Class _ProxyConsumerStub

The ProxyConsumer interface is intended to be an abstract interface that is inherited by the different varieties of proxy consumers that can be instantiated within a notification channel. It encapsulates the behaviors common to all Notification Service proxy consumers. In particular, the ProxyConsumer 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 consumers to administer a list of associated QoS properties, while the latter inheritance enables all proxy consumers to administer a list of associated filter objects. Locally, the ProxyConsumer interface defines a readonly attribute that should be set upon creation of each proxy consumer instance to indicate the specific type of proxy consumer the instance represents, and a readonly attribute which maintains a reference to the SupplierAdmin object that created it. In addition, the ProxyConsumer interface defines an operation that returns the list of event types a given proxy consumer instance is configured to forward, and an operation which can be queried to determine which message level QoS properties can be set on a per-event basis.
