(under subclass 300) Subject matter comprising means or steps for communication between objects (e.g., a message tells a
receiving object what to do) wherein a method or member function of a receiving object is invoked or called by a sending method of a sending object and the message passing may involve passing actual parameters (i.e., for example, either by reference or by value) to the target object.
(1) Note. Object-oriented data structure principles employed in message passing are properly classified here. Mere recitations to object oriented data structures, per se, does not automatically cause classification in this subclass. Object-oriented data structures, per se, are classified elsewhere.
(2) Note. Messaging techniques abound in the data communications arts in the form of signaling protocols, message protocols, semaphore techniques, token passing, etc. An object-oriented paradigm will present generalized functionality in a neatly reusable or customizable program code "module. Therefore, a concept search for a messaging technique should also consider the other communications classes as appropriate.
