Abstract

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.

Claims

1. A method in an object-oriented environment for processing data stored in a self-describing software object, said software object including data and methods that are executable by said object-oriented environment, the method comprising the computer-implemented steps of:

identifying the contents of the self-describing object;

displaying the contents of the self-describing object in a graphical user interface;

displaying graphical controls, wherein the graphical controls are used to manipulate the contents of the self-describing object;

modifying the contents of the self-describing object in response to user input to graphical controls in the graphical user interface;

constructing a new self-describing object in response to user input to graphical controls in the graphical user interface; and

wherein primitive types;

null, string, long, ulong (unsigned long), short, ushort (unsigned short), float, double, char, and octet are displayed directly in text boxes in the graphical user interface.

2. A method in an object-oriented environment for processing data stored as a CORBA software object having an object type of “

ANY”

, the object including data and methods that are executable by the object-oriented environment, the method comprising the computer-implemented steps of;

decomposing and displaying the contents of the CORBA ANY object in an easily understood form;

modifying the contents of the CORBA ANY object in an intuitive point-and-click environment;

constructing a new CORBA ANY object from other CORBA objects; and

wherein primitive types;

null, string, long, ulong (unsigned long), short, ushort (unsigned short), float, double, char, and octet are displayed directly with type-in capability to change values.

3. A data processing system including all object-oriented environment for manipulating a CORBA software object having an object type of “

ANY”

, the object including data and methods that are executable by the object-oriented environment, the data processing system comprising;

a means for decomposing and displaying the contents of a CORBA ANY type in an easily understood form;

a means for modifying the contents of a CORBA ANY TYPE in an intuitive point-and-click environment;

a means for constructing a now CORBA ANY object from other CORBA objects; and

wherein primitive types;

null, string, long, ulong (unsigned long), short, ushort (unsigned short), float, double, char, and octet are (displayed directly with type-in capability to change values.

4. A computer program product on a computer-readable medium for use in a network workstation for processing CORBA objects of type ANY, the computer program product comprising:

instructions for decomposing the contents of a CORBA ANY object;

instructions for displaying the contents of a CORBA ANY object;

instructions for modifying the contents of a CORBA ANY object;

instructions for copying data from any allowed Interface Definition Language object to a CORBA ANY object;

instructions for pasting data from a CORBA ANY object to any allowed Interface Definition Language object;

wherein the data object that is processed may be primitive or complex; and

wherein the primitive object is one of the following types;

null, string, long, ulong (unsigned long), short, ushort (unsigned short), float, double, boolean, char, octet.
