All Implemented Interfaces:

Serializable, Iterable<E>, Collection<E>, NavigableSet<E>, Set<E>, SortedSet<E>
```
@GwtIncompatible
public final class SafeTreeSet<E>
extends Object
implements Serializable, NavigableSet<E>
```
A wrapper around TreeSet that aggressively checks to see if elements are mutually comparable. This implementation passes the navigable set test suites.
