ApplicationNo. 602442 filed on 10/23/1990US Classes:719/316Managed object systemExaminersPrimary: Harrell, Robert B.Attorney, Agent or FirmInternational ClassG06F 013/00AbstractA system for implementing a messenger and object manager in an object oriented programming environment on a data processor containing a memory, in which objects are categorized into one or more classes which define methods of the objects categorized therein, and in which messages are sent by the data processor to objects to perform actions thereon. The system includes a message call processing procedure operating on the data processor for processing message calls to instances, including a method resolution segment for calling a loaded classes table to determine whether the class corresponding to a method of the instance is loaded, where the method corresponds to the action requested by the message. If the corresponding class is not loaded in main memory, then the system dynamically loads the class. A data resolution segment calls an object management table to resolve an indirection pointer which points to the address of a data frame corresponding to the instance.Other References
