ABSTRACT:
A system for sharing an interface between objects is described herein that saves significant mounts of system resources, such as memory, in an object oriented system. The interface shared by the system described herein is an interface containing methods that perform a drag and drop operation. In addition, since one instance of the interface is shared among multiple objects, the system centralizes the processing performed by the methods of the interface. This centralization includes centralizing storage and state information associated with the processing of the methods of the interface, thereby further reducing utilization of system resources. The centralized processing occurs in a system where operations are performed on objects in a distributed manner (i.e., on an object-by-object basis). In other words, in a system where operations are typically performed on an object-by-object basis, the system described herein saves system resources by providing a mechanism for centralizing the processing of operations that are to be performed on multiple objects.
