ProxyPushSupplier
extends ProxyPushSupplierOperations, ProxySupplier, PushSupplier, Object, IDLEntity
The ProxyPushSupplier interface supports connections to the channel by consumers
who will receive events from the channel as untyped Anys.
Through inheritance of the ProxySupplier interface, the ProxyPushSupplier interface
supports administration of various QoS properties, administration of a list of associated
filter objects, mapping filters for event priority and lifetime, and a readonly attribute
containing the reference of the ConsumerAdmin object which created it. In addition,
this inheritance implies that a ProxyPushSupplier 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 ProxyPushSupplier interface also inherits from the PushSupplier interface
defined within the CosNotifyComm module. This interface supports the operation
required to disconnect the ProxyPushSupplier from its associated consumer. In
addition, since the inherited PushSupplier interface inherits the
CosNotifyComm::NotifySubscribe interface, an instance supporting the
ProxyPushSupplier interface can be informed whenever the list of event types that the
consumer connected to it is interested in receiving changes.
Lastly, the ProxyPushSupplier 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. Note that this can be either a pure event service style,
or a notification service style push consumer.The ProxyPushSupplier interface also
defines a pair of operations which can suspend and resume the connection between a
ProxyPushSupplier instance and its associated PushConsumer. During the time such
a connection is suspended, the ProxyPushSupplier will accumulate events destined
for the consumer but not transmit them until the connection is resumed.
