public class Util extends Object
| Modifier and Type | Method and Description |
|---|---|
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)
The isLocal method has the same semantics as the
ObjectImpl._is_local
method, except that it can throw a RemoteException.
|
static Class |
loadClass(String className,
String remoteCodebase,
ClassLoader loader)
Returns a class instance for the specified class.
|
static RemoteException |
mapSystemException(SystemException ex)
Maps a SystemException to a RemoteException.
|
static Object |
readAny(InputStream in)
Reads a java.lang.Object as a CORBA any.
|
static void |
registerTarget(Tie tie,
Remote target)
Registers a target for a tie.
|
static void |
unexportObject(Remote target)
Removes the associated tie from an internal table and calls
Tie.deactivate()
to deactivate the object. |
static RemoteException |
wrapException(Throwable orig)
Wraps an exception thrown by an implementation
method.
|
static void |
writeAbstractObject(OutputStream out,
Object obj)
Writes a java.lang.Object as either a value or a CORBA Object.
|
static void |
writeAny(OutputStream out,
Object obj)
Writes any java.lang.Object as a CORBA any.
|
static void |
writeRemoteObject(OutputStream out,
Object obj)
Writes a java.lang.Object as a CORBA Object.
|
public static RemoteException mapSystemException(SystemException ex)
ex - the SystemException to map.public static void writeAny(OutputStream out, Object obj)
out - the stream in which to write the any.obj - the object to write as an any.public static Object readAny(InputStream in)
in - the stream from which to read the any.public static void writeRemoteObject(OutputStream out, Object obj)
obj is
an exported RMI-IIOP server object, the tie is found
and wired to obj, then written to
out.write_Object(org.omg.CORBA.Object).
If obj is a CORBA Object, it is written to
out.write_Object(org.omg.CORBA.Object).out - the stream in which to write the object.obj - the object to write.public static void writeAbstractObject(OutputStream out, Object obj)
obj is a value object or a stub object, it is written to
out.write_abstract_interface(java.lang.Object). If obj
is
an exported
RMI-IIOP server object, the tie is found and wired to obj,
then written to out.write_abstract_interface(java.lang.Object).out - the stream in which to write the object.obj - the object to write.public static void registerTarget(Tie tie, Remote target)
Tie.setTarget(java.rmi.Remote) on the tie object.tie - the tie to register.target - the target for the tie.public static void unexportObject(Remote target) throws NoSuchObjectException
Tie.deactivate()
to deactivate the object.target - the object to unexport.NoSuchObjectExceptionpublic static Tie getTie(Remote target)
public static ValueHandler createValueHandler()
ValueHandler interface.public static String getCodebase(Class clz)
clz - the class to get a codebase for.public static Class loadClass(String className, String remoteCodebase, ClassLoader loader) throws ClassNotFoundException
The spec for this method is the "Java to IDL language mapping", ptc/00-01-06.
In Java SE Platform, this method works as follows:
className - the name of the class.remoteCodebase - a space-separated list of URLs at which
the class might be found. May be null.loader - a ClassLoader that may be used to
load the class if all other methods fail.Class object representing the loaded class.ClassNotFoundException - if class cannot be loaded.public static boolean isLocal(Stub stub) throws RemoteException
stub - the stub to test.RemoteException - The Java to IDL specification does not
specify the conditions that cause a RemoteException to be thrown.public static RemoteException wrapException(Throwable orig)
orig - the exception to wrap.public static Object[] copyObjects(Object[] obj, ORB orb) throws RemoteException
obj - the objects to copy or connect.orb - the ORB.RemoteException - if any object could not be copied or connected.public static Object copyObject(Object obj, ORB orb) throws RemoteException
obj - the object to copy.orb - the ORB.RemoteException - if the object could not be copied or connected. Submit a bug or feature
