Interface StructuredProxyPushConsumerOperations
public
interface
StructuredProxyPushConsumerOperations
extends ProxyConsumerOperations, StructuredPushConsumerOperations
The StructuredProxyPushConsumer interface supports connections to the channel by
suppliers who will push events to the channel as Structured Events. Through
inheritance of the ProxyConsumer interface, the StructuredProxyPushConsumer
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
StructuredProxyPushConsumer 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 StructuredProxyPushConsumer interface also inherits from the
StructuredPushConsumer interface defined in the CosNotifyComm module. This
interface supports the operation which enables a supplier of Structured Events to push
them to the StructuredProxyPushConumer, and also the operation which can be
invoked to close down the connection from the supplier to the
StructuredProxyPushConsumer. In addition, since the StructuredPushConsumer
interface inherits from the NotifyPublish interface, a supplier can inform the
StructuredProxyPushConsumer to which it is connected whenever the list of event
types it plans to supply to the channel changes.
Lastly, the StructuredProxyPushConsumer interface defines a method that can be
invoked by a push-style supplier 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 connect_structured_push_supplier operation accepts as an input parameter the
reference to an object supporting the StructuredPushSupplier interface defined
within the CosNotifyComm module. This reference is that of a supplier which plans to
push events to the channel with which the target object is associated in the form of
Structured Events. This operation is thus invoked in order to establish a connection
between a push-style supplier of events in the form of Structured Events, and the
notification channel. Once established, the supplier can proceed to send events to the
channel by invoking the push_structured_event operation supported by the target
StructuredProxyPushConsumer instance. If the target object of this operation is
already connected to a push supplier object, the AlreadyConnected exception will be
raised.
Parameters: push_supplier Push supplier to connect to the proxy
Throws: CosEventChannelAdmin::AlreadyConnected The proxy is already connected
