public abstract class ProxySupplierPOA
extends org.omg.PortableServer.Servant
implements ProxySupplierOperations, org.omg.CORBA.portable.InvokeHandler

The ProxySupplier interface is intended to be an abstract interface that is inherited by the different varieties of proxy suppliers that can be instantiated within a notification channel. It encapsulates the behaviors common to all Notification Service proxy suppliers. In particular, the ProxySupplier interface inherits the QoSAdmin interface defined within the CosNotification module, and the FilterAdmin interface defined within the CosNotifyFilter module. The former inheritance enables all proxy suppliers to administer a list of associated QoS properties, while the latter inheritance enables all proxy suppliers to administer a list of associated filter objects. Locally, the ProxySupplier interface defines a readonly attribute that should be set upon creation of each proxy supplier instance to indicate the specific type of proxy supplier the instance represents, and a readonly attribute which maintains a reference to the ConsumerAdmin object that created it. In addition, the ProxySupplier interface defines attributes that associate with each proxy supplier two mapping filter objects, one for priority and one for lifetime. As described in section 2.3.1, these mapping filter objects enable proxy suppliers to be configured to alter the way they treat events with respect to their priority and lifetime based on the type and contents of each individual event. Lastly, the ProxySupplier interface defines an operation that returns the list of event types that a given proxy supplier could potentially forward to its associated consumer, and an operation which can be queried to determine which message level QoS properties can be set on a per-event basis.
