Interface ProxyPullSupplier
public
interface
ProxyPullSupplier
extends ProxyPullSupplierOperations, ProxySupplier, PullSupplier, Object, IDLEntity
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 instances 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.
