- All Implemented Interfaces:
FieldManager
public class ReachabilityFieldManager extends AbstractFieldManager
Field manager that runs reachability on all PC objects referenced from the source object. Whenever a PC object is encountered it recurses to that object, and so on. Provides the basis for the JDO feature "persistence-by-reachability-at-commit".
