  Comparator<Optional<T>> emptiesFirst(Comparator<? super T>)
   | 
  Returns a comparator of Optional values which treats Optional.empty as less
 than all other values, and orders the rest using {@code valueComparator} on the contained
 value. | 
  
  
  Comparator<Optional<T>> emptiesLast(Comparator<? super T>)
   | 
  Returns a comparator of Optional values which treats Optional.empty as greater
 than all other values, and orders the rest using {@code valueComparator} on the contained
 value. | 
  
  
  (Collector<T, ?, List<T>>) greatest(int, Comparator<?, super, T>)
   | 
  Returns a {@code Collector} that returns the {@code k} greatest (relative to the specified
 {@code Comparator}) input elements, in descending order, as an unmodifiable {@code List}. | 
  
  
  (Collector<T, ?, List<T>>) least(int, Comparator<?, super, T>)
   | 
  Returns a {@code Collector} that returns the {@code k} smallest (relative to the specified
 {@code Comparator}) input elements, in ascending order, as an unmodifiable {@code List}. |
