implements SequenceProxyPushSupplierOperations, InvokeHandler
The SequenceProxyPushSupplier interface supports connections to the channel by
consumers who will receive events from the channel as sequences of Structured
Events. Through inheritance of the ProxySupplier interface, the
SequenceProxyPushSupplier 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 SequenceProxyPushSupplier 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 SequenceProxyPushSupplier interface also inherits from the
SequencePushSupplier 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 SequenceProxyPushSupplier. In addition, since the
SequencePushSupplier interface inherits from the NotifySubscribe interface, a
SequenceProxyPushSupplier 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 SequenceProxyPushSupplier 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 SequenceProxyPushSupplier interface also
defines a pair of operations which can suspend and resume the connection between a
SequenceProxyPushSupplier instance and its associated SequencePushConsumer.
During the time such a connection is suspended, the SequenceProxyPushSupplier
will accumulate events destined for the consumer but not transmit them until the
connection is resumed.
