public class PersistentFieldDirectImpl
extends PersistentFieldBase

This PersistentField implementation is the high-speed version of the access strategies.
It does not cooperate with an AccessController, but accesses the fields directly. This implementation persistent attributes don't need getters and setters and don't have to be declared public or protected. Only the the metadata field names have to match the class fields.
