If you're wondering why DelegatingCollector as opposed to SimpleCollector or other options, there's not a great answer - DelegatingCollector was needed in some earlier revision when things were postfilter based. I've changed it to use SimpleCollector; hopefully that addresses your concern. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
