                  org.tentackle.db.rmi.DbOperationRemoteDelegateImpl<T>

Type Parameters:

T - the database operation class

All Implemented Interfaces:

Serializable, Remote, DbOperationRemoteDelegate, RemoteDelegate

Direct Known Subclasses:

AppDbOperationRemoteDelegateImpl

public abstract class DbOperationRemoteDelegateImpl<T extends DbOperation>
extends RemoteDelegateImpl<T>
implements DbOperationRemoteDelegate

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

DbOperationRemoteDelegateImpl

public DbOperationRemoteDelegateImpl(RemoteDbSessionImpl session,
                                     Class<T> clazz,
                                     int port,
                                     RMIClientSocketFactory csf,
                                     RMIServerSocketFactory ssf)
                              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

DbOperationRemoteDelegateImpl

public DbOperationRemoteDelegateImpl(RemoteDbSessionImpl session,
                                     Class<T> clazz)
                              throws RemoteException

Creates a delegate on the session socket.

Parameters:

session - is the RMI session

clazz - is the subclass of DbOperation

Throws:

RemoteException

DbOperationRemoteDelegateImpl

public DbOperationRemoteDelegateImpl(RemoteDbSessionImpl session,
                                     Class<T> clazz,
                                     int socketConfig)
                              throws RemoteException

Creates a delegate on a non-default session socket.

Parameters:

session - is the RMI session

clazz - is the subclass of DbOperation

socketConfig - is of RemoteDbSessionImpl.SOCKETCONFIG_...

Throws:

RemoteException

Method Detail

setup

protected void setup()
              throws RemoteException

Instantiates a singe object and connect it to the db. (if class is not abstract). The object is used for all methods not returning a new object and thus minimizes object construction.

Throws:

RemoteException

newObject

protected T newObject()
                                   throws RemoteException

Creates a new instance of the required class for methods that return a new object.

Returns:

the new object

Throws:

RemoteException
