Class SequenceProxyPullSupplierPOATie

The SequenceProxyPullSupplier interface supports connections to the channel by consumers who will pull events from the channel as sequences of Structured Events. Through inheritance of the ProxySupplier interface, the SequenceProxyPullSupplier interface supports administration of various QoS properties, administration of a list of associated filter objects, and a readonly attribute containing the reference of the ConsumerAdmin object which created it. In addition, this inheritance implies that a SequenceProxyPullSupplier 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 instances ability to accept a per-event QoS request. The SequenceProxyPullSupplier interface also inherits from the SequencePullSupplier interface defined in the CosNotifyComm module. This interface supports the operations which enable a consumer of sequences of Structured Events to pull them from the SequenceProxyPullSupplier, and also the operation which can be invoked to close down the connection from the consumer to the SequenceProxyPullSupplier. In addition, since the SequencePullSupplier interface inherits from the NotifySubscribe interface, a SequenceProxyPullSupplier can be notified whenever the list of event types which its associated consumer is interested in receiving changes. This notification occurs via the callback mechanism described in section 2.3. Lastly, the SequenceProxyPullSupplier interface defines a method that can be invoked by a pull-style consumer of sequences of Structured Events in order to establish a connection between the consumer and a notification channel over which the consumer will proceed to receive events.
