Hi, With the C API, pipeline algorithm can be instantiated, arguments parsed, and the actual algorithm obtained and run. File output is successfully generated.
I don't see a way in the C API to obtain the pipeline algorithm step registry or access the step algorithms to obtain their argument properties and values. Would GetStepAlg() and related methods potentially be exposed in the C API at some point, along with a "GetStepRegistry"? When run as described above, the main pipeline (actual) algorithm object has an output arg of type DATASET, but it is not explicitly set and has null value even though the file output is successfully generated. I assume the dataset object is available in the output arg of the "write" step algorithm, but I haven't followed that code closely enough to understand some details. If that is correct though, could the final output dataset be propagated up to the main pipeline algorithm "output" arg? Thanks.
