>
> The incremental ingester and its pipeline code, and indeed transformation
> connectors themselves, do not handle the "no document" case properly.
> What should happen is that whenever a document is not retransmitted into a
> branch of the pipeline, the document version should nevertheless be recorded
> in the ingeststatus table for the corresponding output. But transformation
> connectors can interfere with that transmission if they decide simply to not
> index an incoming document. They may also receive a null RepositoryDocument
> into the transformation method, and will be unequipped to handle that.
> Instead, I propose the following:
> (1) An explicit IIncrementalIngester method needs to be invented for handling
> this case
> (2) The activity class used for transformation methods should have a
> "noDocument()" method
> (3) IncrementalIngester needs to propagate "noDocument" method calls down the
> pipeline without calling transformations on them
