutable class representing an empty type-specific sorted map.

This class may be useful to implement your own in case you subclass a type-specific sorted map.

  • Method Details

    • comparator

      public java.util.Comparator<? super K> comparator()
      Description copied from interface: Object2LongSortedMap
      Returns the comparator associated with this sorted set, or null if it uses its keys' natural ordering.
      Specified by:
      comparator in interface Object2LongSortedMap<K>
      Specified by:
      comparator in interface java.util.SortedMap<K,​java.lang.Long>
      See Also:
      SortedMap.comparator()
    • object2LongEntrySet

      public ObjectSortedSet<Object2LongMap.Entry<K>> object2LongEntrySet()
      Description copied from interface: Object2LongMap
      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:
      object2LongEntrySet in interface Object2LongMap<K>
      Specified by:
      object2LongEntrySet in interface Object2LongSortedMap<K>
      Overrides:
      object2LongEntrySet in class Object2LongMaps.EmptyMap<K>
      Returns:
      a type-specific set view of the mappings contained in this map.

      @Deprecated public ObjectSortedSet<java.util.Map.Entry<K,​java.lang.Long>> entrySet()

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