类 LoadQueryJoinAndFetchProcessor

java.lang.Object

org.hibernate.loader.plan.exec.internal.LoadQueryJoinAndFetchProcessor

public class LoadQueryJoinAndFetchProcessor
extends Object

Helper for implementors of entity and collection based query building based on LoadPlans providing common functionality, especially in regards to handling QuerySpace Joins and Fetches.

Exposes 2 main methods:

1. processQuerySpaceJoins(QuerySpace, SelectStatementBuilder)
2. processFetches(FetchSource, SelectStatementBuilder, org.hibernate.loader.plan.exec.process.spi.ReaderCollector)li>
