Abstract

A method and apparatus for creating an object-oriented storage structure for storing parsed data so that it can be accessed and manipulated. A Java Archive (JAR) file containing a Manifest file is parsed and the contents placed in the object-oriented storage structure. The Manifest file contains a plurality of paragraphs where each paragraph is separated by a blank line. Each paragraph in the Manifest file is associated with an element in a Paragraph Vector in the object-oriented storage structure. Each element of the Paragraph Vector contains a reference to a Hashtable where each element in the Hashtable corresponds to a Manifest <key>:<value> pair. The storage structure is capable of dynamically growing to the necessary size of the JAR file. Paragraphs are easily added to the end of each Paragraph Vector while maintaining the ordering of the Paragraph Vectors and the performance of look-up searches.

Claims

1. A method, implemented in a computer system, for creating a storage structure for an object-oriented object, comprising the steps of:

creating said object in said computer system having a plurality of paragraphs separated by blank lines;

creating an element in a Paragraph Vector corresponding to a selected one of said plurality of paragraphs; and

associating said element in said Paragraph Vector with a reference in a hashtable corresponding to a data value pair in said selected one of said plurality of paragraphs.

2. The method of claim 1 wherein said step of creating said object further comprises:

parsing said object in said computer system for each of said plurality of paragraphs to produce a data pair for each line in said plurality of paragraphs.

3. The method of claim 1 wherein said object is a Java Bean in a Java Archive file.

4. The method of claim 1 wherein said step of creating an element further comprises:

creating a different element in said Paragraph Vector for another one of said plurality of paragraphs and appending said different element to said Paragraph Vector.

5. The method of claim 1 wherein said data value pair is a key and value for a line in said selected one of said plurality of paragraphs.

6. An apparatus for creating a storage structure for an object-oriented object, comprising:

means for creating said object in said computer system having a plurality of paragraphs separated by blank lines;

means for creating an element in a Paragraph Vector corresponding to a selected one of said plurality of paragraphs; and

means for associating said element in said Paragraph Vector with a reference in a hashtable corresponding to a data value pair in said selected one of said plurality of paragraphs.

7. The apparatus of claim 6 wherein said means for creating said object further comprises:

means for parsing said object in said computer system for each of said plurality of paragraphs to produce a data pair for each line in said plurality of paragraphs.

8. The apparatus of claim 6 wherein said object is a Java Bean in a Java Archive file.

9. The apparatus of claim 6 wherein said means for creating an element further comprises:

means for creating a different element in said Paragraph Vector for another one of said plurality of paragraphs and appending said different element to said Paragraph Vector.

10. The apparatus of claim 9 wherein said data value pair is a key and value for a line in said selected one of said plurality of paragraphs.

11. A computer program product having a computer readable medium having computer program logic recorded thereon for creating a storage structure for an object-oriented object, comprising:

computer readable means for creating said object in said computer system having a plurality of paragraphs separated by blank lines;

computer readable means for creating an element in a Paragraph Vector corresponding to a selected one of said plurality of paragraphs; and

computer readable means for associating said element in said Paragraph Vector with a reference in a hashtable corresponding to a data value pair in said selected one of said plurality of paragraphs.

12. A computer program product of claim 11 wherein said computer readable means for creating said object further comprises:

computer readable means for parsing said object in said computer system for each of said plurality of paragraphs to produce a data pair for each line in said plurality of paragraphs.

13. A computer program product of claim 11 wherein said object is a Java Bean in a Java Archive file.

14. A computer program product of claim 11 wherein said computer readable means for creating an element further comprises:

computer readable means for creating a different element in said Paragraph Vector for another one of said plurality of paragraphs and appending said different element to said Paragraph Vector.

15. A computer program product of claim 11 wherein said data value pair is a key and value for a line in said selected one of said plurality of paragraphs.
