public interface NonAggregatedIdentifierMapping
extends CompositeIdentifierMapping, EmbeddableValuedFetchable, FetchOptions, VirtualModelPart

A "non-aggregated" composite identifier, which means that the entity itself does not define a singular representation of its identifier like an aggregated mapping does. An IdClass can be used to provide a simple, singular representation of the identifier for easier reference in API calls. JPA requires using an IdClass when mapping such identifiers. Hibernate supports mapping such identifiers with or without the IdClass; without, the entity itself is used as the identifier.

getFetchableKey

default int getFetchableKey()

Description copied from interface: Fetchable

The key that identifies this Fetchable within a FetchableContainer. If this Fetchable is part of FetchableContainer.visitFetchables(IndexedConsumer, EntityMappingType), the values is guaranteed to be between 0 (inclusive) and FetchableContainer.getNumberOfFetchableKeys() (exclusive). Other Fetchable objects may have a special negative value.

The main intent of this key is to index e.g. Fetch objects in an array.
