Class NativeIfNotAssignedIdentityGenerator

java.lang.Object

org.hibernate.id.AbstractPostInsertGenerator

org.hibernate.id.IdentityGenerator

org.openmrs.api.db.hibernate.NativeIfNotAssignedIdentityGenerator

All Implemented Interfaces:

org.hibernate.boot.model.relational.ExportableProducer, org.hibernate.id.BulkInsertionCapableIdentifierGenerator, org.hibernate.id.Configurable, org.hibernate.id.IdentifierGenerator, org.hibernate.id.PostInsertIdentifierGenerator

public class NativeIfNotAssignedIdentityGenerator
extends org.hibernate.id.IdentityGenerator
implements org.hibernate.id.Configurable

native-if-not-assigned

By setting the Hibernate configuration's primary key column to use a "native" implementation, Hibernate ALWAYS generates the entity's id when it is being saved. There is no way to "override" the generated id.

This IdentityGenerator allows a programmer to override the "generated" id, with an "assigned" id at runtime by simply setting the primary key property.
