Abstract

Disclosed is a computer system capable of executing a version control program with a method within the version control program for generating an archive object for a file having an extension XXX. The method comprising the steps of receiving a request for constructing an extension object for an extension XXX from an application capable of creating extensions followed by determining if a MetaClass has been provided for the extension XXX, and if so associating the MetaClass with the extension XXX. Further, including receiving a request for creating an archive object for the extension XXX from a version control application; from a folder revision object in the version control program, determining if the extension XXX is registered with a folder archive object corresponding to the folder revision object, and if so determining if the MetaClass is associated with the extension XXX, and if so; calling an operation to create an object in the MetaClass determined in the preceding step for construction of an archive object for the extension XXX; and, returning the archive object constructed in the previous step as an archive object for the extension XXX.

Claims

1. In a computer system capable of executing a version control program, a method within said version control program for generating an archive object for a file having an extension XXX, said method comprising the steps of:

a. receiving a request for constructing an extension object for an extension XXX from an application capable of creating extensions;

b. determining if a MetaClass has been provided for said extension XXX, and if so;

c. associating said MetaClass with said extension XXX;

d. receiving a request for creating an archive object for said extension XXX from a version control application;

e. from a folder revision object in said version control program, determining if said extension XXX is registered with a folder archive object corresponding to said folder revision object, and if so;

f. determining if said MetaClass is associated with said extension XXX, and if so;

g. calling an operation to create an object in said MetaClass determined in the preceding step for construction of an archive object for said extension XXX; and

,

h. returning said archive object constructed in the previous step as an archive object for said extension XXX.

2. The method as in claim 1 where in step b no MetaClass has been provided for said extension XXX, further including the steps of creating said extension XXX without associating said extension XXX with said MetaClass and returning to said version control application.

3. The method as in claim 1 where in step e thereof it is determined that said extension XXX is not registered, further including the steps of constructing an archive object and returning said archive object to said version control application.

4. The method as in claim 1 where in step f thereof it is determined that no MetaClass is associated with said extension XXX, further including the steps of constructing an archive object and returning said archive object to said version control application.

5. The method as in claim 1 where in step c thereof, further including the steps of validating a construction operation in a class described by said MetaClass to determine if it matches a construct operation of said archive.

6. The method as in claim 1 where in step e thereof, further including the steps of calling a findExtension operation to determine if said extension XXX is registered with all ancestors of said folder archive object.

7. A storage medium encoded with machine-readable computer program code in a computer system capable of executing a version control program, a method within said version control program for incorporating changes to software releases, wherein, when the computer program code is executed by a computer, the computer performs the steps of:

a. receiving a request for constructing an extension object for an extension XXX from an application capable of creating extensions;

b. determining if a MetaClass has been provided for said extension XXX, and if so;

c. associating said MetaClass with said extension XXX;

d. receiving a request for creating an archive object for said extension XXX from a version control application;

e. from a folder revision object in said version control program, determining if said extension XXX is registered with a folder archive object corresponding to said folder revision object, and if so;

f. determining if said MetaClass is associated with said extension XXX, and if so;

g. calling an operation to create an object in said MetaClass determined in the preceding step for construction of an archive object for said extension XXX; and

,

h. returning said archive object constructed in the previous step as an archive object for said extension XXX.

8. The storage medium as in claim 7 where in step b no MetaClass has been provided for said extension XXX, further including the steps of creating said extension XXX without associating said extension XXX with said MetaClass and returning to said version control application.

9. The storage medium as in claim 7 where in step e thereof it is determined that said extension XXX is not registered, further including the steps of constructing an archive object and returning said archive object to said version control application.

10. The storage medium as in claim 7 where in step f thereof it is determined that no MetaClass is associated with said extension XXX, further including the steps of constructing an archive object and returning said archive object to said version control application.

11. The storage medium as in claim 7 where in step c thereof, further including the steps of validating a construction operation in a class described by said MetaClass to determine if it matches a construct operation of said archive.

12. The storage medium as in claim 7 where in step e thereof, further including the steps of calling a findExtension operation to determine if said extension XXX is registered with all ancestors of said folder archive object.
