    • oppositeComparator

      public static <K> java.util.Comparator<K> oppositeComparator​(java.util.Comparator<K> c)
      Returns a comparator representing the opposite order of the given comparator.
      Parameters:
      c - a comparator.
      Returns:
      a comparator representing the opposite order of c.

    • asObjectComparator

      public static <K> java.util.Comparator<K> asObjectComparator​(java.util.Comparator<K> c)
      Returns a the comparator given unmodified. This method merely serves as a way to be compatible with primtive type-specific Comparators implementations, as they do have type-specific Comparators, but Object ones do not.
      Parameters:
      c - a comparator, or null.
      Returns:
      c, unmodified.
