Examples of org.hibernate.Session.evict()

org.hibernate.Session.evict()
Remove this instance from the session cache. Changes to the instance will not be synchronized with the database. This operation cascades to associated instances if the association is mapped with cascade="evict". @param object a persistent instance @throws HibernateException
