public EntityBatchLoaderArrayParam(int domainBatchSize, EntityMappingType entityDescriptor, SessionFactoryImplementor sessionFactory)

Deprecated

as a consequence of SessionFactoryImplementor being deprecated. See corresponding docs for further information.

Instantiates the loader

Implementation Note

We delay initializing the internal SQL AST state until first use. Creating the SQL AST internally relies on the entity's EntityIdentifierMapping. However, we do create the static batch-loader for the entity in the persister constructor and EntityIdentifierMapping is not available at that time. On first use, we know we have it available

Parameters
domainBatchSize:int

The number of domain model parts (up to)
