ANavigableSet
whose contents will never change, with many other important properties detailed atImmutableCollection
.Warning: as with any sorted collection, you are strongly advised not to use a
Comparator
orComparable
type whose comparison behavior is inconsistent with equals. That is,a.compareTo(b)
orcomparator.compare(a, b)
should equal zero if and only ifa.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.

This method is not type-safe, as it may be called on elements that are not mutually comparable.
