The ProxyPullConsumer interface supports connections to the channel by suppliers
who will make events available for pulling to the channel as untyped Anys.
Through inheritance of the ProxyConsumer interface, the ProxyPullConsumer
interface supports administration of various QoS properties, administration of a list of
associated filter objects, and a readonly attribute containing the reference of the
SupplierAdmin object which created it. In addition, this inheritance implies that a
ProxyPullConsumer instance supports an operation which will return the list of event
types which consumers connected to the same channel are interested in receiving, and
an operation which can return information about the instance?s ability to accept a per-event
QoS request.
The ProxyPullConsumer interface also inherits from the PullConsumer interface
defined within the CosEventComm module of the OMG Event Service. This interface
supports the operation required to disconnect the ProxyPullConsumer from its
associated supplier. In addition, since the inherited PullConsumer interface inherits
the CosNotifyComm::NotifyPublish interface, a supplier connected to an instance
supporting the ProxyPullConsumer interface can inform it whenever the list of event
types the supplier plans to supply changes.
Finally, the ProxyPullConsumer interface defines the operation which can be invoked
by a pull supplier to establish the connection over which the pull supplier will send
events to the channel. Note that this can be either a pure event service style, or a
notification service style pull supplier. The ProxyPullConsumer interface also defines
a pair of operations which can suspend and resume the connection between a
ProxyPullConsumer instance and its associated PullSupplier. During the time such a
connection is suspended, the ProxyPullConsumer will not attempt to pull events from
its associated PullSupplier.
