    • singleton

      public static DoubleSortedSet singleton(double element)
      Returns a type-specific immutable sorted set containing only the specified element. The returned sorted set is serializable and cloneable.
      Parameters:
      element - the only element of the returned sorted set.
      Returns:
      a type-specific immutable sorted set containing just element.
    • singleton

      public static DoubleSortedSet singleton(double element, DoubleComparator comparator)
      Returns a type-specific immutable sorted set containing only the specified element, and using a specified comparator. The returned sorted set is serializable and cloneable.
      Parameters:
      element - the only element of the returned sorted set.
      comparator - the comparator to use in the returned sorted set.
      Returns:
      a type-specific immutable sorted set containing just element.
    • singleton

      public static DoubleSortedSet singleton(Object element)
      Returns a type-specific immutable sorted set containing only the specified element. The returned sorted set is serializable and cloneable.
      Parameters:
      element - the only element of the returned sorted set.
      Returns:
      a type-specific immutable sorted set containing just element.
    • singleton

      public static DoubleSortedSet singleton(Object element, DoubleComparator comparator)
      Returns a type-specific immutable sorted set containing only the specified element, and using a specified comparator. The returned sorted set is serializable and cloneable.
      Parameters:
      element - the only element of the returned sorted set.
      comparator - the comparator to use in the returned sorted set.
      Returns:
      a type-specific immutable sorted set containing just element.
    • synchronize

      public static DoubleSortedSet synchronize(DoubleSortedSet s)
      Returns a synchronized type-specific sorted set backed by the given type-specific sorted set.
      Parameters:
      s - the sorted set to be wrapped in a synchronized sorted set.
      Returns:
      a synchronized view of the specified sorted set.

    • synchronize

      public static DoubleSortedSet synchronize(DoubleSortedSet s, Object sync)
      Returns a synchronized type-specific sorted set backed by the given type-specific sorted set, using an assigned object to synchronize.
      Parameters:
      s - the sorted set to be wrapped in a synchronized sorted set.
      sync - an object that will be used to synchronize the access to the sorted set.
      Returns:
      a synchronized view of the specified sorted set.

    • unmodifiable

      public static DoubleSortedSet unmodifiable(DoubleSortedSet s)
      Returns an unmodifiable type-specific sorted set backed by the given type-specific sorted set.
      Parameters:
      s - the sorted set to be wrapped in an unmodifiable sorted set.
      Returns:
      an unmodifiable view of the specified sorted set.
