Issue 2460:  EventTypeRepository class issue (notif_service-rtf)
Source:  (, )
Nature:  Uncategorized Issue
Severity: 
Summary: Summary: In Appendix A it is stated that "the EventTypeRepository class only has
 one instance in any given implementation of the Repository". At the same
 time, there is a package interface and a package factory that implies
 that it"s possible to create multiple repositories (unless the
 NotificationTypesPackage interface is expected to always returns the
 same objects, no matter how many packages one have created).

Notification Service RTF Issue:

In Appendix A it is stated that "the EventTypeRepository class only
has
one instance in any given implementation of the Repository". At the
same
time, there is a package interface and a package factory that implies
that it's possible to create multiple repositories (unless the
NotificationTypesPackage interface is expected to always returns the
same objects, no matter how many packages one have created).

If the EventTypeRepository is meant to be a singleton within the
repository, the Contains interface is confusing as most of the
operations specifically include a repository 'container' parameter. Is
this just a result of the MOF mapping or are you for instance meant to
be able to move an event type from a repository in one package to a
repository in another package?

Is the offer_change and subscription_change operations of the
NotifyPublish and NotifySubscribe interfaces meant to raise the
InvalidEventType exception if an event type repository is present, and
the type in question has not been defined? If more than one
EventTypeRepository class is allowed, how is the notification service
meant to find them given the current IDL?

Thanks,
Bjarne.
