public static class Reference2FloatSortedMaps.EmptySortedMap<K>
extends Reference2FloatMaps.EmptyMap<K>
implements Reference2FloatSortedMap<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: Reference2FloatSortedMap
      Returns the comparator associated with this sorted set, or null if it uses its keys' natural ordering.
      Specified by:
      comparator in interface Reference2FloatSortedMap<K>
      Specified by:
      comparator in interface java.util.SortedMap<K,​java.lang.Float>
      See Also:
      SortedMap.comparator()
    • reference2FloatEntrySet

      public ObjectSortedSet<Reference2FloatMap.Entry<K>> reference2FloatEntrySet()
      Description copied from interface: Reference2FloatMap
      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:
      reference2FloatEntrySet in interface Reference2FloatMap<K>
      Specified by:
      reference2FloatEntrySet in interface Reference2FloatSortedMap<K>
      Overrides:
      reference2FloatEntrySet in class Reference2FloatMaps.EmptyMap<K>
      Returns:
      a type-specific set view of the mappings contained in this map.

    • entrySet

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

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