Method transformEntries

output/java_guava/1.4.17/Multimaps.java:1239–1241

Returns a view of a multimap whose values are derived from the original multimap's entries. In contrast to #transformValues, this method's entry-transformation logic may depend on the key as well as the value. All other properties of the transformed multimap, such as iteration order, are
