Abstract

A new class of data file storing objects which have the ability to self-extract, i.e. within objects in the new class, there is a method to extract selected individual files stored in the objects. There is provided a computer controlled object oriented programming system having means for interfacing a plurality of programming objects with each other and including at least one data storage object of an object class comprising means within said object for storing a plurality of data files, and means within said object for extracting said stored data files from said object. The object class is most effectively used with Java objects. The compressed files stored in the objects may be program files. The files are usually compressed into a single file for distribution. In accordance with another aspect of the present invention, there is provided for use in creating and loading the data storage objects, a file adder object interfacing with a data storage object for adding additional files to said data storage object.

Claims

1. A computer controlled object oriented programming system having means for interfacing a plurality of programming objects with each other and including at least one data storage object of an object class comprising:

means within said data storage object for storing a plurality of data files, and

means within said data storage object for extracting said stored data files from said data storage object.

2. The object oriented programming system of claim 1 wherein the Java programming language is used.

3. The object oriented programming system of claim 1 wherein at least one of said data files is stored in compressed form.

4. The object oriented programming system of claim 3 wherein said compressed file is a compressed program file.

5. The object oriented programming system of claim 4 wherein a plurality of said data files are stored in compressed form within said data storage object.

6. The object oriented programming system of claim 5 wherein said plurality of stored files are compressed together into a single file.

7. The object oriented programming system of claim 3 further including means for uncompressing extracted data files.

8. The object oriented programming system of claim 5 further including a file adder object interfacing with a data storage object for adding additional files to said data storage object.

9. A computer controlled method of object oriented programming with a plurality of programming objects interfacing with each other and including at least one data storage object of an object class enabling:

storing a plurality of data files within said data storage object, and

storing within said data storage object, a method for extracting said stored data files from within said data storage object.

10. The object oriented programming method of claim 9 wherein the Java programming language is used.

11. The object oriented programming method of claim 9 wherein at least one of said data files is stored in compressed form.

12. The object oriented programming method of claim 11 wherein said compressed file is a compressed program file.

13. The object oriented programming method of claim 11 wherein a plurality of said data files are stored in compressed form within said data storage object.

14. The object oriented programming method of claim 13 wherein said plurality of data files stored in compressed form within said data storage object are compressed together into a single file.

15. The object oriented programming method of claim 13 further including the step of uncompressing extracted data files.

16. The object oriented programming method of claim 13 further including the steps of interfacing a file adder object with a data storage object for adding additional files to said data storage object.

17. In a computer controlled object oriented programming system having means for interfacing a plurality of programming objects with each other, a computer program having program code included on a computer readable medium including at least one data storage object of an object class comprising:

means within said data storage object for storing a plurality of data files, and

means within said data storage object for extracting said stored data files from said data storage object.

18. The computer program of claim 17 wherein the Java programming language is used.

19. The computer program of claim 17 wherein at least one of said data files is stored in compressed form.

20. The computer program of claim 19 wherein said compressed file is a compressed program file.

21. The computer program of claim 19 wherein a plurality of said data files are stored in compressed form within said data storage object.

22. The computer program of claim 19 wherein said plurality of stored files are compressed together into a single file.

23. The computer program of claim 19 further including means for uncompressing extracted data files.

24. The computer program of claim 21 further including a file adder object interfacing with a data storage object for adding additional files to said data storage object.
