I think you can just call

  new morphology::HfstAnalyzer(path);

The constructor is missing an implementation right now but the parameter there 
is supposed to contain the path to the directory. So no need to use 
AnalyzerFactory at all. In fact AnalyzerFactory is meant to be used only when 
you don't know (and don't care) about the concrete implementation that will be 
created. There is no need to use it when you know you want HfstAnalyzer.
