  • Method Details

    • natural

      public static <T> ElementOrderMethod<T> natural()
      Get the natural ordering method
      Type Parameters:
      T - the element type
      Returns:
      the natural ordering method

    • internal

      public static <T> ElementOrderMethod<T> internal()
      Get the internal ordering method. This represents the method of explicitly maintaining a map from the elements to long integers. Thus, it incurs a penalty in space and in lookups.
      Type Parameters:
      T - the element type
      Returns:
      the internal ordering method

    • comparator

      public static <T> ElementOrderMethod<T> comparator(Comparator<T> comparator)
      Get the comparator ordering method.
      Type Parameters:
      T - the element type
      Parameters:
      comparator - the actual comparator
      Returns:
      the comparator ordering method

    • guavaComparator

      public static <T> ElementOrderMethod<T> guavaComparator()
      Get the guava comparator ordering method.
      Type Parameters:
      T - the element type
      Returns:
      the comparator ordering method

    • comparator

      public Comparator<T> comparator()
      Get the comparator. Returns null if the method does not use an explicit comparator.
      Returns:
      the comparator or null if the method does not use an explicit comparator

    • getType

      public ElementOrderMethod.Type getType()
      Get the type
      Returns:
      the type
