Inversion of control for executable extensions in a run-time environment

1. A system for inversion of control of executable extensions, implemented as a workflow engine, the system comprising a run-time environment including:

a processor to execute the run-time environment; and

an executable extension, comprising a first component of a workflow, wherein the extension was designed, compiled, and tested with dependency on the run-time environment,

wherein the run-time environment is configured to:

read a signature within the extension, wherein the signature describes first data to be used by the extension;

push the first data from a database to the extension; and

accept a new extension, comprising a second component of the workflow,

wherein the new extension was designed, compiled, and tested independently of the run-time environment using a mock data-file or stub to provide the data described in the new signature, wherein the new extension includes a new signature,

wherein the new extension is pluggable into the workflow without specific coding to define dependencies of the new extension, and

wherein the dependencies of the new extension include at least another operation within the workflow;

read the new signature, wherein the new signature describes second data to be used by the new extension; and

push the second data from the database to the new extension.

2. The system of claim 1 , wherein the run-time environment is configured to push one or a plurality of inputs to the extension and/or the new extension.

3. The system of claim 1 , wherein the run-time environment is configured to take one or a plurality of outputs from the extension and/or the new extension.

4. The system of claim 1 , wherein said run-time environment comprises a workflow.

5. The system of claim 1 , wherein said run-time environment comprises an integrated development environment.

6. A method for inversion of control of executable extensions, implemented a workflow engine, the system comprising:

reading a signature within an extension,

wherein the extension comprises a first component of a workflow, that was designed, compiled, and tested with dependency on a run-time environment, and

wherein the signature describes first data to be used by the extension; pushing the first data from a database to the extension accepting a new extension,

wherein the new extension comprises a second component of the workflow that was designed, compiled, and tested independently of the run-time environment using a mock data-file or stub to provide the data described in the new signature,

wherein the new extension is pluggable into the workflow without specific coding to define dependencies of the new extension, and

wherein the dependencies of the new extension include at least a result of a previous operation;

read the new signature, wherein the new signature describes second data to be used by the new extension; and

pushing the second data from the database to the new extension.

7. The method of claim 6 , including pushing one or a plurality of inputs to the extension and/or the new extension.

8. The method of claim 6 , including taking one or a plurality of outputs from the extension and/or the new extension.

9. The method of claim 6 , wherein the run-time environment comprises a workflow.

10. The method of claim 6 , wherein said run-time environment comprises an integrated development environment.

11. A non-transitory computer readable medium comprising instructions, which when executed in a run-time environment cause a processor to:

read a signature within an extension,

wherein the extension comprises a first component of a workflow that was designed, compiled, and tested with dependency on the run-time environment, and

wherein the signature describes first data to be used by the extension; push the first data from a database to the extension;

accept a new extension,

wherein the new extension comprises a second component of the workflow that was designed, compiled, and tested independently of the run-time environment,

wherein the new extension is pluggable into the workflow without specific coding to define dependencies of the new extension,

wherein the new extension is configurable from outside of the new extension rather than being configurable from inside the new extension via code, and

wherein the dependencies of the new extension include at least another operation within the workflow;

read the new signature, wherein the new signature describes second data to be used by the new extension; and

push the second data from the database to the new extension.

12. The non-transitory computer readable medium of claim 11 , wherein the run-time environment is configured to push one or a plurality of inputs to the extension and/or the new extension.

13. The non-transitory computer readable medium of claim 11 , wherein the run-time environment is configured to take one or a plurality of outputs from the extension and/or the new extension.

14. The non-transitory computer readable medium of claim 11 , wherein the run-time environment comprises a workflow.

15. The non-transitory computer readable medium of claim 11 , wherein said run-time environment comprises an integrated development environment.

16. The medium of claim 11 , wherein the new extension was designed, compiled, and tested independently of the run-time environment using a mock data-file or stub to provide the data described in the new signature.

17. The system of claim 1 , wherein the dependencies of the new extension include at least the database.

18. The system of claim 1 , wherein the dependencies of the new extension further include at least a result of a previous operation.

19. The system of claim 1 , wherein the dependencies of the new extension further include at least a file object.

20. The system of claim 1 , wherein the new extension is configurable from outside of the new extension rather than being configurable from inside the new extension via code.
