protected RemoteObject() 
{
        ref = null;
}

Creates a remote object.

 protected RemoteObject(RemoteRef newref) 
{
        ref = newref;
}

Creates a remote object, initialized with the specified remote reference.

Parameters:

newref - remote reference

 public boolean equals(Object obj) 
{
        if (obj instanceof RemoteObject) {
            if (ref == null) {
                return obj == this;
            } else {
                return ref.remoteEquals(((RemoteObject)obj).ref);
            }
        } else if (obj != null) {
            /*
             * Fix for 4099660: if object is not an instance of RemoteObject,

             * remote object implementation class that does not extend
             * RemoteObject wishes to support equality with its stub objects.

            return obj.equals(this);
        } else {
            return false;
        }
}

Compares two remote objects for equality. Returns a boolean that indicates whether this remote object is equivalent to the specified Object. This method is used when a remote object is stored in a hashtable. If the specified Object is not itself an instance of RemoteObject, then this method delegates by returning the result of invoking the equals method of its parameter with this remote object as the argument.

 public RemoteRef getRef() 
{
        return ref;
}

Returns the remote reference for the remote object.

Note: The object returned from this method may be an instance of an implementation-specific class. The RemoteObject class ensures serialization portability of its instances' remote references through the behavior of its custom writeObject and readObject methods. An instance of RemoteRef should not be serialized outside of its RemoteObject wrapper instance or the result may be unportable.

 public int hashCode() 
{
        return (ref == null) ? super.hashCode() : ref.remoteHashCode();
}

Returns a hashcode for a remote object. Two remote object stubs that refer to the same remote object will have the same hash code (in order to support remote objects as keys in hash tables).

 public String toString() 
{
        String classname = Util.getUnqualifiedName(getClass());
        return (ref == null) ? classname :
            classname + "[" + ref.remoteToString() + "]";
}

Returns a String that represents the value of this remote object.

 public static Remote toStub(Remote obj) throws NoSuchObjectException 
{
        if (obj instanceof RemoteStub ||
            (obj != null &&
             Proxy.isProxyClass(obj.getClass()) &&
             Proxy.getInvocationHandler(obj) instanceof
             RemoteObjectInvocationHandler))
        {
            return obj;
        } else {
            return sun.rmi.transport.ObjectTable.getStub(obj);
        }
}

Returns the stub for the remote object obj passed as a parameter. This operation is only valid after the object has been exported.
