Method Detail

• mapSystemException

  public static RemoteException mapSystemException(SystemException ex)

  Maps a SystemException to a RemoteException.

  Parameters:

  ex - the SystemException to map.

  Returns:

  the mapped exception.

• writeAny

  public static void writeAny(OutputStream out,Object obj)

  Writes any java.lang.Object as a CORBA any.

  Parameters:

  out - the stream in which to write the any.

  obj - the object to write as an any.

• readAny

  public static Object readAny(InputStream in)

  Reads a java.lang.Object as a CORBA any.

  Parameters:

  in - the stream from which to read the any.

  Returns:

  the object read from the stream.

• writeRemoteObject

  public static void writeRemoteObject(OutputStream out,Object obj)

  Writes a java.lang.Object as a CORBA Object. Ifobj is an exported RMI-IIOP server object, the tie is found and wired toobj, then written toout.write_Object(org.omg.CORBA.Object). Ifobj is a CORBA Object, it is written toout.write_Object(org.omg.CORBA.Object).

  Parameters:

  out - the stream in which to write the object.

  obj - the object to write.

• writeAbstractObject

  public static void writeAbstractObject(OutputStream out,Object obj)

  Writes a java.lang.Object as either a value or a CORBA Object. Ifobj is a value object or a stub object, it is written toout.write_abstract_interface(java.lang.Object). Ifobj is an exported RMI-IIOP server object, the tie is found and wired toobj, then written toout.write_abstract_interface(java.lang.Object).

  Parameters:

  out - the stream in which to write the object.

  obj - the object to write.

• registerTarget

  public static void registerTarget(Tie tie,Remote target)

  Registers a target for a tie. Adds the tie to an internal table and callsTie.setTarget(java.rmi.Remote) on the tie object.

  Parameters:

  tie - the tie to register.

  target - the target for the tie.

• unexportObject

  public static void unexportObject(Remote target)                           throwsNoSuchObjectException

  Removes the associated tie from an internal table and callsTie.deactivate() to deactivate the object.

  Parameters:

  target - the object to unexport.

  Throws:

  NoSuchObjectException

• getTie

  public static Tie getTie(Remote target)

  Returns the tie (if any) for a given target object.

  Returns:

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

• createValueHandler

  public static ValueHandler createValueHandler()

  Returns a singleton instance of a class that implements theValueHandler interface.

  Returns:

  a class which implements the ValueHandler interface.

• getCodebase

  public static String getCodebase(Class clz)

  Returns the codebase, if any, for the given class.

  Parameters:

  clz - the class to get a codebase for.

  Returns:

  a space-separated list of URLs, or null.

• loadClass

  public static Class loadClass(String className,String remoteCodebase,ClassLoader loader)                       throwsClassNotFoundException

  Returns a class instance for the specified class.

  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:

  • Find the first non-nullClassLoader on the call stack and attempt to load the class using thisClassLoader.
  • If the first step fails, and ifremoteCodebase is non-null anduseCodebaseOnly is false, then calljava.rmi.server.RMIClassLoader.loadClass(remoteCodebase, className).
  • IfremoteCodebase is null oruseCodebaseOnly is true, then calljava.rmi.server.RMIClassLoader.loadClass(className).
  • If a class was not successfully loaded by step 1, 2, or 3, andloader is non-null, then callloader.loadClass(className).
  • If a class was successfully loaded by step 1, 2, 3, or 4, then return the loaded class, else throwClassNotFoundException.

  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 - aClassLoader that may be used to load the class if all other methods fail.

  Returns:

  theClass object representing the loaded class.

  Throws:

  ClassNotFoundException - if class cannot be loaded.

• isLocal

  public static boolean isLocal(Stub stub)                       throwsRemoteException

  TheisLocal method has the same semantics as theObjectImpl._is_local method, except that it can throw aRemoteException. The_is_local() method is provided so that stubs may determine if a particular object is implemented by a local servant and hence local invocation APIs may be used.

  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 behavior of_is_local() is to return false.

  Throws:

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

• wrapException

  public static RemoteException wrapException(Throwable orig)

  Wraps an exception thrown by an implementation method. It returns the corresponding client-side exception.

  Parameters:

  orig - the exception to wrap.

  Returns:

  the wrapped exception.

• copyObjects

  public static Object[] copyObjects(Object[] obj,ORB orb)                            throwsRemoteException

  Copies or connects an array of objects. Used by local stubs to copy any number of actual parameters, preserving sharing across parameters as necessary to support RMI semantics.

  Parameters:

  obj - the objects to copy or connect.

  orb - the ORB.

  Returns:

  the copied or connected objects.

  Throws:

  RemoteException - if any object could not be copied or connected.

• copyObject

  public static Object copyObject(Object obj,ORB orb)                         throwsRemoteException

  Copies or connects an object. Used by local stubs to copy an actual parameter, result object, or exception.

  Parameters:

  obj - the object to copy.

  orb - the ORB.

  Returns:

  the copy or connected object.

  Throws:

  RemoteException - if the object could not be copied or connected.
