All Implemented Interfaces:

Map<K,V>

public final class AugmentedMap<K,V>
extends com.google.common.collect.ForwardingMap<K,V>

A map that augments another map with more values. For every key that is not in the base map, a key-value pair will be present in the augmented map, with the value generated by the augmentaiton function.
