Philip, thank you. That's really easy and the annotator is more generell =
and even shorter in code, now.

Betreff: Re: View vs. JCas as process() argument

Armin,

This looks vaguely like something you might be tempted to try when using =
uimaFIT (as you recently mentioned you were using.)  I believe that the =
"UIMA way" is to leave your analysis engine unaware of what view it =
should work on (assuming the analysis engine works on a single view) and =
then at run time use a sofa mapping to decide which view it actually =
works on.  The easiest way to set this up in uimaFIT is to use the =
AggregateBuilder class which has an add method that looks something like
this:

builder.add(analysisEngineDescription, CAS.NAME_DEFAULT_SOFA, "ViewA");

Hope this helps.

Philip
