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?

Method Detail

toOnDemandForm

@Deprecated
ScrollableResultSetProcessor toOnDemandForm()

Deprecated. Going away!

Make this go somewhere else. These aren't really linked this way anymore. ScrollableResultSetProcessor is not tied in yet, so not sure yet exactly how that will play out.

extractResults

List extractResults(ResultSet resultSet,
                    SessionImplementor session,
                    QueryParameters queryParameters,
                    NamedParameterContext namedParameterContext,
                    boolean returnProxies,
                    boolean readOnly,
                    ResultTransformer forcedResultTransformer,
                    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:

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
