org.apache.openjpa.persistence.OpenJPAEntityManager.retrieve()
Immediately load the given object's persistent fields. One might use this action to make sure that an instance's fields are loaded before transitioning it to transient. Note that this action is not recursive. Any related objects that are loaded will not necessarily have their fields loaded.
