Method filterFiltered

output/java_guava/1.4.19/Multimaps.java:2138–2141

Support removal operations when filtering a filtered multimap. Since a filtered multimap has iterators that don't support remove, passing one to the FilteredEntryMultimap constructor would lead to a multimap whose removal operations would fail. This method combines the predicates to avoid that probl
