public abstract class ProxyPullSupplierPOA
extends org.omg.PortableServer.Servant
implements ProxyPullSupplierOperations, org.omg.CORBA.portable.InvokeHandler

The ProxyPullSupplier interface supports connections to the channel by consumers who will pull events from the channel as untyped Anys. Through inheritance of the ProxySupplier interface, the ProxyPullSupplier interface supports administration of various QoS properties, administration of a list of associated filter objects, mapping filters for event priority and lifetime, and a readonly attribute containing the reference of the ConsumerAdmin object which created it. In addition, this inheritance implies that a ProxyPullSupplier instance supports an operation which will return the list of event types which the proxy supplier will potentially by supplying, and an operation which can return information about the instance?s ability to accept a per-event QoS request. The ProxyPullSupplier interface also inherits from the PullSupplier interface defined within the CosNotifyComm module. This interface supports the pull and try_pull operations which the consumer connected to a ProxyPullSupplier instance will invoke to receive an event from the channel in the form of an Any, and the operation required to disconnect the ProxyPullSupplier from its associated consumer. In addition, since the inherited PullSupplier interface inherits the CosNotifyComm::NotifySubscribe interface, an instance supporting the ProxyPullSupplier interface can be informed whenever the list of event types that the consumer connected to it is interested in receiving changes. Finally, the ProxyPullSupplier interface defines the operation which can be invoked by a pull consumer to establish the connection over which the pull consumer will receive events from the channel. Note that this can be either a pure event service style, or a notification service style pull consumer.
