public abstract class DbObjectRemoteDelegateImpl<T extends DbObject>
extends RemoteDelegateImpl<T>
implements DbObjectRemoteDelegate

Base class for the remote delegate of DbObject.
All other subclasses of DbObject should extend DbObjectRemoteDelegateImpl to reflect the class hierarchy below DbObject.

DbObjectRemoteDelegateImpl

public DbObjectRemoteDelegateImpl(RemoteDbSessionImpl session,
                                  Class<T> clazz,
                                  int port,

                           throws RemoteException

Creates delegate.

Parameters:

session - is the RMI session

clazz - is the class the delegate provides service for

port - the port number on which the remote object receives calls, 0 = system default

csf - the client-side socket factory for making calls to the remote object, null = system default

ssf - the server-side socket factory for receiving remote calls, null = system default

Throws:

RemoteException

DbObjectRemoteDelegateImpl

Creates a delegate on the session socket.

Parameters:

session - is the RMI session

clazz - is the subclass of DbObject

Throws:

RemoteException
