摘要：An application programming interface is provided in an object-oriented

programming platform for developing applications. A method comprises registering afirst object with a second object to observe one or more properties associated with thesecond object, the second object having a set of methods associated therewith andreplacing a first implementation of a method in the set of methods associated with thesecond object with a second implementation of the method that automatically sends anotification to the first object. The observable objects need not explicitly invoke theobserver notifications, avoiding writing of a large amount of code. These observernotifications need only be sent for objects that are actually being observed but arerelated objects, substantially reducing the performance overhead of needless invocationsof the observer notifications without limiting binding between objects.
