Abstract

Embodiments of the present invention include systems and methods for template reverse engineering. In one embodiment, the present invention includes a computer-implemented method for code generation comprising receiving a template for generating code, receiving a model for generating code, processing the template and the model in a code generator, and in accordance therewith, generating code based on the model and the template, and automatically identifying a common program code construct in two or more of the generated code files. The common code may be automatically extracted from the generated code and embedded in a framework, and the templates may be modified to reference the framework.

Claims

1. A computer-implemented method of generating computer program code comprising:

receiving one or more templates for generating code;

receiving at least one model for generating code;

processing the one or more templates and the model in a code generator executable on a computer system to generate a plurality of code files containing program code based on the model and the one or more templates;

automatically identifying a common program code construct in two or more of the generated code files; and

automatically modifying each template used to generate the common program code construct to include a reference to a code framework, said code framework including said common program code construct.

2. The computer-implemented method of claim 1 further comprising, after said step of identifying, automatically moving the identified common program code construct to the code framework.

3. The computer-implemented method of claim 1 wherein said common code construct is included in a plurality of different program classes in the generated code files, the method further comprising:

creating a parent class;

storing the common program code construct in the parent class; and

creating an inheritance between the parent class and said plurality of different program classes in the generated code files.

4. The computer-implemented method of claim 3 wherein said reference to the code framework is a reference to said parent class.

5. The computer-implemented method of claim 1 wherein the code framework is accessible by the generated code files.

6. The computer-implemented method of claim 1 wherein the common program code construct in said two or more generated code files are each generated based on the same portion of one or more templates.

7. The computer-implemented method of claim 1 further comprising generating modified code based on said model and said modified templates, said modified code including said references to said code framework.

8. The computer-implemented method of claim 7 wherein, upon execution of said generated modified code, said generated modified code uses said references to said code framework to access said common program code constructs.

9. A computer-implemented system comprising:

a code generator, executable on a computer, for receiving at least one software model and one or more templates for generating code, wherein the software model specifies the software operations and comprises a plurality of elements to be translated into code constructs, and wherein the template specifies code constructs to be used from the plurality of elements in said software model, the code generator processing the one or more templates and the software model, and in accordance therewith, generating a plurality of code files containing program code based on the software model and the one or more templates;

a framework generator, executable on said computer, for automatically identifying a common program code construct in two or more of the generated code files and moving said common program code construct in a code framework; and

a code-to-template change processor, executable on said computer, for automatically modifying each template used to generate the common program code construct to include a reference to a code framework.

10. The computer-implemented system of claim 9 wherein said common code construct is included in a plurality of different program classes in the generated code files, and wherein the framework generator creates a parent class and creates an inheritance between the parent class and said plurality of different program classes in the generated code files.

11. The computer-implemented system of claim 10 wherein said reference to the code framework is a reference to said parent class.

12. The computer-implemented system of claim 9 wherein the code framework is accessible by the generated code files.

13. The computer-implemented system of claim 9 wherein the code framework is static.

14. A non-transitory computer-readable medium containing instructions for controlling a computer system to perform a method, the method comprising:

receiving one or more templates for generating code;

receiving at least one model for generating code;

processing the one or more templates and the model in a code generator executable on a computer system to generate a plurality of code files containing program code based on the model and the one or more templates;

automatically identifying a common program code construct in two or more of the generated code files; and

automatically modifying each template used to generate the common program code construct to include a reference to a code framework, said code framework including said common program code construct.

15. The non-transitory computer-readable medium of claim 14, the method further comprising, after said step of identifying, automatically moving the identified common program code construct to the code framework.

16. The non-transitory computer-readable medium of claim 14 wherein said common code construct is included in a plurality of different program classes in the generated code files, the method further comprising:

creating a parent class;

storing the common program code construct in the parent class; and

creating an inheritance between the parent class and said plurality of program classes in the generated code files.

17. The non-transitory computer-readable medium of claim 16 wherein said reference to the code framework is a reference to said parent class.

18. The non-transitory computer-readable medium of claim 14 wherein the code framework is accessible by the generated code files.

19. The non-transitory computer-readable medium of claim 14 wherein the code framework is static.

20. The non-transitory computer-readable medium of claim 14, the method further comprising generating modified code based on said model and said modified templates, said modified code including said references to said code framework, wherein, upon execution of said generated modified code, said generated modified code uses said references to said code framework to access said common program code construct.
