Interface ProxyPullConsumer

All Superinterfaces:

public interface ProxyPullConsumer
extends ProxyPullConsumerOperations, ProxyConsumer, PullConsumer, IDLEntity

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 that created it. In addition, this inheritance implies that a ProxyPullConsumer instance supports an operation that will return the list of event types that consumers connected to the same channel are interested in receiving, and an operation that 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 that 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.
