java.lang.Object | +--javax.rmi.CORBA.Util
Provides utility methods that can be used by stubs and ties to perform common operations.
Method Summary | |
static Object |
copyObject(Object obj,
ORB orb)
Copies or connects an object. |
static Object[] |
copyObjects(Object[] obj,
ORB orb)
Copies or connects an array of objects. |
static ValueHandler |
createValueHandler()
Returns a singleton instance of a class that implements the ValueHandler interface. |
static String |
getCodebase(Class clz)
Returns the codebase, if any, for the given class. |
static Tie |
getTie(Remote target)
Returns the tie (if any) for a given target object. |
static boolean |
isLocal(Stub stub)

static void |
registerTarget(Tie tie,
Remote target)
