> The usage of *MultiCollector* sometimes is very convenient along with
> {*}CollectorManager{*}s instances (as an alternative to
> {*}MultiCollectorManager{*}), for example:
> {code:java}
> class SomeCollectorManager implements CollectorManager<Collector, ?> {
> @Override
> public Collector newCollector() throws IOException {
> return MultiCollector.wrap(new Collector1(), new Collector2(), ...);
> }
> @Override
> public List<Integer> reduce(Collection<Collector> collectors) throws
> IOException {
> return ...;
> }
> }{code}
> Unfortunately, the *reduce()* phase is lacking the access to
> *MultiCollector::getCollectors* method, since it is package protected at the
> moment. Making *MultiCollector::getCollectors* public would make it
> convenient to use *MultiCollector +* *CollectorManager* and implement the
> reduce phase by accessing individual collectors.
