Class CustomBatchLoaderFactory

java.lang.Object
org.hibernate.loader.ast.internal.StandardBatchLoaderFactory
ch.tocco.nice2.persist.core.impl.hibernate.persister.CustomBatchLoaderFactory
All Implemented Interfaces:
Serializable, org.hibernate.loader.ast.spi.BatchLoaderFactory, org.hibernate.service.Service
public class CustomBatchLoaderFactory extends org.hibernate.loader.ast.internal.StandardBatchLoaderFactory
Wrap StandardBatchLoaderFactory to lazy load LazyCollectionLoader. The CollectionLoader are used in AbstractCollectionPersister (superclass of ExtendedBasicCollectionPersister and ExtendedOneToManyPersister). Overriding createCollectionLoader is no longer possible, so do it here. As we have a custom collection initialization mechanism (ExtendedInitializeCollectionEventListener), the initializers of the superclass are probably never used. Therefore we don't initialize them until necessary, as they take up a lot of memory.
