Abstract

A method for enabling a first software program using a first binary specification in a first execution environment to employ a limited functionality of a second software program using a second binary specification in a second execution environment first creates a bridge in the first execution environment. Using the bridge, a proxy wrapping an interface to the limited functionality of the second software program in the second execution environment is created in the first execution environment. The proxy is used to access the limited functionality of the second software program in the second execution environment.

Claims

1. A method for enabling a first software program using a first binary specification in a first execution environment to employ a limited functionality of a second software program using a second binary specification in a second execution environment, the method comprising:

creating a bridge in said first execution environment; and

creating, in said first execution environment using said bridge, a proxy wrapping an interface to said limited functionality of said second software program in said second execution environment.

2. A method as in

claim 1

further comprising:

creating a first execution environment object including said second binary specification.

3. A method as in

claim 2

further comprising:

creating a second execution environment object including said first binary specification.

4. A method comprising:

generating a binary specification object for a first execution environment;

generating a binary specification object for a second execution environment; and

generating a bridge object wherein said bridge object is used in mapping objects from said second execution environment to said first execution environment.

5. The method of

claim 4

further comprising:

using said bridge object to generate a proxy wrapping an interface in said second execution environment.

6. A method for using functionality in a second execution environment in a first execution environment comprising:

calling a method in a proxy interface in said first execution environment; and

converting said method call by said proxy interface to a corresponding method call for execution in said second execution environment.

7. The method as in

claim 6

further comprising:

dispatching said corresponding method call for execution in said second execution environment to said second execution environment by said proxy interface.

8. The method of

claim 6

where said converting said method call further comprises:

using a type description to convert parameters from said first execution environment to said second execution environment.

9. The method of

claim 7

further comprising:

executing said corresponding method call in said second execution environment, and returning results of said execution to said proxy interface.

10. The method of

claim 9

further comprising:

using a type description to convert said returned results from said second execution environment to said first execution environment.

11. The method of

claim 6

wherein said second execution environment is a C++ programming language execution environment.

12. A method for using functionality in a second execution environment in a first execution environment comprising:

calling a method in a proxy interface in said first execution environment;

converting said method call by said proxy interface to a corresponding method call for execution in said second execution environment, wherein said converting said method call comprises;

using a type description to convert parameters from said first execution environment to said second execution environment; and

dispatching said corresponding method call for execution in said second execution environment to said second execution environment by said proxy interface.

13. The method of

claim 12

further comprising:

executing said corresponding method call in said second execution environment, and returning results of said execution to said proxy interface.

14. The method of

claim 13

further comprising:

using a type description to convert said returned results from said second execution environment to said first execution environment.

15. A computer program product comprising computer program code for a method for enabling a first software program using a first binary specification in a first execution environment to employ a limited functionality of a second software program using a second binary specification in a second execution environment, the method comprising:

creating a bridge in said first execution environment; and

creating, in said first execution environment using said bridge, a proxy wrapping an interface to said limited functionality of said second software program in said second execution environment.

16. The computer program product of

claim 15

wherein said method further comprises:

creating a first execution environment object including said second binary specification.

17. The computer program product of

claim 16

wherein said method further comprises:

creating a second execution environment object including said first binary specification.

18. A computer program product comprising computer program code for a method for using functionality in a second execution environment in a first execution environment, said method comprising:

calling a method in a proxy interface in said first execution environment; and

converting said method call by said proxy interface to a corresponding method call for execution in said second execution environment.

19. The computer program product of

claim 18

wherein said method further comprises:

dispatching said corresponding method call for execution in said second execution environment to said second execution environment by said proxy interface.

20. The computer program product of

claim 18

wherein said method further comprises:

using a type description to convert parameters from said first execution environment to said second execution environment.

21. The computer program product of

claim 19

wherein said method further comprises:

executing said corresponding method call in said second execution environment, and returning results of said execution to said proxy interface.

22. The computer program product of

claim 21

wherein said method further comprises:

using a type description to convert said returned results from said second execution environment to said first execution environment.

23. A computer storage medium having stored therein a structure comprising:

a binary specification for an execution environment including;

a simple common identity structure.

24. The computer storage medium of

claim 23

wherein said binary specification further comprises:

an extended environment structure.

25. The computer storage medium of

claim 23

wherein said simple common identity structure includes:

a type name.

26. The computer storage medium of

claim 23

wherein said simple common identity structure includes:

a method acquire.

27. The computer storage medium of

claim 23

wherein said simple common identity structure includes:

a method release.

28. The computer storage medium of
