Interface NaturalIdMultiLoadAccess<T>

All Known Implementing Classes:
NaturalIdMultiLoadAccessStandard

public interface NaturalIdMultiLoadAccess<T>
Loads multiple instances of a given entity type at once, by specifying a list of natural id values. This allows the entities to be fetched from the database in batches.

 List<Book> books =
         session.byMultipleNaturalId(Book.class)
             .withBatchSize(10)
             .multiLoad(isbnList);
 

Composite natural ids may be accommodated by passing a list of maps of type Map<String,Object> to multiLoad(java.lang.Object...). Each map must contain the natural id attribute values keyed by @NaturalId attribute name.

 var compositeNaturalId =
         Map.of(Book_.ISBN, isbn, Book_.PRINTING, printing);
