Abstract

A method for handling events in compositional applications represented as processing graphs, including: receiving an event notification; modifying a planning domain according to the event notification; generating a new processing graph for a previously deployed processing graph by using the modified planning domain; determining if the new processing graph is different than the previously deployed processing graph; and if the processing graphs are different: reconfiguring the previously deployed processing graph to match the new processing graph; or deploying the new processing graph and replacing the previously deployed processing graph with the newly deployed processing graph.

Claims

1. A method for handling events in compositional applications represented as processing graphs, comprising:

receiving an event notification;

modifying a planning domain according to the event notification;

generating a new processing graph for a previously deployed processing graph by using the modified planning domain;

determining if the new processing graph is different than the previously deployed processing graph; and

if the processing graphs are different;

reconfiguring the previously deployed processing graph to match the new processing graph;

or

deploying the new processing graph and replacing the previously deployed processing graph with the newly deployed processing graph.

2. The method of claim 1, wherein the event notification is initiated by an execution environment.

3. The method of claim 1, wherein the event notification is triggered by a component in the previously deployed processing graph.

4. The method of claim 1, wherein the planning domain includes a plurality of component descriptions.

5. The method of claim 4, wherein the event notification includes a request to change the planning domain.

6. The method of claim 5, wherein the request is a request to remove a component description from the planning domain, a request to add a component description to the planning domain or a request to change a component description already in the planning domain.

7. The method of claim 6, wherein a request to change a component description already in the planning domain involves changing an input condition or an output description of the component.

8. The method of claim 1, further comprising:

presenting a user with the new processing graph; and

providing the user with a choice as to whether they wish to replace the previously deployed processing graph with the new processing graph.

9. A system for handling events in compositional applications represented as processing graphs, comprising:

a memory device for storing a program;

a processor in communication with the memory device, the processor operative with the program to;

receive an event notification;

modify a planning domain according to the event notification;

generate a new processing graph for a previously deployed processing graph by using the modified planning domain;

determine if the new processing graph is different than the previously deployed processing graph; and

if the processing graphs are different;

reconfigure the previously deployed processing graph to match the new processing graph;

or

deploy the new processing graph and replace the previously deployed processing graph with the newly deployed processing graph.

10. The system of claim 9, wherein the event notification is initiated by an execution environment.

11. The system of claim 9, wherein the event notification is triggered by a component in the previously deployed processing graph.

12. The system of claim 9, wherein the planning domain includes a plurality of component descriptions.

13. The system of claim 12, wherein the event notification includes a request to change the planning domain.

14. The system of claim 13, wherein the request is a request to remove a component description from the planning domain, a request to add a component description to the planning domain or a request to change a component description already in the planning domain.

15. The system of claim 14, wherein a request to change a component description already in the planning domain involves changing an input condition or an output description of the component.

16. The system of claim 9, wherein the processor is further operative with the program to:

present a user with the new processing graph; and

provide the user with a choice as to whether they wish to replace the previously deployed processing graph with the new processing graph.

17. A computer readable storage medium storing instructions that, when executed by a computer, cause the computer to perform a method for handling events in compositional applications represented as processing graphs, the method comprising:

receiving an event notification;

modifying a planning domain according to the event notification;

generating a new processing graph for a previously deployed processing graph by using the modified planning domain;

determining if the new processing graph is different than the previously deployed processing graph; and

if the processing graphs are different;

reconfiguring the previously deployed processing graph to match the new processing graph;

or

deploying the new processing graph and replacing the previously deployed processing graph with the newly deployed processing graph.

18. The computer readable medium of claim 17, wherein the event notification is initiated by an execution environment.

19. The computer readable medium of claim 17, wherein the event notification is triggered by a component in the previously deployed processing graph.

20. The computer readable medium of claim 17, wherein the planning domain includes a plurality of component descriptions.

21. The computer readable medium of claim 20, wherein the event notification includes a request to change the planning domain.

22. The computer readable medium of claim 21, wherein the request is a request to remove a component description from the planning domain, a request to add a component description to the planning domain or a request to change a component description already in the planning domain.

23. The computer readable medium of claim 22, wherein a request to change a component description already in the planning domain involves changing an input condition or an output description of the component.

24. The computer readable medium of claim 17, the method further comprising:

presenting a user with the new processing graph; and

providing the user with a choice as to whether they wish to replace the previously deployed processing graph with the new processing graph.
