Interface TypedSupplierAdmin
- All Superinterfaces:
- FilterAdmin, FilterAdminOperations, IDLEntity, NotifyPublish, NotifyPublishOperations, Object, QoSAdmin, QoSAdminOperations, java.io.Serializable, SupplierAdmin, SupplierAdminOperations, org.omg.CosTypedEventChannelAdmin.TypedSupplierAdmin, org.omg.CosTypedEventChannelAdmin.TypedSupplierAdminOperations
public interface TypedSupplierAdmin
- extends TypedSupplierAdminOperations, SupplierAdmin, org.omg.CosTypedEventChannelAdmin.TypedSupplierAdmin, IDLEntity
The TypedSupplierAdmin interface defines the behavior supported by
objects that create and manage lists of proxy consumer objects within
a Notification Service typed event channel.
Similar to its untyped counterpart, a Notification Service typed event
channel can have any number of TypedSupplierAdmin instances associated
with it.
Each such instance is responsible for creating and managing a list of
proxy consumer objects that share a common set of QoS property settings,
and a common set of filter objects.
This feature enables clients to conveniently group proxy supplier objects
within a channel into groupings that each support a set of consumers with
a common set of QoS requirements and event subscriptions.
Note that the TypedSupplierAdmin interface inherits from SupplierAdmin
interface defined in the CosNotifyChannelAdmin module, and the
TypedSupplierAdmin interface defined in the CosTypedEventChannelAdmin
module.
These inheritance relationships have several implications for
a Notification Service style TypedSupplierAdmin instance.
First, inheritance of the SupplierAdmin interface defined in the
CosNotifyChannelAdmin module implies that in addition to being capable of
creating and managing Notification Service style typed proxy consumer
objects, a TypedSupplierAdmin instance can also create and manage
instances supporting any of the proxy consumer interfaces defined in the
CosNotifyChannelAdmin module.
In addition, since the SupplierAdmin interface defined in the
CosNotifyChannelAdmin module inherits from the SupplierAdmin interface
defined in the CosEventChannelAdmin module, a TypedSupplierAdmin can also
create and manage OMG Event service style untyped proxy consumer objects.
Likewise, inheritance of the TypedSupplierAdmin interface defined in the
CosTypedEventChannelAdmin module implies that an instance supporting the
CosTypedNotifyChannelAdmin?s version of TypedSupplierAdmin can create
and manage OMG Event Service style typed proxy consumer objects as well.
Thus, instances supporting the TypedSupplierAdmin interface defined in the
CosTypedNotifyChannelAdmin module can potentially create and manage
instances supporting any of the proxy consumer interfaces defined in the
CosEventChannelAdmin, CosNotifyChannelAdmin, CosTypedEventChannelAdmin,
and the CosTypedNotifyChannelAdmin (due to locally defined factory
operations) modules.
The implication of this is that a Notification Service style typed event
channel can support OMG Event Service style untyped and typed suppliers,
along with all variations of suppliers defined in the Notification
Service as clients.
Note also that the inherited CosNotifyChannelAdmin::SupplierAdmin
interface provides an instance supporting the
CosTypedNotifyChannelAdmin::TypedSupplierAdmin interface with the
behaviors necessary to associate unique identifiers with the proxy
consumer objects it creates.
While the TypedSupplierAdmin interface defined here is capable of
creating OMG Event Service style untyped and typed proxy supplier
objects, only instances of the proxy supplier interfaces defined in the
Notification Service can have associated unique identifiers.
Similarly, the inheritance of the SupplierAdmin interface defined in the
CosNotifyChannelAdmin module provides an instance supporting the
TypedSupplierAdmin interface defined in the CosTypedNotifyChannelAdmin
module with the behaviors necessary to maintain associated QoS property
settings and filter objects.
Note again that QoS property settings and filter objects can only be
associated with Notification Service style proxy consumers, both typed
and untyped.
Inheritance of the SupplierAdmin interface defined in
CosNotifyChannelAdmin also implies that TypedSupplierAdmin also inherits
from the NotifyPublish interface defined in CosNotifyComm.
This inheritance enables optimizing the notification of a group of proxy
consumer objects that have been created by the same TypedSupplierAdmin
instance of changes to the types of events being offered to them by
suppliers, since this inheritance enables a TypedSupplierAdmin instance
to be the target of an offer_change operation.
Lastly, inheritance of the SupplierAdmin interface defined in
CosNotifyChannelAdmin implies that an instance of the TypedSupplierAdmin
interface supports readonly attributes that maintain the unique
identifier of the instance supplied to it by its creating channel, the
object reference of the creating channel, and the flag which indicates
whether AND or OR semantics will be used when combining the filter
objects associated with a TypedSupplierAdmin with those defined on
specific proxy consumers created by the TypedSupplierAdmin.
Locally, the TypedSupplierAdmin interface supports the operations that
create new Notification Service style typed proxy consumer instances.
Note lastly that due to inheritance of the SupplierAdmin interface
defined in the CosNotifyChannelAdmin module, an instance supporting the
TypedSupplierAdmin interface supports a readonly attribute which
maintains a unique identifier assigned to the instance by the channel
which created it.
