Using flow controller
Hello,
I am a student studing text mining. I have a problem
about using flow controller.As you introduced,the aggregate
can use FC(flow controller) to determine the flow of the
CASes among the delegates.Now,I want to design an aggregate
including 3 AEes: AE1,AE2,AE3.
The CAS containing a Tag. The aggregate should work like
this:it first checks the value of Tag.If Tag =1,it sends
CAS to AE1.After AE1 finishes,it sends CAS to AE3.If tag=0,
it send CAS to AE2.After AE2 finishes,it sends CAS to AE3.
That is to say, the aggregate can determine the flow by
judging the value of Tag.Can the flow controller achieve
this functionality ? How to design the flow controller?
The project in apache-uima-as doesn't contain an example
about using FC like this.
I am very glad to hear your answer.

There are three sample flow controllers in the examples.
See $UIMA_HOME/examples/src/org/apache/uima/examples/flow
in the SDK image.
What you describe is pretty simple. Use WhiteboardFlowController.java,
remove most of the code and add what you need :)
