Abstract

The present invention provides an extensible dependency management framework and method. Specifically, the present invention provides dependency management handler(s) and dispatcher(s) (e.g., revalidation and/or refactoring). The handlers are created and registered by users of the framework. When a change to a resource is detected, a notification is received by a dispatcher from an external caller. Upon receipt, the dispatcher will query an index to identify dependents, and then call a dependency management handler associated with the changed resource to obtain and implement updates for the dependents. In so doing, a list of the dependents will be provided to the dependency management handler.

Claims

1. An extensible dependency management framework, comprising:

at least one computer system including;

a dispatcher system configured to create, register, and update a set of dependency management dispatchers, wherein dependency management dispatchers of the set are configured to receive notifications when a determination is made by at least one external caller of changes to a file resource or a folder resource, and further wherein the notifications indicate changes to specific elements of the resources;

a handler system configured to create, register, and update a set of dependency management handlers that is distinct from the set of dependency management dispatchers, wherein each dependency management handler performs change management update tasks for a set of dependents of a changed resource, the change management update tasks being at least one of file resource or folder resource refactoring, or file resource or folder resource revalidation for dependent resources identified as being affected by the changed file resource or the changed folder resource; and

a change management system configured to

receive the notifications of changes to file resources or folder resources from a dependency management dispatcher of the set,

query an index to identify dependent resources affected by the changes to the specific elements of the changed file or folder resources, and

call a dependency management handler of the set associated with the changed resources to update and track the dependent resources.

2. The extensible dependency management framework of claim 1, wherein the set of dependency management handlers comprises:

a refactoring handler and a revalidation handler, and

wherein the set of dependency management dispatchers comprises at least one of;

a refactoring dispatcher or a revalidation dispatcher to receive the determination from the at least one external caller, and

wherein after receipt of a notification the dependency management dispatchers query an index to find dependents of the changed resource.

3. The extensible dependency management framework of claim 1, wherein the set of dependency management dispatchers receive the notifications from the at least one external caller that the set of dependent resources of the changed resource needs to be updated.

4. The extensible dependency management framework of claim 1, wherein the dependency management framework provides resource level management and element level management of the changes to the resources.

5. The extensible dependency management framework of claim 1, wherein the change management system further identifies the dependent resources to the set of dependency management handlers.

6. The extensible dependency management framework of claim 1, wherein the set of dependency management handlers obtains updates to the dependent resources, and manages implementation of the updates in response to the calls received from the change management system.

7. The framework of claim 1 wherein after the dependency management handlers are called and dependencies are updated because of a changed resource, additional updates in respective dependent resources are triggered and made.

8. An extensible dependency management method, comprising:

creating and registering a dependency management dispatcher and a dependency management handler distinct from the dependency management dispatcher, wherein the dependency management handler is a function specifically configured to be called and is associated with a specific file or a specific folder resource;

receiving a notification of a determination of a change to the file or folder resource at the dependency management dispatcher from an external caller, wherein the notification indicates a change to a specific element of the file or folder resource;

after receipt of the notification, the dependency management dispatcher querying an index to identify a set of dependent resources affected by the change to the specific element of the changed resource;

calling the dependency management handler associated with the changed resource to update the set of identified dependent resources for the changed resource,

implementing the updates using the dependency management handler,

wherein the implemented update using the dependency management handler comprises updating a list of dependent resources, where the list includes only dependent resources that specifically depend on a changed element of the changed folder or the changed file.

9. The extensible dependency management method of claim 8, further comprising receiving the notification at the dependency management dispatcher from the external caller that the set of dependent resources of the changed resource needs to be updated.

10. The extensible dependency management method of claim 8, wherein the dependency management handler comprises:

a refactoring handler and a revalidation handler, and

wherein the dependency management dispatcher comprises;

a refactoring dispatcher and a revalidation dispatcher, and

wherein after receipt of a notification the dependency management dispatcher queries an index to find dependents of the changed resource.

11. The extensible dependency management method of claim 8, further comprising:

obtaining an update to one of the set of dependent resources; and

implementing the update using a dependency management handler associated with the one of the set of dependent resources.

12. The method of claim 8 wherein after the dependency management handlers are called and dependencies are updated because of a changed resource, additional updates in respective dependent resources are triggered and made.

13. A program product stored on at least one non-transitory computer readable storage medium for managing dependency updates, the at least one non-transitory computer readable storage medium comprising program code for causing a computer system to:

create and register a dependency management dispatcher and a dependency management handler distinct from the dependency management dispatcher, wherein the dependency management handler is associated with at least a folder resource;

receive a notification of a determination of a change to the folder resource from the dependency management dispatcher from an external caller, wherein the notification indicates a change to a specific element of the changed resource;

having the dispatcher query an index to identify a set of dependent resources affected by the change to the specific element of the changed resource;

call the dependency management handler associated with the changed resource to update the set of dependent resources;

implement the updates using the dependency management handler, the updates being implemented by the dependency management handler by updating the set of identified dependent resources affected by the change by refactoring and revalidation of extensions of the dependent resources in the set.

14. The program product of claim 13, wherein the notification is received by the dependency management dispatcher from the external caller that the set of dependent resources of the changed resource needs to be updated and wherein the changed file is a Java file or a WDSL file, and wherein the dependency management handler is specifically associated with the specific changed resource.

15. The program product of claim 13, wherein the dependency management handler is selected from a group consisting of:

a refactoring handler and a revalidation handler, and

wherein the dependency management dispatcher is selected from a group consisting of;

a refactoring dispatcher and a revalidation dispatcher, and

wherein after receipt of a notification the dependency management dispatcher queries an index to find dependents of the changed resource.

16. The program product of claim 13, wherein the at least one non-transitory computer readable storage medium further comprises program code for causing the computer system to:

obtain updates to the set of dependent resources; and

implement the updates.

17. The program product of claim 13 wherein after the dependency management handlers update dependencies because of a changed resource, the program code further triggers the computer system to make additional updates in respective dependent resources to the changed resources.

18. A method for deploying a system for managing dependency updates, comprising:

providing a computer infrastructure configured to;

create and register a dependency management dispatcher and a dependency management handler distinct from the dependency management dispatcher, wherein the dependency management handler is associated with a file resource, a folder resource or both;

receive a notification of a determination of a change to the file resource or the folder resource from a dependency management dispatcher from an external caller, wherein the notification indicates a change to a specific element of the changed resource;

having the dispatcher query an index to identify a set of dependent resources affected by the change to the specific element of the changed resource;

call the dependency management handler associated with the changed resource to update the set of dependent resources;

implement the updates using the dependency management handler, the implementation including refactoring or revalidation of the set of dependent resources affected by the changed file resource or the changed folder resource.

19. The method of claim 18, wherein the notification is received by the dependency management dispatcher from the external caller that the set of dependent resources of the changed resource needs to be updated.

20. The method of claim 18, wherein the dependency management handler is selected from a group consisting of:

a refactoring handler and a revalidation handler, and wherein the dependency management dispatcher is selected from a group consisting of;

a refactoring dispatcher and a revalidation dispatcher.

21. The method of claim 18, wherein the computer infrastructure is further configured to:

obtain updates to the set of dependent resources; and

implement the updates, and

wherein the dependency management handler is pluggable and independently implemented.

22. The method of claim 18 further comprising:

making additional updates in respective dependent resources to a changed resource after the dependency management handlers are called because of a changed resource.
