Class RepositoryIterator

java.lang.Object
  atg.repository.search.indexing.config.RepositoryIterator

public class RepositoryIterator
extends java.lang.Object

An instance of this class can be configured to act as an iterator through a repository for a given item descriptor.
It will load repository items in batches to avoid performance problems with large repository sets.
It is also possible to start iterating from a specific repository id.
