Re: [UIMA C++ Framework] making examples

  Hi,

I have a doubt regarding UIMA C++ annotator.
I'm developing a C++ annotator to be combined within a UIMA pipeline 
with other Java annotators. The point is this C++ annotator requires, as 
input capabilities, another Java annotator annotations.
My question is whether it is necessary to translate to C++ the input 
capability types defined in Java by the ohter Java annotators, as well 
as the C++ annotator types.

My idea is to develop the C++ annotator, generating the dynamic library, 
and afterwards, create an Eclipse UIMA project by using the proper 
descriptor for the C++ UIMA annotator. Then, in this UIMA project, 
include the Java types required for the C++ UIMA annotator as well as 
its own types.

Am I wrong, or would it be correct?
