Hi,
I am trying to run a CAS Multiplier with a Flow Controller.
My CPE is composed of :
- a Collection reader that reads an image and saves in a CAS a byte
array
of its content.
- a CAS Multiplier that currently, only creates 3 identical CASes with
same content than the initial
- Some AEs that extract the MPEG7 features of this images
- A CAS consumer that creates the XML File representing the MPEG7.
The Flow Controller I used is the WhiteBoardFlowController from the
example.
I added to this class the following:
protected Flow newCasProduced(CAS newCas,
String producedBy) {
getContext().getLogger().log(Level.SEVERE, "newCasProduced");
WhiteboardFlow flow = new WhiteboardFlow();
flow.setCas(newCas);
return flow;
}
The newCasProduced method needs to be added to the WhiteboardFlow
class, not that WhiteboardFlowController class. Otherwise it looks
like what you are doing is right.
The idea behind this is that the Flow of the new CAS might be related
to the Flow of its "parent" CAS (the one that was input to the CAS
Multiplier).
You are right though that the documentation on this could be better.

Is this subject closed?
did you find a way to run your CasMultiplier within your FlowController?
I have exactly the same goal and I can't find a way to make it working.
I would be very grateful if you could publish your solution if you had one.
Thank you very much
Regards,
Sophie
