cz.encircled.joiner.feature.PostQueryLazyFetchBlockerFeature

All Implemented Interfaces:

QueryFeature

public class PostQueryLazyFetchBlockerFeature
extends Object
implements QueryFeature

Use this query feature to prevent uninitialized lazy attributes from being fetched when accessed. Uninitialized attributes will be initialized with an empty collection or null for singular associations. This works only with Hibernate stateless sessions, which can be enabled at the query level or globally using JoinerProperties.setUseStatelessSessions(boolean))
