All Implemented Interfaces:

FieldConsumer, FieldManager, FieldSupplier

public class PersistFieldManager
extends AbstractFieldManager

Field manager that perists 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).
