Field Detail

AGGREGATED_COMPOSITEback to summary
public static final EntityIdentifierNature AGGREGATED_COMPOSITE

Composite identifier mapped to a single entity attribute by means of an actual component class used to aggregate the tuple values. Equivalent of:

  • a <composite-id/> mapping naming a single identifier attribute via the name XML-attribute
  • an @EmbeddedId annotation

NON_AGGREGATED_COMPOSITEback to summary
public static final EntityIdentifierNature NON_AGGREGATED_COMPOSITE

What Hibernate used to term an "embedded composite identifier", which is not to be confused with the JPA term embedded. Resolved as a tuple of basic type values and mapped over multiple singular attributes. Specifically a composite identifier where there is no single attribute representing the composite value. Equivalent of:

  • a <composite-id/> mapping without a specified name XML-attribute (which would name the single identifier attribute
  • multiple @Id annotations
NOTE : May or may not have a related "lookup identifier class" as indicated by a @IdClass annotation.
