output/java_guava/1.4.17/FluentIterable.java:786–788

Returns a map with the contents of this FluentIterable as its values, indexed by keys derived from those values. In other words, each input value produces an entry in the map whose key is the result of applying keyFunction to that value. These entries appear in the same order

(Function<? super E, K> keyFunction)

  public final <K> ImmutableMap<K, E> uniqueIndex(Function<? super E, K> keyFunction) {
    return Maps.uniqueIndex(iterable, keyFunction);
