Interface UtilDelegate

public interface UtilDelegate

Supports delegation for method implementations in Util. The delegate is a singleton instance of a class that implements this interface and provides a replacement implementation for all the methods of javax.rmi.CORBA.Util. Delegation is enabled by providing the delegate's class name as the value of the javax.rmi.CORBA.UtilClass system property.

Parameters:

ex - the SystemException to map.

Returns:

the mapped exception.

writeAny

void writeAny(OutputStream out,
              Object obj)

Delegation call for Util.writeAny(org.omg.CORBA.portable.OutputStream, java.lang.Object).

Parameters:

out - the stream in which to write the any.

obj - the object to write as an any.

readAny

Object readAny(InputStream in)

Delegation call for Util.readAny(org.omg.CORBA.portable.InputStream).

Parameters:

in - the stream from which to read the any.

Returns:

the object read from the stream.

writeRemoteObject

                       Object obj)

Delegation call for Util.writeRemoteObject(org.omg.CORBA.portable.OutputStream, java.lang.Object).

Parameters:

out - the stream in which to write the object.

writeAbstractObject

void writeAbstractObject(OutputStream out,
                         Object obj)

Delegation call for Util.writeAbstractObject(org.omg.CORBA.portable.OutputStream, java.lang.Object).

Parameters:

out - the stream in which to write the object.

obj - the object to write.

registerTarget

void registerTarget(Tie tie,
                    Remote target)

Delegation call for Util.registerTarget(javax.rmi.CORBA.Tie, java.rmi.Remote).

Parameters:

tie - tie to register

target - target for the tie

unexportObject

void unexportObject(Remote target)
             throws NoSuchObjectException

Delegation call for Util.unexportObject(java.rmi.Remote).

Parameters:

target - the object to unexport

Throws:

NoSuchObjectException - if the target object does not exist

getTie

Tie getTie(Remote target)

Delegation call for Util.getTie(java.rmi.Remote).

Parameters:

target - the object to get the tie for

Returns:

the tie or null if no tie is registered for the given target.

createValueHandler

ValueHandler createValueHandler()

Delegation call for Util.createValueHandler().

Returns:

a class which implements the ValueHandler interface.

getCodebase

String getCodebase(Class clz)

Delegation call for Util.getCodebase(java.lang.Class).

Parameters:

clz - the class to get a codebase for.

Returns:

a space-separated list of URLs, or null.

loadClass

Class loadClass(String className,
                String remoteCodebase,
                ClassLoader loader)
         throws ClassNotFoundException

Delegation call for Util.loadClass(java.lang.String, java.lang.String, java.lang.ClassLoader).

Parameters:

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.

Returns:

the Class object representing the loaded class.

Throws:

ClassNotFoundException - if class cannot be loaded.

isLocal

boolean isLocal(Stub stub)
         throws RemoteException

Delegation call for Util.isLocal(javax.rmi.CORBA.Stub).

Parameters:

stub - the stub to test.

Returns:

The is_local() method returns true if the servant incarnating the object is located in the same process as the stub and they both share the same ORB instance. The is_local() method returns false otherwise. The default behaviour of is_local() is to return false.

Throws:

RemoteException - The Java to IDL specification does not specify the conditions that cause a RemoteException to be thrown.
