I would like to run a query for a list of entities but instead of receiving a List<> of entities I would like it to process the entities one at a time in a callback of some sort. The query will return hundreds of thousands of entities and I just need to read some values and add them to various counters before disposing of the item. In the past I have used a Spring JDBC template to do this but want to make use of existing Hibernate code. Is there any kind of row/entity callback in hibernate?

[EDIT]
I've just spotted the iterate() function for the Query.
