EOObserverProxy
Inherits from: Object
Package: com.webobjects.eocontrol
Class Description
The EOObserverProxy class is a part of EOControl's change tracking mechanism. It provides a means for objects that can't inherit from EODelayedObserver to handle subjectChanged messages. For an overview of the general change tracking mechanism, see "Tracking Enterprise Objects Changes" (page 22) in the introduction to the EOControl Framework.
An EOObserverProxy has a target object on whose behalf it observes objects. EOObserverProxy overrides subjectChanged to send an action message to its target object, allowing the target to act as though it had received subjectChanged directly from an EODelayedObserverQueue. See the EOObserverCenter and EODelayedObserverQueue class specifications for more information.
