A method and system to decompose, display, modify and substitute the contents of self-describing objects is presented. A user-friendly graphical user interface is designed to facilitate the processing of these objects. Since objects can be arbitrarily complex, the presentation of information in a clear and concise manner is critically important. The user can modify the values for existing objects, and by using the copy and paste operations, the user can construct new objects. These changes are made through the graphical user interface where the contents of the object is displayed and controls are provided to modify existing objects or to create new objects. The particular embodiment deals with CORBA objects of type ANY. Objects of ANY type include a Helper class to support the insertion and extraction of information. This class is dynamically created and invoked to assist in obtaining the contents from the ANY type. There are also methods to help narrow the type of objects. By utilizing these self-describing features, the present embodiment allows a user to decompose, display, and modify CORBA objects of type ANY, and to construct new objects of CORBA type ANY.
