Class org.omg.CORBA.portable.ObjectImpl

java.lang.Object
  |
  +--org.omg.CORBA.portable.ObjectImpl

Direct Known Subclasses:

DynamicImplementation

public abstract class ObjectImpl

extends Object

implements Object

The ObjectImpl class provides default implementations of the org.omg.CORBA.Object methods. All method implementations are forwarded to a Delegate object stored in the ObjectImpl instance. ObjectImpl is the common base class for all stub classes. ObjectImpl allows for portable stubs because the Delegate can be implemented by a different vendor-specific ORB.

_is_local

public boolean _is_local()

_servant_preinvoke

public ServantObject _servant_preinvoke(String operation,
                                        Class expectedType)

_servant_postinvoke

public void _servant_postinvoke(ServantObject servant)

_request

public OutputStream _request(String operation,
                             boolean responseExpected)

_request is called by a stub to obtain an OutputStream for marshaling arguments. The stub must supply the operation name, and indicate if a response is expected (i.e is this a oneway call).

_invoke

public InputStream _invoke(OutputStream output)
                    throws ApplicationException,
                           SystemException

_invoke is called to invoke an operation. The stub provides an OutputStream that was previously returned by a _request() call. _invoke returns an InputStream which contains the marshaled reply. If an exception occurs, _invoke may throw an ApplicationException object which contains an InputStream from which the user exception state may be unmarshaled.

_releaseReply

public void _releaseReply(InputStream input)

_releaseReply may optionally be called by a stub to release a reply stream back to the ORB when the unmarshaling has completed. The stub passes the InputStream returned by _invoke() or ApplicationException.getInputStream(). A null value may also be passed to _releaseReply, in which case the method is a noop.
