Interface ResultSetProcessor

All Known Implementing Classes:

ResultSetProcessorImpl

public interface ResultSetProcessor

Contract for processing JDBC ResultSets. Separated because ResultSets can be chained and we'd really like to reuse this logic across all result sets.

todo : investigate having this work with non-JDBC results; maybe just typed as Object? or a special Result contract?

List extractResults(LoadPlanAdvisor loadPlanAdvisor,
                  ResultSet resultSet,
                  SessionImplementor session,
                  QueryParameters queryParameters,

                  List<AfterLoadAction> afterLoadActions)
                    throws SQLException

Process an entire ResultSet, performing all extractions. Semi-copy of Loader.doQuery(org.hibernate.engine.spi.SessionImplementor, org.hibernate.engine.spi.QueryParameters, boolean, org.hibernate.transform.ResultTransformer), with focus on just the ResultSet processing bit.

Parameters:

loadPlanAdvisor - A dynamic advisor on the load plan.

resultSet - The result set being processed.

session - The originating session

queryParameters - The "parameters" used to build the query

returnProxies - Can proxies be returned (not the same as can they be created!)

forcedResultTransformer - My old "friend" ResultTransformer...

afterLoadActions - Actions to be performed after loading an entity.

Returns:

The extracted results list.

Throws:

SQLException - Indicates a problem access the JDBC ResultSet
