extends StructuredProxyPushSupplierOperations, ProxySupplier, StructuredPushSupplier, Object, IDLEntity
The StructuredProxyPushSupplier interface supports connections to the channel by
consumers who will receive events from the channel as Structured Events. Through
inheritance of the ProxySupplier interface, the StructuredProxyPushSupplier
interface supports administration of various QoS properties, administration of a list of
associated filter objects, and a readonly attribute containing the reference of the
ConsumerAdmin object which created it. In addition, this inheritance implies that a
StructuredProxyPushSupplier 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 StructuredProxyPushSupplier interface also inherits from the
StructuredPushSupplier interface defined in the CosNotifyComm module. This
interface supports the operation which can be invoked to close down the connection
from the consumer to the StructuredProxyPushSupplier. In addition, since the
StructuredPushSupplier interface inherits from the NotifySubscribe interface, a
StructuredProxyPushSupplier can be notified whenever the list of event types which
its associated consumer is interested in receiving changes. This notification occurs via
the callback mechanism described in section 2.3.
Lastly, the StructuredProxyPushSupplier interface defines the operation which can
be invoked by a push consumer to establish the connection over which the push
consumer will receive events from the channel. The StructuredProxyPushSupplier
interface also defines a pair of operations which can suspend and resume the
connection between a StructuredProxyPushSupplier instance and its associated
StructuredPushConsumer. During the time such a connection is suspended, the
StructuredProxyPushSupplier will accumulate events destined for the consumer but
not transmit them until the connection is resumed.
