public class PurgeProducer
extends atg.repository.PagedQueryIteratorFactory

Purge producer is obtaining candidate items for purging and pass them to purge executor for actual purge work. It also keeps track of purge results and update corresponding purge progress item. We are checking purge progress repository to allow only a single purge to be executed at a time.
