A BiMap<K,V> whose contents will never change, with many other important properties detailed at ImmutableCollection<E>.
A RangeMap<K,V> whose contents will never change, with many other important properties detailed at ImmutableCollection<E>.
A Multimap that can hold duplicate key-value pairs and that maintains the insertion ordering of values for a given key. See the Multimap<K,V> documentation for information common to all multimaps. The #get, #removeAll, and #replaceValues methods each return a List of values. Though the method signature doesn't say so explicitly, the map returned by #asMap has List values. See the Guava User Guide article on Multimap.
A concurrent map which forwards all its method calls to another concurrent map. Subclasses should override one or more methods to modify the behavior of the backing map as desired per the decorator pattern. default method warning: This class forwards calls to only some default methods. Specifically, it forwards calls only for methods that existed before default methods were introduced. For newer methods, like forEach, it inherits their default implementations. When those implementations invoke methods, they invoke methods on the ForwardingConcurrentMap.
