 org.apache.catalina.cluster.session.DeltaSession
| DeltaSession | | public class DeltaSession implements HttpSession,Session,Serializable,ClusterSession(Code) | | Similar to the StandardSession, this code is identical, but for update
and some small issues, simply copied in the first release.
This session will keep track of deltas during a request.
IMPLEMENTATION NOTE: An instance of this class represents both the
internal (Session) and application level (HttpSession) view of the session.
However, because the class itself is not declared public, Java logic outside
of the org.apache.catalina.session package cannot cast an
HttpSession view of this instance back to a Session view.
IMPLEMENTATION NOTE: If you add fields to this class, you must
make sure that you carry them over in the read/writeObject methods so
that this class is properly serialized.
