Class SafeTreeMap<K,V>

java.lang.Object

com.google.common.collect.testing.SafeTreeMap<K,V>

All Implemented Interfaces:

Serializable, Map<K,V>, NavigableMap<K,V>, SequencedMap<K,V>, SortedMap<K,V>

@GwtIncompatible
public final class SafeTreeMap<K,V>
extends Object
implements Serializable, NavigableMap<K,V>

A wrapper around TreeMap that aggressively checks to see if keys are mutually comparable. This implementation passes the navigable map test suites.
