The StructuredProxyPullSupplier interface supports connections to the channel by
consumers who will pull events from the channel as Structured Events. Through
inheritance of the ProxySupplier interface, the StructuredProxyPullSupplier
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
StructuredProxyPullSupplier 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 StructuredProxyPullSupplier interface also inherits from the
StructuredPullSupplier interface defined in the CosNotifyComm module. This
interface supports the operations which enable a consumer of Structured Events to pull
them from the StructuredProxyPullSupplier, and also the operation which can be
invoked to close down the connection from the consumer to the
StructuredProxyPullSupplier. In addition, since the StructuredPullSupplier
interface inherits from the NotifySubscribe interface, a StructuredProxyPullSupplier
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 StructuredProxyPullSupplier interface defines a method that can be
invoked by a pull-style consumer 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.
