Declared in: EOControl/EOObserver.h

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" 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.

initWithTarget:action:priority:

Initializes a new EOObserverProxy to send anAction to anObject upon receiving a subjectChanged message. anAction should be a selector for a typical action method, taking one id argument and returning void . priority indicates when the receiver is sent this message from EODelayedObserverQueue's notifyObserversUpToPriority: method. This is the designated initializer for the EOObserverProxy class. Returns self .
