Inherited from AnnounceableResource:

Method __init__ Initialization of a Resource instance.
Method activate This method is called to activate a resource, usually in a CREATE request.
Method addAnnouncementToResource Add anouncement information to the resource. These are a list of tuples of the csi to which the resource is registered and the CSE-relative ri of the resource on the remote CSE. Also, add the reference in the at attribute.
Method createAnnouncedResourceDict Create the dict stub for the announced resource.
Method getAnnouncedTo Return the internal announcedTo list attribute of a resource.
Method removeAnnouncementFromResource Remove anouncement information from the resource. These are a list of tuples of the csi to which the resource is registered and the CSE-relative ri of the resource on the remote CSE. Also, remove the reference from the at attribute.
Method setAnnouncedTo Set the internal announcedTo list attribute of a resource.
Method update Update, add or remove resource attributes.
Method validate Validate a resource.
Method validateAnnouncedDict Possibility to add or modify the announced Dict. This can be implemented in the child classes.
Class Variable announcementManager Injected AnnouncementManager instance.
Class Variable validator Injected Validator instance.
Method _createAnnouncedDict Actually create the resource dict.
Method _getAnnouncedAttributes Return a list of mandatory and optional announced attributes. The function only returns those attributes that are also present in the resource!
Instance Variable _origAA Store the original announceableAttributes for later use in the update so that we can check whether they are removed.
Instance Variable _origAT Store the original at attribute for later use in the update so that we can check whether it is removed.
