Abstract

A system and method are provided for implementing an improved visual builder. A proxy tree comprised of proxy objects is visually built. Each proxy object corresponds to a target object in a runtime hierarchical target object tree. Proxy object interfaces, as seen by the user, are decoupled or separately and independently defined from the interfaces of the target objects. Accordingly, arbitrary mapping of proxy properties and operations to IDL attributes and operations is provided for. Visibility and grouping control is also provided to proxy properties and operations whereby the visual builder is not forced to present the exact attributes and operations of the target objects dictated by a given object definition which may be less user-friendly, inappropriate, or unnecessary in a visual builder environment. Provision is further made for the detachment and destruction of the proxy tree after it has realized the corresponding runtime hierarchical target object tree, thereby improving memory consumption at runtime.

Claims

1. A method for use in a computer to build during buildtime executable program code utilizable by an end user during execution at runtime, comprising the steps of:

generating a proxy object tree during said buildtime comprised of non-runtime proxy objects for creating visible runtime objects visible by said end user at said runtime,

said tree being maintained with non-visible pointers tracking relationships between said proxy objects including visual containment for visual runtime objects;

editing said proxy tree by visually manipulating representations of said proxy objects,

said representations and said proxy objects being perceptible and unperceptible by said end user during said runtime, respectively, and

said visual manipulating including storing programming information in said proxy objects for use in said creating visible runtime objects; and

generating automatically a target object tree during said runtime comprised of target objects corresponding to any programmable said runtime object from said proxy object tree.

2. The method of claim 1 wherein said generating said proxy object tree is at build time.

3. The method of claim 1 wherein said proxy objects are system object model-based.

4. The method of claim 1 further including the step of executing said executable code in functional response to said target object tree.

5. The method of claim 4 wherein prior to said executing said proxy objects are detached and erased from said computer.

6. The method of claim 1 wherein said target objects are decoupled from said proxy objects.

7. The method of claim 6 wherein properties of said proxy objects are mapped to object model-specific attributes and operations of corresponding said target objects.

8. The method of claim 7 wherein said attributes and operations are IDL attributes and IDL operations.

9. The method of claim 6 wherein operations of said proxy objects are mapped to object model-specific attributes and operations of corresponding said target objects.

10. The method of claim 9 wherein said attributes and operations are IDL attributes and IDL operations.

11. The method of claim 1 wherein each of said proxy objects corresponds to a respective one of said target objects.

12. The method of claim 1 wherein said editing said proxy object tree automatically alters said target object tree.

13. A system for use in a computer to build during buildtime executable program code utilizable by an end user during execution at runtime, comprising:

means for generating a proxy object tree during said buildtime comprised of non-runtime proxy objects for creating visible runtime objects visible by said end user at said runtime,

said tree being maintained with non-visible pointers tracking relationships between said proxy objects including visual containment for visual runtime objects;

means for editing said proxy tree by visually manipulating representations of said proxy objects,

said representations and said proxy objects being perceptible and unperceptible by said end user during said runtime, respectively, and

said means for editing including means for storing programming information in said proxy objects for use in said creating visible runtime objects; and

means for generating automatically a target object tree during said runtime comprised of target objects corresponding to any programmable said runtime object from said proxy object tree.

14. The system of claim 13 wherein said means for generating said proxy object tree generates at build time.

15. The system of claim 13 wherein said proxy objects are system object model-based.

16. The system of claim 13 further including means for executing said executable code in functional response to said target object tree.

17. The system of claim 16 wherein prior to said means for executing, said proxy objects are detached and erased from said computer.

18. The system of claim 13 wherein said target objects are decoupled from said proxy objects.

19. The system of claim 18 wherein properties of said proxy objects are mapped to object model-specific attributes and operations of corresponding said target objects.

20. The system of claim 19 wherein said attributes and operations are IDL attributes and IDL operations.

21. The system of claim 18 wherein operations of said proxy objects are mapped to object model-specific attributes and operations of corresponding said target objects.

22. The system of claim 21 wherein said attributes and operations are IDL attributes and IDL operations.

23. The system of claim 13 wherein each of said proxy objects corresponds to a respective one of said target objects.

24. The system of claim 13 wherein said means for editing said proxy object tree automatically alters said target object tree.
