Method transformValues

output/java_guava/1.4.18/Multimaps.java:1176–1180

Returns a view of a multimap where each value is transformed by a function. All other properties of the multimap, such as iteration order, are left intact. For example, the code: {@code Multimap multimap = ImmutableSetMultimap.of("a", 2, "b", -3, "b", -3, "a", 4, "c", 6

(Multimap<K, V1> fromMultimap, final Function<? super V1, V2> function)

  public static <K, V1, V2> Multimap<K, V2> transformValues(Multimap<K, V1> fromMultimap, final Function<? super V1, V2> function) {
    checkNotNull(function);
    EntryTransformer<K, V1, V2> transformer = Maps.asEntryTransformer(function);
    return transformEntries(fromMultimap, transformer);
  }
