Abstract

A computer program product is disclosed. The computer program product includes a computer useable medium that has a computer readable program. The computer readable program when executive on a computer causes the computer to receive a request from a component to invoke a function. Further, the computer readable program, when executed on a computer, causes the computer to asynchronously perform the function according to the request. In addition, the computer readable program, when executed on a computer, causes the computer to provide, to one or more programs, an indication that the function has completed work according to the request.

Claims

1. A computer program product comprising a computer useable medium having a computer readable program, wherein the computer readable program when executed on a computer causes the computer to:

receive a request from a component to invoke a function;

asynchronously perform the function according to the request; and

provide, to one or more programs, an indication that the function has completed work according to the request.

2. The computer program product of claim 1, wherein the computer readable program when executed on the computer further causes the computer to provide, to the one or more programs, an indication that the function has begun work according to the request.

3. The computer program product of claim 1, wherein the computer readable program when executed on the computer further causes the computer to establish a work completion contract with the one or more programs to provide the indication that the function has completed work according to the request.

4. The computer program product of claim 1, wherein the one or more programs includes an event sequencing runtime application.

5. The computer program product of claim 4, wherein the event sequencing runtime application provides a lock to the event having the request.

6. The computer program product of claim 5, wherein the event sequencing runtime application removes the lock from the event having the request after receiving the indication that the function has completed work according to the request.

7. The computer program product of claim 6, wherein the event sequencing runtime application grants the lock to another event that has an event sequencing key value that is the same as the event sequencing key value of the event.

8. The computer program product of claim 1, wherein the computer readable program when executed on a computer causes the computer to provide metadata regarding the invocation of the function to the one or more programs.

9. A method comprising:

receiving a request from a component to invoke a function;

asynchronously performing the function according to the request; and

providing, to one or more programs, an indication that the function has completed work according to the request.

10. The method of claim 9, further comprising providing, to the one or more programs, an indication that the function has begun work according to the request.

11. The method of claim 9, further comprising establishing a work completion contract with the one or more programs to provide the indication that the function has completed work according to the request.

12. The method of claim 9, wherein the one or more programs includes an event sequencing runtime application.

13. The method of claim 12, wherein the event sequencing runtime application provides a lock to the event having the request.

14. The method of claim 13, wherein the event sequencing runtime application removes the lock from the event having the request after receiving the indication that the function has completed work according to the request.

15. The method of claim 14, wherein the event sequencing runtime application grants the lock to another event that has an event sequencing key value that is the same as the event sequencing key value of the event.

16. The method of claim 9, further comprising providing metadata regarding the invocation of the function to the one or more programs.

17. A method comprising:

receiving an event that requests an invocation of a function from an event sequencing group of functions in a component, the event sequencing group being a subset of a plurality of functions in the component;

asynchronously performing the function according to the event; and

providing, to one or more programs, an indication that the function has completed work according to the event so that a lock can be removed from the event.

18. The method of claim 17, further comprising providing, to the one or more programs, an indication that the function has begun work according to the request.

19. The method of claim 17, wherein the one or more programs includes an event sequencing runtime application.

20. The method of claim 17, wherein the lock is granted to another event that has an event sequencing key value that is the same as the event sequencing key value of the event.

21. A system comprising:

a target component that receives a request from a source component to invoke a function and asynchronously performs the function according to the request; and

a work completion detection module that provides, to one or more programs, an indication that the function has completed work according to the request.

22. The system of claim 21, wherein the work completion detection module provides, to the one or more programs, an indication that the function has begun work according to the request.

23. The system of claim 21, wherein the work completion detection module establishes a work completion contract with the one or more programs to provide the indication that the function has completed work according to the request.

24. The system of claim 21, wherein the one or more programs includes an event sequencing runtime application.

25. The system of claim 24, wherein the event sequencing runtime application provides a lock to the event having the request.

26. The system of claim 25, wherein the event sequencing runtime application removes the lock from the event having the request after receiving the indication that the function has completed work according to the request.

27. The system of claim 26, wherein the event sequencing runtime application grants the lock to another event that has an event sequencing key value that is the same as the event sequencing key value of the event.

28. The system of claim 21, wherein the work completion detection module provides metadata regarding the invocation of the function to the one or more programs.
