Examples of org.hibernate.Session.saveOrUpdate()

org.hibernate.Session.saveOrUpdate()
Either {@link #save(Object)} or {@link #update(Object)} the giveninstance, depending upon resolution of the unsaved-value checks (see the manual for discussion of unsaved-value checking).
This operation cascades to associated instances if the association is mapped with cascade="save-update". @see Session#save(java.lang.Object) @see Session#update(Object object) @param object a transient or detached instance containing new or updated state @throws HibernateException
