The watcher.objects.base Module

Watcher common internal object model

class watcher.objects.base.WatcherObject(context=None, **kwargs)

Bases: oslo_versionedobjects.base.VersionedObject

Base class and object factory.

This forms the base of all objects that can be remoted or instantiated via RPC. Simply defining a class that inherits from this base class will make it remotely instantiatable. Objects should implement the necessary “get” classmethod routines as well as “save” object methods as appropriate.

classmethod register_notification(notification_cls)

Register a class as notification.
