You can pass models as parameters to methods (just like any other Java
object). The code in this message looks like it may have been mangled
on its way to the list. It's certainly not in a compilable state at
the moment. E.g., lines like
Product.addProperty(category_n, classDetails.get( );
don't even have balanced parentheses. It will be much easier to see
what the problem is if you can provide a minimal example that other
people can use to reproduce the error, and if you show what error
you're actually getting. E.g., when you say that "[you] tried
passing the model in a parameter list from Parser.java. It did not
work: `Annotator.printAnnotations(model).`", what do you mean that it
didn't work? Did you get a compilation error? Were you able to run
it, but it produced different results than what you'd been expected?
Or something else entirely?
