@GwtCompatible(serializable=true, emulated=true) public abstract class ImmutableSortedSet<E> extends ImmutableSet<E> implements NavigableSet<E>
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.
See the Guava User Guide article on immutable collections.

that preserves the comparator,
call copyOfSorted(java.util.SortedSet<E>)
instead. This method iterates over elements
at most once.
Note that if s

, 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.
