Filed:

Sep 29, 2010

Appl. No.:

12/893638

Inventors:

Benjamin J. Copass - Mequon WI, US

Assignee:

ROCKWELL AUTOMATION TECHNOLOGIES, INC. - Mayfield Heights OH

International Classification:

G06F 12/00

US Classification:

711156, 711154, 711E12001

Abstract:

Systems and methods are presented to facilitate implementation of controlling memory management, e.g., garbage collection, of computer objects based upon determination of a source side weak event and associated components. A first class determines the existence of a listener and a second class, based upon an indication from the first class, determines whether the second class should “re-register for finalization” during execution of a finalizing operation. Where existence of the second class is maintained, existence of associated components such as the first class, a delegate, a listener, and the like, is continued and data, etc., continues to be published from the weak event to the listener. Where existence of the second class is no longer maintained (e.g., the second class does not re-register for finalization), the various components, e.g., the first class, the second class, a delegate, a listener, and any other objects are available for garbage collection.

US Classification:

717136, 717165

Abstract:

Systems and/or methods are provided relating to an extensible framework. The extensible framework provides constructs with which device developers can model devices within the framework to enable a host application utilizing the framework to interact with the devices. New devices can be supported by the framework without disrupting existing devices or the host application.
