All Implemented Interfaces:

InvokeHandler, NamingContextExtOperations, NamingContextOperations

public abstract class NamingContextExtPOA

extends Servant

implements NamingContextExtOperations, InvokeHandler

NamingContextExt is the extension of NamingContext which contains a set of name bindings in which each name is unique and is part of Interoperable Naming Service. Different names can be bound to an object in the same or different contexts at the same time. Using NamingContextExt, you can use URL-based names to bind and resolve.

See CORBA COS Naming Specification.

Method Detail

_invoke

public OutputStream _invoke(String $method,
                            InputStream in,
                            ResponseHandler $rh)

Description copied from interface: InvokeHandler

Invoked by the ORB to dispatch a request to the servant. ORB passes the method name, an InputStream containing the marshalled arguments, and a ResponseHandler which the servant uses to construct a proper reply. Only CORBA SystemException may be thrown by this method. The method must return an OutputStream created by the ResponseHandler which contains the marshalled reply. A servant must not retain a reference to the ResponseHandler beyond the lifetime of a method invocation. Servant behaviour is defined as follows:

1. Determine correct method, and unmarshal parameters from InputStream.

2. Invoke method implementation.

3. If no user exception, create a normal reply using ResponseHandler.

4. If user exception occurred, create exception reply using ResponseHandler.

5. Marshal reply into OutputStream returned by ResponseHandler.

6. Return OutputStream to ORB.

Specified by:

_invoke in interface InvokeHandler

Parameters:

$method - The method name.

in - The InputStream containing the marshalled arguments.

$rh - The ResponseHandler which the servant uses to construct a proper reply

Returns:

The OutputStream created by the ResponseHandler which contains the marshalled reply

_all_interfaces

public String[] _all_interfaces(POA poa,
                                byte[] objectId)

Description copied from class: Servant

Used by the ORB to obtain complete type information from the servant.

Specified by:
