  • Method Details

    • keySet

      public ObjectSortedSet<K> keySet()
      Returns a type-specific-set view of the keys of this map.

      The view is backed by the set returned by Map.entrySet(). Note that no attempt is made at caching the result of this method, as this would require adding some attributes that lightweight implementations would not need. Subclasses may easily override this policy by calling this method and caching the result, but implementors are encouraged to write more efficient ad-hoc implementations.

      The view is backed by the sorted set returned by Map.entrySet(). Note that no attempt is made at caching the result of this method, as this would require adding some attributes that lightweight implementations would not need. Subclasses may easily override this policy by calling this method and caching the result, but implementors are encouraged to write more efficient ad-hoc implementations.

      Overrides:
      keySet in class AbstractObject2ReferenceMap<K,​V>
      Returns:
      a sorted set view of the keys of this map; it may be safely cast to a type-specific interface.

    • values

      public ReferenceCollection<V> values()
      Returns a type-specific-set view of the values of this map.
