Constructor Detail

UnicastRemoteObject

protected UnicastRemoteObject()
                       throws RemoteException

Create and export new remote object without specifying the port value.

Throws:

RemoteException - if the attempt to export the object failed.

UnicastRemoteObject

protected UnicastRemoteObject(int port)
                       throws RemoteException

Create and export the new remote object, making it available at the given port, local host.

Parameters:

port - the port, on that the object should become available. Zero means anonymous port.

Throws:

RemoteException - if the attempt to export the object failed.

UnicastRemoteObject

protected UnicastRemoteObject(int port,
                              RMIClientSocketFactory clientSocketFactory,
                              RMIServerSocketFactory serverSocketFactory)
                       throws RemoteException

Create and export the new remote object, making it available at the given port, using sockets, produced by the specified factories.

Parameters:

port - the port, on that the object should become available. Zero means anonymous port.

clientSocketFactory - the client socket factory

serverSocketFactory - the server socket factory

Throws:

RemoteException - if the attempt to export the object failed.

UnicastRemoteObject

protected UnicastRemoteObject(RemoteRef ref)
                       throws RemoteException

Throws:

RemoteException

Method Detail

clone

public Object clone()
             throws CloneNotSupportedException

Description copied from class: Object

clone creates a shallow clone of this.

Overrides:

clone in class Object

Returns:

a clone of this object.

Throws:

CloneNotSupportedException - if this does not implement the Cloneable interface.

exportObject

public static RemoteStub exportObject(Remote obj)
                               throws RemoteException

Export object, making it available for the remote calls at the anonymous port. This method returns the instance of the abstract class, not an interface. Hence it will not work with the proxy stubs that are supported since jdk 1.5 (such stubs cannot be derived from the RemoteStub). Only use this method if you are sure that the stub class will be accessible.

Parameters:

obj - the object being exported.

Returns:

the remote object stub

Throws:

RemoteException - if the attempt to export the object failed.

exportObject

public static Remote exportObject(Remote obj,
                                  int port)
                           throws RemoteException

Export object, making it available for the remote calls at the specified port. Since jdk 1.5 this method does not longer require the stub class to be present. If such class is not found, the stub is replaced by the dynamically constructed proxy class. No attempt to find and load the stubs is made if the system property java.rmi.server.ignoreStubClasses is set to true (set to reduce the starting time if the stubs are surely not present and exclusively 1.2 RMI is used).

Parameters:

obj - the object being exported.

port - the remote object port

Returns:

the remote object stub

Throws:

RemoteException - if the attempt to export the object failed.

exportObject

public static Remote exportObject(Remote obj,
                                  int port,
                                  RMIClientSocketFactory csf,
                                  RMIServerSocketFactory ssf)
                           throws RemoteException

FIXME

Throws:

RemoteException

unexportObject

public static boolean unexportObject(Remote obj,
                                     boolean force)
                              throws NoSuchObjectException

Throws:

NoSuchObjectException
