All Implemented Interfaces:
FieldManager
public class PersistFieldManager extends AbstractFieldManager
Field manager that persists all unpersisted PC objects referenced from the source object. If any collection/map fields are not currently using SCO wrappers they will be converted to do so. Effectively provides "persistence-by-reachability" (at insert/update).
