Does the Hibernate API support object result sets in the form of a collection

Does the Hibernate API support object result sets in the form of a collection other than a List?

For example, I have process that runs hundreds of thousands of iterations in order to create some data for a client. This process uses records from a Value table (for example) in order to create this output for each iteration.

With a List I would have to iterate through the entire list in order to find a certain value, which is expensive. I’d like to be able to return a TreeMap and specify a key programmatically so I can search the collection for the specific value I need. Can Hibernate do this for me?

  1. I assume you are referring to the Query.list() method. If so: no, there is no way to return top-level results other than a List. If you are receiving too many results, why not issue a more constrained query to the database? If the query is difficult to constrain, you can populate your own Map with the contents of Hibernate’s List and then throw away the list.
