org.omg.CosNaming
Class BindingIteratorPOA

java.lang.Object
  org.omg.PortableServer.Servant
      org.omg.CosNaming.BindingIteratorPOA

All Implemented Interfaces:

InvokeHandler, BindingIteratorOperations

---

public abstract class BindingIteratorPOA
extends Servant
implements BindingIteratorOperations, InvokeHandler

The BindingIterator interface allows a client to iterate through the bindings using the next_one or next_n operations. The bindings iterator is obtained by using the list method on the NamingContext.

See Also:

NamingContextOperations.list(int, org.omg.CosNaming.BindingListHolder, org.omg.CosNaming.BindingIteratorHolder)

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:

_all_interfaces in class Servant

Parameters:

poa - POA with which the servant is associated.

objectId - is the id corresponding to the object associated with this servant.

Returns:

list of type information for the object.
