Class BatchingEntityLoaderBuilder

java.lang.Object

org.hibernate.loader.entity.BatchingEntityLoaderBuilder

Direct Known Subclasses:

AbstractBatchingEntityLoaderBuilder

public abstract class BatchingEntityLoaderBuilder
extends java.lang.Object

The contract for building UniqueEntityLoader capable of performing batch-fetch loading. Intention is to build these instances, by first calling the static getBuilder(org.hibernate.engine.spi.SessionFactoryImplementor), and then calling the appropriate buildLoader(org.hibernate.persister.entity.OuterJoinLoadable, int, org.hibernate.LockMode, org.hibernate.engine.spi.SessionFactoryImplementor, org.hibernate.engine.spi.LoadQueryInfluencers) method.

batchSize - The maximum number of ids to batch-fetch at once

lockMode - The lock mode

factory - The SessionFactory

influencers - Any influencers that should affect the built query

Returns:

The loader.
