Abstract

A computer language translator that translates all or any portion thereof of source code in an original computer language to source code in a target computer language, which may then be translated back to the original language while still maintaining concept, syntax, form of expression, and formatting of the original source code.

Claims

1. A computer language translator for translating a first Object-Oriented Programming (OOP) computer language source code to a second OOP computer language source code, the translator comprising:

a computer having software executing thereon, the software having;

an emulated Application Programming Interface (API) library including a table accessible by said software;

said API library including data indicative of types of data manipulations of the first OOP computer language source code;

said API library including second computer language API equivalent functions callable by said second computer language;

said software identifying the type of data manipulation the first OOP computer language source code performs and accessing the table of said API library and correlating the type of data manipulation the first OOP computer language source code performs to second OOP computer language source code;

said software generating second OOP computer language source code based in part upon identified equivalent functions in the second computer language.

2. The computer language translator according to claim 1 wherein the translator is a bi-directional translator.

3. The computer language translator according to claim 2 wherein said translating software analyzes the second computer language source code to identify the type of data manipulation that the second computer language source code performs, accesses said library and correlates the type of data manipulation the second computer language source code performs to first computer language source code.

4. The computer language translator according to claim 3 wherein the correlation from the second computer language to the first computer language is independent of the context in which the second computer language source code is used, said translating software generates re-translated first computer language source code that emulates the type of data manipulation the second computer language source code performs.

5. The computer language translator according to claim 2 wherein the re-translated first computer language source code equates to the first computer language source code in:

context, syntax, form of expression and formatting.

6. The computer language translator according to claim 1 wherein said translating software performs a name adjustment when an incompatibility between the first computer language source code and the second computer language source code occurs.

7. The computer language translator according to claim 1 wherein the first computer language source code comprises a class.

8. The computer language translator according to claim 7 wherein the class consists of units selected from the group consisting of:

methods, data fields, inner-classes, and combination thereof.

9. The computer language translator according to claim 1 wherein the first computer language source code comprises an identifier.

10. The computer language translator according to claim 9 wherein said software performs a name adjustment when an incompatibility between the identifier and the second computer language source code occurs.

11. The computer language translator according to claim 1 wherein said software generates a tagged element inserted in the second computer language source code indicative of a type of data manipulation the first computer language source code performs.

12. The computer language translator according to claim 11 wherein the tagged element comprises information selected from the group consisting of:

formatting, translation data, and first computer language source code.

13. The computer language translator according to claim 1 wherein the first computer language is Java and the second computer language is C++, Objective-C or C#.

14. The computer language translator according to claim 1 wherein the first computer language is C# and the second computer language is C++, Objective-C or Java.

15. The computer language translator according to claim 1 wherein the first or the second computer language is a scripting language.

16. The computer language translator according to claim 15 wherein the scripting language is selected from the group consisting of JavaScript, Ruby, Python, Perl and PHP.

17. The computer language translator according to claim 1 further comprising a parser for parsing the first computer language source code into parsed elements.
