public abstract class ImmutableSortedSet<E>
extends ImmutableSet<E>
implements NavigableSet<E>
```
A NavigableSet whose contents will never change, with many other important properties detailed at ImmutableCollection.
Warning: as with any sorted collection, you are strongly advised not to use a Comparator or Comparable type whose comparison behavior is inconsistent with equals. That is, a.compareTo(b) or comparator.compare(a, b) should equal zero if and only if a.equals(b). If this advice is not followed, the resulting collection will not correctly obey its specification.

    Returns an immutable sorted set containing the given elements sorted by their natural ordering. When multiple elements are equivalent according to Comparable.compareTo(T), only the first one specified is included.

  - copyOf
```
public static <E extends Comparable<? super E>> ImmutableSortedSet<E> copyOf(E[] elements)
```
    Returns an immutable sorted set containing the given elements sorted by their natural ordering. When multiple elements are equivalent according to Comparable.compareTo(T), only the first one specified is included.

    Since:

  - copyOf
```
public static <E> ImmutableSortedSet<E> copyOf(Iterable<? extends E> elements)
```
    Returns an immutable sorted set containing the given elements sorted by their natural ordering. When multiple elements are equivalent according to compareTo(), only the first one specified is included. To create a copy of a SortedSet that preserves the comparator, call copyOfSorted(java.util.SortedSet<E>) instead. This method iterates over elements at most once.
    Note that if s is a Set<String>, then ImmutableSortedSet.copyOf(s) returns an ImmutableSortedSet<String> containing each of the strings in s, while ImmutableSortedSet.of(s) returns an ImmutableSortedSet<Set<String>> containing one element (the given set itself).
    Despite the method name, this method attempts to avoid actually copying the data when it is safe to do so. The exact circumstances under which a copy will or will not be performed are undocumented and subject to change.
    This method is not type-safe, as it may be called on elements that are not mutually comparable.
    
    Throws:
    
    ClassCastException - if the elements are not mutually comparable
    
    NullPointerException - if any of elements is null
  - copyOf
```
public static <E> ImmutableSortedSet<E> copyOf(Collection<? extends E> elements)
```
    Returns an immutable sorted set containing the given elements sorted by their natural ordering. When multiple elements are equivalent according to compareTo(), only the first one specified is included. To create a copy of a SortedSet that preserves the comparator, call copyOfSorted(java.util.SortedSet<E>) instead. This method iterates over elements at most once.
    Note that if s is a Set<String>, then ImmutableSortedSet.copyOf(s) returns an ImmutableSortedSet<String> containing each of the strings in s, while ImmutableSortedSet.of(s) returns an ImmutableSortedSet<Set<String>> containing one element (the given set itself).
    Note: Despite what the method name suggests, if elements is an ImmutableSortedSet, it may be returned instead of a copy.
    This method is not type-safe, as it may be called on elements that are not mutually comparable.
    This method is safe to use even when elements is a synchronized or concurrent collection that is currently being modified by another thread.
    
    Type Parameters:

    Parameters:

    Returns an immutable sorted set containing the given elements sorted by the given Comparator. When multiple elements are equivalent according to compare(), only the first one specified is included. This method iterates over elements at most once.
    Despite the method name, this method attempts to avoid actually copying the data when it is safe to do so. The exact circumstances under which a copy will or will not be performed are undocumented and subject to change.

  - copyOfSorted
```
public static <E> ImmutableSortedSet<E> copyOfSorted(SortedSet<E> sortedSet)
```
    Returns an immutable sorted set containing the elements of a sorted set, sorted by the same Comparator. That behavior differs from copyOf(Iterable), which always uses the natural ordering of the elements.
    Despite the method name, this method attempts to avoid actually copying the data when it is safe to do so. The exact circumstances under which a copy will or will not be performed are undocumented and subject to change.
    This method is safe to use even when sortedSet is a synchronized or concurrent collection that is currently being modified by another thread.
    
    Throws:
    
    NullPointerException - if sortedSet or any of its elements is null
  - orderedBy
```
public static <E> ImmutableSortedSet.Builder<E> orderedBy(Comparator<E> comparator)
```
    Returns a builder that creates immutable sorted sets with an explicit comparator. If the comparator has a more general type than the set being generated, such as creating a SortedSet<Integer> with a Comparator<Number>, use the ImmutableSortedSet.Builder constructor instead.
    
    Throws:
    
    NullPointerException - if comparator is null
  - reverseOrder
```
public static <E extends Comparable<?>> ImmutableSortedSet.Builder<E> reverseOrder()
```
    Returns a builder that creates immutable sorted sets whose elements are ordered by the reverse of their natural ordering.
  - naturalOrder
```
public static <E extends Comparable<?>> ImmutableSortedSet.Builder<E> naturalOrder()
```
    Returns a builder that creates immutable sorted sets whose elements are ordered by their natural ordering. The sorted sets use Ordering.natural() as the comparator. This method provides more type-safety than builder(), as it can be called only for classes that implement Comparable.
  - comparator
```
public Comparator<? super E> comparator()
```
    Returns the comparator that orders the elements, which is Ordering.natural() when the natural ordering of the elements is used. Note that its behavior is not consistent with SortedSet.comparator(), which returns null to indicate natural ordering.
    
    Specified by:
    
    comparator in interface SortedSet<E>
    
    Returns:
    
    the comparator used to order the elements in this set, or null if this set uses the natural ordering of its elements
  - iterator
```
public abstract UnmodifiableIterator<E> iterator()
```
    Description copied from class: ImmutableCollection
    
    Returns an unmodifiable iterator across the elements in this collection.
    
    Specified by:
    
    iterator in interface Collection<E>
    
    Specified by:
    
    iterator in interface Iterable<E>
    
    Specified by:
    
    iterator in interface NavigableSet<E>
    
    Specified by:
    
    iterator in interface Set<E>
    
    Specified by:
    
    iterator in class ImmutableSet<E>
    
    Returns:
    
    an iterator over the elements contained in this collection
  - headSet
```
public ImmutableSortedSet<E> headSet(E toElement)
```
    Returns a view of the portion of this set whose elements are strictly less than toElement. The returned set is backed by this set, so changes in the returned set are reflected in this set, and vice-versa. The returned set supports all optional set operations that this set supports.
    The returned set will throw an IllegalArgumentException on an attempt to insert an element outside its range.
    Equivalent to headSet(toElement, false).
    This method returns a serializable ImmutableSortedSet.
    The SortedSet.headSet(E) documentation states that a subset of a subset throws an IllegalArgumentException if passed a toElement greater than an earlier toElement. However, this method doesn't throw an exception in that situation, but instead keeps the original toElement.
    
    Specified by:
    
    headSet in interface NavigableSet<E>

    headSet in interface SortedSet<E>
    
    Parameters:
    
    toElement - high endpoint (exclusive) of the returned set
    
    Returns:
    
    a view of the portion of this set whose elements are strictly less than toElement
  - headSet
```
public ImmutableSortedSet<E> headSet(E toElement,
                                     boolean inclusive)
```
    Description copied from interface: java.util.NavigableSet
    
    Returns a view of the portion of this set whose elements are less than (or equal to, if inclusive is true) toElement. The returned set is backed by this set, so changes in the returned set are reflected in this set, and vice-versa. The returned set supports all optional set operations that this set supports.
    The returned set will throw an IllegalArgumentException on an attempt to insert an element outside its range.
    
    Specified by:
    
    headSet in interface NavigableSet<E>
    
    Parameters:
    
    toElement - high endpoint of the returned set
    
    inclusive - true if the high endpoint is to be included in the returned view
    
    Returns:
    
    a view of the portion of this set whose elements are less than (or equal to, if inclusive is true) toElement
    
    Since:
    
    12.0
  - subSet
```
public ImmutableSortedSet<E> subSet(E fromElement,
                                    E toElement)
```
    Returns a view of the portion of this set whose elements range from fromElement, inclusive, to toElement, exclusive. (If fromElement and toElement are equal, the returned set is empty.) The returned set is backed by this set, so changes in the returned set are reflected in this set, and vice-versa. The returned set supports all optional set operations that this set supports.
    The returned set will throw an IllegalArgumentException on an attempt to insert an element outside its range.
    Equivalent to subSet(fromElement, true, toElement, false).
    This method returns a serializable ImmutableSortedSet.
    The SortedSet.subSet(E, E) documentation states that a subset of a subset throws an IllegalArgumentException if passed a fromElement smaller than an earlier fromElement. However, this method doesn't throw an exception in that situation, but instead keeps the original fromElement. Similarly, this method keeps the original toElement, instead of throwing an exception, if passed a toElement greater than an earlier toElement.

    Description copied from interface: java.util.NavigableSet
    
    Returns a reverse order view of the elements contained in this set. The descending set is backed by this set, so changes to the set are reflected in the descending set, and vice-versa.
