SequenceProxyPullConsumer
extends SequenceProxyPullConsumerOperations, ProxyConsumer, SequencePullConsumer, Object, IDLEntity
The SequenceProxyPullConsumer interface supports connections to the channel by
suppliers who will make events available for pulling to the channel as sequences of
Structured Events. Through inheritance of the ProxyConsumer interface, the
SequenceProxyPullConsumer 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 SequenceProxyPullConsumer 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 instances ability to accept a per-event QoS request.
The SequenceProxyPullConsumer interface also inherits from the
SequencePullConsumer interface defined in the CosNotifyComm module. This
interface supports the operation which can be invoked to close down the connection
from the supplier to the SequenceProxyPullConsumer. In addition, since the
SequencePullConsumer interface inherits from the NotifyPublish interface, a
supplier can inform the SequenceProxyPullConsumer to which it is connected
whenever the list of event types it plans to supply to the channel changes.
Lastly, the SequenceProxyPullConsumer interface defines a method that can be
invoked by a pull-style supplier of sequences of Structured Events in order to establish
a connection between the supplier and a notification channel over which the supplier
will proceed to send events. The SequenceProxyPullConsumer interface also defines
a pair of operations which can suspend and resume the connection between a
SequenceProxyPullConsumer instance and its associated SequencePullSupplier.
During the time such a connection is suspended, the SequenceProxyPullConsumer
will not attempt to pull events from its associated SequencePullSupplier.
