Interface SequenceProxyPushSupplier

public interface SequenceProxyPushSupplier extends SequenceProxyPushSupplierOperations, ProxySupplier, SequencePushSupplier, Object, IDLEntity

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.
