Abstract

A method and apparatus for a data object previewer is described. In an embodiment, the invention is a method. The method includes detecting a change in a structure. The method also includes processing the structure into a preview. The method further includes presenting the preview. In another embodiment, the invention is a system. The system includes a processor, a bus coupled to the processor, and a memory coupled to the bus. The processor is to detect a change in a structure, process the structure into a preview, and present the preview.

Claims

1. A method comprising:

detecting a change in a structure;

processing the structure into a preview, including

creating an initial state model for an object of the structure in relation to a strategy of the structure,

requesting a next available option for the object in relation to the strategy,

updating the state model for the object,

determining no options are available for the object in relation to the strategy,

determining that something within the object was not reached based on the state model, and

providing an indication of an error responsive to the determining that something was not reached; and

presenting the preview.

2. The method of claim 1, wherein:

the structure is a set of learning nets, learning objects and associated strategies; and

further comprising;

repeating the detecting, processing and presenting.

3. The method of claim 2, wherein:

processing the structure into a preview further includes;

repeating the requesting and updating responsive to not determining no options are available.

4. A method comprising:

detecting a change in a structure;

processing the structure into a preview; and

presenting the preview.

5. The method of claim 4, further comprising:

repeating the detecting, processing and presenting.

6. The method of claim 4, wherein:

the structure is a set of learning nets, learning objects and associated strategies.

7. The method of claim 6, wherein:

the change is a change to a learning net.

8. The method of claim 6, wherein:

the change is a change to a learning object.

9. The method of claim 6, wherein:

the change is a change to a selection of a strategy.

10. The method of claim 6, wherein:

the change is a change to a strategy which is presently selected.

11. The method of claim 6, wherein:

the change is a change to a relationship between portions of the structure.

12. The method of claim 4, wherein:

processing the structure into a preview includes;

creating an initial state model for an object of the structure in relation to a strategy of the structure,

requesting a next available option for the object in relation to the strategy, and

updating the state model for the object.

13. The method of claim 12, wherein:

processing the structure into a preview further includes;

determining no options are available for the object in relation to the strategy.

14. The method of claim 13, wherein:

processing the structure into a preview further includes;

determining that something within the object was not reached based on the state model, and

providing an indication of an error responsive to the determining that something was not reached.

15. The method of claim 14, wherein:

processing the structure into a preview further includes;

repeating the requesting and updating responsive to not determining no options are available.

16. The method of claim 4, wherein

the structure is a set of learning nets, learning objects and associated strategies;

processing the structure into a preview includes;

creating an initial state model for an object of the structure in relation to a strategy of the structure,

requesting a next available option for the object in relation to the strategy,

updating the state model for the object,

determining no options are available for the object in relation to the strategy,

determining that something within the object was not reached based on the state model,

providing an indication of an error responsive to the determining that something was not reached, and

repeating the requesting and updating responsive to not determining no options are available;

and further comprising;

repeating the detecting, processing and presenting.

17. A system, comprising:

a processor;

a bus coupled to the processor;

a memory coupled to the bus;

wherein the processor to detect a change in a structure, process the structure into a preview, and present the preview.

18. The system of claim 17, wherein:

in processing the structure into the preview, the processor is to;

create an initial state model for an object of the structure in relation to a strategy of the structure,

request a next available option for the object in relation to the strategy, and

update the state model for the object.

19. The system of claim 18, wherein:

in processing the structure into the preview, the processor is to;

determine no options are available for the object in relation to the strategy,

determine that something within the object was not reached based on the state model, and

provide an indication of an error responsive to the determining that something was not reached.

20. The system of claim 17, wherein:

in presenting the preview, the processor is to;

present a visual representation of the structure in light of the selected strategy.

21. A medium embodying instructions, which, when executed by a processor, cause the processor to perform a method, the method comprising:

detecting a change in a structure;

processing the structure into a preview; and

presenting the preview.

22. The medium of claim 21, wherein the method further comprises:

repeating the detecting, processing and presenting.

23. The medium of claim 21, wherein:

the structure is a set of learning nets, learning objects and associated strategies.

24. The medium of claim 23, wherein:

the change is a change to a relationship between portions of the structure.

25. The medium of claim 21, wherein:

processing the structure into a preview includes;

creating an initial state model for an object of the structure in relation to a strategy of the structure,

requesting a next available option for the object in relation to the strategy, and

updating the state model for the object.

26. The medium of claim 25, wherein:

processing the structure into a preview further includes;

determining no options are available for the object in relation to the strategy.

27. The medium of claim 26, wherein:

processing the structure into a preview further includes;

determining that something within the object was not reached based on the state model, and

providing an indication of an error responsive to the determining that something was not reached.

28. The medium of claim 27, wherein:

processing the structure into a preview further includes;

repeating the requesting and updating responsive to not determining no options are available.

29. The medium of claim 21, wherein:

the structure is a set of learning nets, learning objects and associated strategies;

processing the structure into a preview includes;

creating an initial state model for an object of the structure in relation to a strategy of the structure,

requesting a next available option for the object in relation to the strategy,

updating the state model for the object,

determining no options are available for the object in relation to the strategy,

determining that something within the object was not reached based on the state model,

providing an indication of an error responsive to the determining that something was not reached, and

repeating the requesting and updating responsive to not determining no options are available;

and further comprising;

repeating the detecting, processing and presenting.

30. An apparatus, comprising:
