Running a Content Pipeline
After a content pipeline has been created, an ACL function call runs it:
result = run_composer(handle, arr)
The arguments are specified as follows:
handle
is the handle returned by get_composer.
arr
is the parameter array.
If the content pipeline succeeds, the function returns 1. If an error is detected, the function returns 0.
The pipeline may leave open documents in memory or files on disk, depending on the values passed in the parameter array and the nature of the pipeline, Developers need to remember that management of these files is the responsibility of the code that created and ran the pipeline.
