Class Observer

        Observer

Parent class for all event observers. Dispatches all received events to the Manager that created this Observer. Provides basic reference counting functionality needed by Manager to determine when an Observer can be released for garbage collection.

The reference counting provided by this class is independent of the reference counting used by CORBA. Keeping the counts separate makes it easier for the Manager to detect when an Observer can be freed in the Manager._unregisterObserver method.

Stores a reference to the creating Manager. Intializes the reference count on this object to zero.

Overrides: object.__init__

clientRef(self)

source code

clientUnref(self)

source code 

Decrements the pyLinAcc reference count on this Observer by one. This method is called when a client is unregistered in Manager to stop receiving notifications of an event type monitored by this Observer.

getClientRefCount(self)

source code 
Returns: integer
Current pyLinAcc reference count on this Observer

ref(self)

source code
