Method Detail

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Description copied from class: java.lang.Object

This method may be called to create a new copy of the Object. The typical behavior is as follows:

• o == o.clone() is false
• o.getClass() == o.clone().getClass() is true
• o.equals(o) is true

However, these are not strict requirements, and may be violated if necessary. Of the three requirements, the last is the most commonly violated, particularly if the subclass does not override Object.equals(Object)>Object.equals(Object) 55 .

If the Object you call clone() on does not implement java.lang.Cloneable (which is a placeholder interface), then a CloneNotSupportedException is thrown. Notice that Object does not implement Cloneable; this method exists as a convenience for subclasses that do.

Object's implementation of clone allocates space for the new Object using the correct class, without calling any constructors, and then fills in all of the new field values with the old field values. Thus, it is a shallow copy. However, subclasses are permitted to make a deep copy.

All array types implement Cloneable, and override this method as follows (it should never fail):

 public Object clone()
 {
   try
     {
       super.clone();
     }
   catch (CloneNotSupportedException e)
     {
       throw new InternalError(e.getMessage());
     }
 }

exportObject

public static RemoteStub exportObject(java.rmi.Remote obj)
                               throws java.rmi.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.

---

exportObject

public static java.rmi.Remote exportObject(java.rmi.Remote obj,
                                           int port)
                                    throws java.rmi.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).

---

exportObject

static java.rmi.Remote exportObject(java.rmi.Remote obj,
                                    int port,
                                    RMIServerSocketFactory serverSocketFactory)
                             throws java.rmi.RemoteException

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