All Implemented Interfaces:

org.omg.CORBA.Object

public class QoSRepository_impl

extends org.omg.CORBA.LocalObject

The QoSRepository exposes to the Client side of the QPS a suitable interface for setting and getting a RequiredQoS, AgreedQoS and an explicit negotiation. Because the actual QoS information is contained inside the QPS Policy, the QoSRepository, only plays the role of a Focal point for the maintenance of this information.

                                      throws quamj.qps.RepositoryFault

Set the Required QoS for an object.

Returns:

org.omg.CORBA.Object is an object reference to the same object, with some policies set. Clients should continue using this object reference.

get_object

public org.omg.CORBA.Object get_object(java.lang.String client_n_s_id)

This method returns the original reference that is set with policies. To be used during negotiation from within services, when they need to access the policies or the object reference if a current negotiation session, for some reason. The client_n_s_id is the client side unique id of the negotiation QoS session. There is always only one negotiation QoS session per object reference.
